előre is köszönöm : epityu
Üdv Mesterek!
A készüléket tunerre kapcsolva a kijelző belassulva elsötétül. AV módban hidegen 1-2 percig bírja aztán ugyanez a helyzet.Amit észrevettem , jel nélkül a kék display megmarad AV-n de, tunerről jel nélkül is elsötétedik,a t-con leáll...Egy donorból (törött disp.)a maint(PE0250) és a scaler panelt (PE0251) cseréltem , semmi változás.Sajnos T-con az nincs másik... T-con hiba lehet? /V420H1-C07/ Esetleg valaki találkozott már a jelenséggel ? (A lengyelek igen, de nem írtak megoldást) Köszönöm a segítséget.
Kedves Mesterek!
Az adott TV közepén egy piros hátterű felirat van: CI Plus key Fail!!!
Nem akar eltűnni, csak a menü takarja.
Szoftver frissítés megtörtént, semmi változás.
Minden ötlet jól jön.
Köszönettel.

Subject: Request for dump file – Toshiba 40L2434DG (L2300 Rev 1.03A.01 / W25Q64)
Hello,
I'm looking for the EEPROM dump (.bin) file for a Toshiba 40L2434DG TV.
Mainboard: L2300 Rev 1.03A.01
Flash memory: W25Q64
Panel: UNV4031-01Y
The TV is stuck during boot ("Do not power off scan") and shows a flipped image. I have a CH341A programmer and I’d like to reflash the SPI memory to fix it.
If anyone has the correct .bin dump, I’d be very grateful if you could share it.
Thank you!
Best regards,
Andrea
