legionaru Posted February 10 Share Posted February 10 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. IMG_20210210_111906_882 Quote Link to post Share on other sites

Costica Tv Posted February 10 Share Posted February 10 (edited) 4 hours ago, legionaru said: Domnilor...probleme! Nu găsesc memoria... Pai daca am postat U302=24C32, e logic ca eepromul 24C32 este marcat pe placa cu U302.... 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 Edited February 10 by Costica Tv Quote Link to post Share on other sites
legionaru Posted February 10 Author Share Posted February 10 Când am văzut că nu pot descărca, am montat o memorie goala; a flash- uit ledul puțin după care a pornit, dar cu aceleași simptome... Quote Link to post Share on other sites
