hi guys,
received the board with c7800 short to ground , removed it and replaced with a good one and it worked fine for few hours the it goes bad again , this has happened few times , can you suggest what can that be ? i will update about the voltages on it later.
thanks

hi , thanks for the response , i have just checked the schema , you are absolutely right , there is no ground to it , it is connected to the resisitors and q7800 , actually every time it stops working the c7800 shows continuity like a fuse as it was a caps so i didn't bother and thought it was getting short to ground and replacing it makes it work for a little while . i did not check the resistor values around it . what do you suggest , is it happening because of faulty q7800 ,i will appreciate your advice , thanks
