Hi Guys, Good Day
This Lcd I had from my friend with the problem of coming ON and goes off after few seconds. I manage to bring it to life after changing the Pulse width Modulation control ic TL494 in the inverter circuit. Picture is brilliant but no sound. I noticed one of the ic U9 EZ718 has got pin hole in the middle which tells me that it must have been overheated for some reason. But it is difficult to tell if this ic has got anything to do with Audio circuit wirhout a circuit diagram. All the other functions seemed to be ok. Could anybody please guide me to the Audio components if you had ever seen this fault. Your help will be much appreciated. Regards
Jeet
