The LOGIQ V Identity Problem: Leftover Notes vs. Catalog Truth

Hospital clinical engineering, healthcare technology management (HTM) fleets, independent service organizations (ISOs), and parts distributors searching ge logiq v2 board repair or ge logiq v5 board repair currently land on a fragmented SERP: iFixit V2/V1 and V5/V3 DIY wikis, Rongtao’s own GE brand hub, whole-unit vendor pages, JustAnswer threads, laptop LOGIQ e repair copy, leftover LOGIQ P5 SYSCON titles, LOGIQ 9 YouTube, and a concatenated Rongtao model dump ¹⁰. The missing decision is not another teardown. It is which etched suffix you actually have.

Coverage on /brands/ge lists Logiq V1/V2/V3/V5 as a distinct token from Logiq E9/E10/E11, Logiq P5/P6/P7/P9, and Vivid T8/T9 ⁹. Catalog photography does not treat that coverage string as one parts list. The unique photographed V host is Motherboard 5490324-5 on model LOGIQ V5. The V1/V2 adapter and the V3/V5/T8/F8 trackball are different SKUs. Leftover notes for unlabeled V2 IO and V3 AC/DC are shopping dumps, not catalog identity.

Laptop LOGIQ e is a different machine. Catalog TX64 5436388 is a LOGIQ E row, and the dedicated LOGIQ e family path already owns that laptop architecture. LOGIQ P5 SYSCON leftovers such as 5177848-3 belong on the LOGIQ P family path. Search overviews that treat those pages as V2/V5 proof are the baseline this article is written to beat.

1. When Does FDA Language Name LOGIQ V1, V2, V3, and V5, and Why Is Combined V Naming Not a License to Swap Leftover LOGIQ P5 SYSCON or K260673 LOGIQ Vita?

Diagnostic ultrasound platforms fall primarily under product code IYN (21 CFR 892.1550, Class II), with IYO (21 CFR 892.1560) and ITX (21 CFR 892.1570) as adjacent ultrasound codes ¹. Internal boards are console assemblies. That classification does not make leftover shopping titles interchangeable.

A bounded unique-k count from the 22 July 2026 CDRH 510(k) extract (175,559 rows; 2,475 unique 510(k) numbers under IYN/IYO/ITX), corroborated by openFDA last_updated 2026-09-07, finds three unique clearances whose device_name explicitly names LOGIQ V1, V2, V3, or V5 ²³⁴:

• K141768: Traditional 510(k), decision date 4 August 2014, SESE, primary IYN, device_name LOGIQ V5/LOGIQ V3.
• K153037: Traditional 510(k), decision date 4 January 2016, SESE, primary IYN, device_name LOGIQ V1/ LOGIQ V2.
• K161224: Traditional 510(k), decision date 5 August 2016, SESE, primary IYN, device_name LOGIQ V5 Expert, LOGIQ V5, LOGIQ V3. Combined later Expert naming is still this compact V family in FDA language; it is not leftover LOGIQ P5 SYSCON 5177848-3.

Those pmn.cfm records were not used as unread 510(k) PDFs. This page does not invent predicate devices, probe lists, or internal architecture from summaries that were not fetched. The usable fact is the named device_name lineage: three V clearances, not a swap license into laptop LOGIQ e or console LOGIQ P5.

Leave-this-page collision records, independently checked on the same openFDA snapshot:

• Compact LOGIQ e / i examples that currently pollute the V2 family SERP: K072797 (Special, 17 October 2007, IYO, GE LOGIQ I COMAPACT ULTRASOUND / GE LOGIQ E COMPACT ULTRASOUND / GE VIVID E COMPACT ULTRASOUND) and K113690 (Special, 29 December 2011, IYN, GE LOGIQ I, LOGIQ E AND VIVID E). Those two are SERP collision examples, not a complete LOGIQ e unique-k census. The same 22 July 2026 extract yields eight compact e/i unique k numbers under IYN/IYO/ITX (including later LOGIQ e records such as K091374, K102256, K133533, K151028, K232186, and K260398). None of those eight is catalog 5490324-5.
• Console LOGIQ P5: K060993 (Special, 3 May 2006, IYN, GE LOGIQ P5 AND A5) and K101878 (Special, 31 August 2010, IYN, GE LOGIQ P5 MODEL H44662LD). Named P5 unique k under the same ultrasound-code filter is 2.
• LOGIQ Vita / LOGIQ S20: K260673 (Traditional, 24 March 2026, IYN). A logiq-v regex will catch Vita. Coverage does not list LOGIQ Vita or LOGIQ S20. Combined Vita/S20 naming is not catalog 5490324-5.

510(k) clearance is marketing authorization lineage, not an OEM end-of-support notice and not a pin map. Do not treat K153037 as an EOS playbook for V2, and do not treat K161224 as permission to order leftover P5 SYSCON into a V5 cage.

2. Which V-Series Board Domain Does My Symptom Point to After a Known-Good Probe, and When Is Catalog 5490324-5 a Host Ticket Rather Than an Adapter or DC Order?

Do not condemn Motherboard 5490324-5 from a shopping title. After a known-good probe, route the symptom to the parent that already owns that physics. This page does not reprint portable lithium/adapter/DC trees, CMOS coin-cell recipes, or invented rail voltages ¹¹¹².

1. Rule 1 — Probe isolation. Disconnect other probes. Connect a known-good transducer on an alternate port. If the fault follows the probe, stop this page and use probe evaluation via probe repair. If all known-good probes fail handshake across ports, treat it as a console front-end ticket after matching, not a host order.
2. Rule 2 — Power before host. If the cart is dark (no fans, no LEDs), match adapter 5653873-2 on V1/V2 or inventory V3 DC 5489508 on a labeled V3 before ordering 5490324-5. Unmatched rails-down tickets go to the cart PSU parent.
3. Rule 3 — Power-present boot. If fans and LEDs are present but the scanning UI never appears, match 5490324-5 and follow the host/HDD parent. Do not reprint that matrix here.
4. Rule 4 — Peripheral versus host. If imaging works but network/video/export or the trackball fails, match inventory IO 5546692 or catalog trackball 42PBNC200 before assuming the host bus failed. Leftover unlabeled 5548692 is not automatic identity.

3. Why Is Catalog LOGIQ V5 Motherboard 5490324-5 Not Leftover Unlabeled 5548692, Inventory 5546692, Catalog Adapter 5653873-2, or Laptop LOGIQ e TX64 5436388?

The information gain on this page is the leftover-suffix split. Catalog photos, inventory labels, and migrated leftover notes are three different evidence layers. Combined shopping titles are one leftover identity chain, not independent confirmation that two PNs are interchangeable ⁸.

4. If the Cart Is Dark, Why Must I Clear Catalog 5653873-2 and Inventory 5489508 on the Portable Parent Before Condemning 5490324-5?

A dark cart and a logo freeze are different tickets. A dark cart has no fans and no LEDs. A logo freeze has power present and a splash or OS hang. Mixing those two is how leftover adapter titles become wrongful host orders ¹¹¹².

On portable LOGIQ V1/V2, catalog 5653873-2 is the photographed adapter. The portable-power parent already owns that SKU. Confirm a known-good labeled adapter and a known-good outlet before opening the console. This page does not publish barrel voltages, MOSFET failure modes, or load-collapse recipes that are not on the adapter label in catalog ground truth.

Inventory 5489508 is labeled LOGIQ V3 DC, with a leftover note at /blog/ge-logiq-v3-dc-5489508. The portable-power parent already names that row. Clear it on a labeled V3 after a known-good adapter path. Do not map 5489508 onto every V5 cage because the coverage string lists V3 and V5 together. Leftover 5489989 is a V3 AC dump with no catalog or inventory row this snapshot.

If power is present and the unit hangs on the GE splash or never reaches the scanning UI, stop treating it as an adapter ticket. Match catalog 5490324-5 and follow the host vs HDD parent. That parent already lists this SKU among remaining host rows. There is no Rongtao LOGIQ V photo case in the current case library; do not invent a success rate, a Southbridge diagnosis, or a SMART-pass statistic from iFixit or vendor copy.

5. When Must I Refuse Z-2029-2025 as a LOGIQ V Chassis-Board Condemnation?

openFDA enforcement last_updated 2026-09-09 records Z-2029-2025 as a Class II Ongoing action, event 96992, initiated 16 May 2025, product GE Healthcare LOGIQ F R3 catalog 5943263 ⁶. The official reason is that Estimated Fetal Weight (EFW) measurement data on Versana Premier R3 and LOGIQ F R3 series systems can display previous obstetric patient data in the Whizz report. Sibling Z-2030-2025 is the Versana Premier R3 family on the same event and reason.

Neither action names LOGIQ V1, V2, V3, or V5 chassis boards. Keep those software gates on the LOGIQ F8 / Vivid T8 family path, which already records them. Shared event 96992 does not convert an F/Premier software calculation issue into a V host-board recall. Do not dump customer serials from the enforcement record.

Quoted hardware-PN searches for 5490324, 5546692, 5548692, 5489508, 5489989, and 42PBNC200 returned 0 hits in the 22–24 July 2026 CDRH recall extract (58,785 rows) and openFDA recall NOT_FOUND last_updated 2026-09-17. Hyphenated openFDA searches for 5490324-5 and 5653873-2 returned unrelated first-page rows (Baxter Colleague pumps / Ultima OPCAB). Those hyphenated totals are not published as LOGIQ V recalls.

Quoted MAUDE model_number searches for 5490324-5, 5546692, 5548692, 5489508, and 5653873-2 returned NOT_FOUND as of last_updated 2026-09-08 ⁷. Passive-surveillance emptiness is not proof the boards never fail, not an incidence rate, and not a reason to skip qualified bench diagnosis.

6. If /models/ge-logiq-v3-v5-t8-f8 Already Exists, Why Is That a Taxonomy Dump from Shared Trackball 42PBNC200 Rather Than a Parts List?

The live model page /models/ge-logiq-v3-v5-t8-f8 exists because catalog model LOGIQ V3 V5 T8 F8 is the concatenated string on Trackball JS36C-42PBNC200. Search can index that dump as if V3, V5, Vivid T8, and LOGIQ F8 shared a cage. They share a photographed trackball SKU, not a host or DC license.

Use /models/ge-logiq-v5 for the unique V5 host photograph and /models/ge-logiq-v1-v2 for the V1/V2 adapter photograph. Coverage lists Logiq V1/V2/V3/V5 and, separately, Logiq F6/F8 and Vivid T8/T9 ⁹. Trackball tickets stay on the F8/T8 family and the control-panel parent. Do not install an unmatched T8 or F8 power or processing assembly into a V5 chassis from that concatenated URL.

7. Where iFixit V2/V1 DIY, Scribd V5/V3 SM, and Leftover P5 SYSCONPM Queries Go

The 19 September 2026 V2 family SERP is a DIY and wrong-generation dump. The V5 companion mixes OEM Service Shop, gated manuals, DOTmed LOGIQ P5, and leftover P5 SYSCONPM. Both AI Overviews already extract the wrong identity ¹⁰.

• iFixit GE Logiq V2 V1 and V5/V3 DIY, including Direction 5610739-100 language and J13 pinout copy in search overviews: leave-this-page. Not a qualified-service boundary and not catalog 5490324-5.
• Scribd or other gated V5/V3 service-manual fragments: not an IFU on this site. Do not treat a paywalled PDF as a swap license.
• Leftover LOGIQ P5 SYSCONPM 5177848-3 and DOTmed LOGIQ P5 whole-unit listings: cite the LOGIQ P family. Related architecture language in an AI Overview is not K161224-as-P5-hardware.
• The Ultrasound Source LOGIQ e repair and Acme LOGIQ e NextGen pages ranked against V2: cite the LOGIQ e family. Standby-switch copy for a laptop e is not V2 proof.
• LOGIQ 9 FEPS YouTube and Voluson Facebook motherboard threads: wrong generation / wrong family. Coverage does not list LOGIQ 9 on the V token.
• Rongtao /brands/ge at organic 2: brand hub, not this leftover-suffix matrix. This article is the missing V destination of that hub.

8. Where Rongtao Fits — and Where It Does Not

Rongtao Medical is a multi-brand ultrasound board-repair and tested-parts supplier. GE names on this page identify coverage and catalog compatibility only. They do not imply OEM authorization, affiliation, or endorsement ⁹.

Where Rongtao fits

• Component-level board diagnosis and repair, and tested replacement modules, after the etched suffix is matched — including catalog V5 host 5490324-5 and inventory V2 IO 5546692 when those labels actually match the board in hand.
• Published depot terms: typical 5–8 business-day board-repair turnaround, 48-hour real-machine testing inside an actual ultrasound system, and a typically 90-day warranty, confirmed per item. Do not scrape iFixit, Acme, or JustAnswer warranty copy.
• Identity isolation this page actually owns: leftover unlabeled 5548692 versus inventory 5546692 versus catalog 5490324-5, plus routing to the portable, host, LOGIQ e, LOGIQ P, and F8/T8 parents.

Where Rongtao does not fit

• No LOGIQ V photo case exists in the current case library. This page does not publish a V-series success rate, a bench teardown from iFixit, or a whole-unit vendor as Rongtao evidence.
• No remote certainty. A quote still needs label photos, the etched PN, the symptom, quantity, and destination.
• No on-site hospital dispatch and no cracked software-option keys. Option-key work after a board swap is a different, data-gated topic.
• No DIY FRU procedure, no AI-overview pinouts, and no instruction to open energized equipment.

9. Quote-Ready Intake Checklist for GE LOGIQ V2/V5 Board Repair

Send the packet through the contact form. A labeled RFQ is the conversion path this article earns; catalog photos are not a stock promise ⁹.

1. OEM and exact model as printed on the cart (LOGIQ V1, V2, V3, V5, or V5 Expert — not a leftover shopping title).
2. Etched board part number and revision from the PCB silkscreen or barcode, for example 5490324-5, 5546692, or 5548692, not only the chassis model.
3. Clear photos of both sides of the board, including labels, serial stickers, and any visible damage.
4. Symptom in one sentence: dark cart, splash/OS hang, probe handshake after a known-good probe, dropout, trackball, or IO/video/DICOM.
5. Whether a known-good probe was tried on an alternate port, and whether a known-good labeled adapter was tried on V1/V2.
6. Quantity and destination so the quote can include logistics.

10. Frequently Asked Questions (FAQ)

Is leftover unlabeled 5548692 the same board as inventory LOGIQ V2 IO 5546692 or catalog V5 Motherboard 5490324-5?
No. Catalog 5490324-5 is the photographed LOGIQ V5 host. Inventory 5546692 is labeled LOGIQ V2 IO. Leftover 5548692 does not attach a model name; inventory also holds one 5548692 row labeled model V2. Combined leftover/inventory titles are not a pin-for-pin license. Match the etched suffix ⁸.

Does a leftover title that concatenates V3/V5/T8/F8 mean I can swap trackball 42PBNC200 or V3 DC 5489508 into any V2 cage?
No. /models/ge-logiq-v3-v5-t8-f8 is the taxonomy dump from catalog trackball 42PBNC200. Inventory 5489508 is LOGIQ V3 DC on the portable parent. Shared UI or a V3 DC label is not a host swap into every V2 cage.

Is LOGIQ V2 the same machine as laptop LOGIQ e, LOGIQ P5, LOGIQ 9, or LOGIQ Vita, and does K153037 make this an end-of-support playbook?
No. K153037 names LOGIQ V1/ LOGIQ V2 ³. Laptop LOGIQ e records such as K072797 / K113690, LOGIQ P5 records K060993 / K101878, and K260673 LOGIQ Vita / S20 are leave-this-page ⁵. A 510(k) decision date is clearance lineage, not an OEM end-of-support mandate. Coverage does not list LOGIQ 9 or LOGIQ Vita on the V token.

My search mixed V2 with iFixit DIY, Scribd V5/V3 SM, or leftover P5 SYSCONPM. Which page owns those?
iFixit and gated manuals are SERP baseline, not this site’s IFU ¹⁰. Laptop LOGIQ e standby-switch copy belongs on the LOGIQ e family path. SYSCONPM 5177848-3 belongs on the LOGIQ P family path. This page owns V leftover-suffix isolation around 5490324-5.

The cart will not power. Is that catalog adapter 5653873-2, inventory V3 DC 5489508, or host 5490324-5?
On portable V1/V2, clear catalog adapter 5653873-2 first via the portable-power parent ¹¹. On a labeled V3, inventory 5489508 is the DC row to match. Host 5490324-5 is a V5 motherboard ticket after power is present or after those power labels have been cleared — not a first dark-cart guess for every V cart.

Can I follow iFixit GE Logiq V2/V1 DIY or the V5 AI Overview J13 pinout copy to open this cart myself?
No. This page does not republish FRU disassembly or pinout steps. Ultrasound servicing belongs with qualified personnel using ESD-safe methods and the applicable OEM instructions. Unqualified readers should not open energized equipment or return a system to clinical use without qualified testing ¹⁰.
