Forum rules: Click here to view the forum rules
- Topic title should contain: the device's manufacturer, full model and the brief description of problem.
- Topic message should contain: the PCB marking code (required in case of hardware repairs), an extended description of problem, things you have checked/replaced/measured, your conclusions and the question. If you are not able to find the PCB marking code, please read THIS TOPIC. If you still cannot locate the PCB markings, please upload a clean, both-side photos of the mainboard - it is required to remove any films, modules or brackets possibly covering these markings.
- Before posting a new topic please read all topics in TRAININGS subforum and make a preliminary diagnostic based on the content of those trainings.
- Uploading of any complete schematics, BIOS files or any other kind of documentation, or linking to 3rd party websites with such files, is STRICTLY PROHIBITED. You can only upload the small portion of documentation or, link to BIOS file on UNVERIFIED BIOS FILES subforum, which simplifies the diagnostics/repair. You are not allowed to upload more then one complete page of instruction/schematic per single topic. The file you upload must not contain any watermarks, "confidential" markings, links or email addresses and cannot be password-protected.
- It is only permitted to describe one faulty device per single topic - you should always open a new topic for each subsequent device.
- Requesting of the full schematics, BoardView files, BIOS files or any other kind of documentation is NOT ALLOWED in this subforum. If you need to ask for any of these, you should open a new topic in DOCUMENTATION/BIOS REQUEST subforum.

Płyta bez reakcji na włącznik, po podłączeniu do zasilacza serwisowego gdzieś zwiera, napięcie spada do 2,7V, a prąd rośnie do ponad 5A i blokowany jest przez ogranicznik w zasilaczu. Grzeje się PQ3 i PQ4- 4805 (zdjęcia w załączeniu)
Rezystancje:
PQ3 n1 - poza skalą miernika 20MOhm
n2 - poza skalą miernika 20MOhm
n3 - poza skalą miernika 20MOhm
n4 - poza skalą miernika 20MOhm
n5 - 32,2 kOhm
n6 - 32,2 kOhm
n7 - 230 kOhm
n8 - 230 kOhm
PQ4 n1 - 1,5 Ohm
n2 - 130,5 kOhm Ohm
n3 - 1 Ohm
n4 - 100,6 kOhm
n5 - 130,3 kOhm
n6 - 130,2 kOhm
n7 - 32 kOhm
n8 - 32 kOhm

Proszę wykonać próbę zwarciową w głównej gałęzi zasilania.

Te pomiary do poprawki.
Please do not request schematics via Email, thanks.
Nie wysyłam schematów na PW ani email.
