Üdv!

Adott ez a Soundbar vezeték nélküli mélynyomó része, nem akar működni, semmi életjel,készenlét sem világít/villog rajta. EBR89625801 táppal egybeépített alaplap van benne, mérésre tápfeszültségek rendben, táp részen, és az alaplapi DC-DC konverteren is. Erős a gyanúm, hogy az alaplapi SPI Flash memória lehet a hiba oka, WIC602: MX25L8035E a típusa, ehhez keresnék tartalmat.

Köszi!

A leírásban ott a link a tartalomhoz.
I apologize for the wait, the long video, and my even longer finger nails, haha. Covid put me a week behind! If this helps you, please consider donating to fund my project haha :P *update* If you are getting error code 0000E000 during the verification process, I believe it is because the chip has data there that is unique to each board. I have now fixed 4 boards and each one gives me the same error. The only board that verifies correctly is the board that I took the firmware file from. All 4 boards still worked after that error, so I believe it is just a serial number or something like that. Sorry for that not being clear in the video! Need help?

Köszi!

Hogy tényleg működik-e azt majd én próbálom ki gondolom... Vagy csináltál már ez alapján?
Érdekesnek találom, hogy ez a CH341A tud In Circuit írást...
