LG imagine intunecata

Recommended Posts

Model:  Lg20lc1rb

MB: cl-81

Sursa: yplm-m004b  rev1.0

Display: ht201v01-101

Defect: imagine foarte intunecata, (lămpile in Nr de 6 buc, se aprind corect) atât pe tuner cat și pe Av, osd-ul se vede absolut normal.

Am găsit un condensator umflat, bineînțeles, i-am schimbat pe toți din sursa, dar defectul persista....

Fara semnal pe tuner, se vad pureci, la luminozitate normala.

Tensiunile sunt ok.

O sa atașez poze.

Domnilor...probleme!

Nu găsesc memoria...

 

Pai daca am postat U302=24C32, e logic ca eepromul 24C32 este marcat pe placa cu U302....:rade:

Trebuie sa rescrii doar U302=24C32 (setari alterate in service), nu ai treaba cu flashul, in asta e softul tv-ului cu care nu ai treaba !

Eu nu am ramas decat cu un singur punct la rusi si nu pot sa te ajut cu descarcarea dumpului U302=24C32
