Good night. I have this TV which turns the standby LED on and off several times and does not turn on. The voltage of + b is 140 but the tsh does not occur. I measured it and it's fine. Change the driver driver and nothing. Labfuente connect it to a lamp in + b and when the voltages turn on they rise and fall together with the LED and the relay that opens and closes until after a few seconds all the voltages stabilize but the horizontal transistor still does not oscillate. The rest of the voltages of the source are according to the 15 audio diagram that are good and 10.5 where I have 8v. What calls me attention and is making me noise is the rise and fall of tensions at the beginning. Can someone help me to know what voltage should feed the jungle and in which pin? Any help is important. Thank you very much. [Img] 9 [/img]

greetings friend. Something similar happened to me recently with an LG. I don't know if it's the same solution soon, but I'll comment! I had almost the same symptoms and what I did was change the flyback and it worked. try this solution to have how it behaves and comment on how you are doing, in addition to this change the filters of the source and those associated with B +, also change the tsh, the filters and the tsh they recommended it to me only as a precaution Greetings from Colombia

Dear colleague from now very grateful. indeed the fault was in an electrolytic capacitor in the + b line. This chassis has 220x160 filters and a smaller one. I changed it and holy remedy. Hug from San Rafael, Mendoza Argentina

I have the same TV. With the same problem, it has the two 220x160 electrolytes in good condition, but I can't find the other one they say is smaller, I would appreciate if you can specify, greetings!

Hello friend, I followed the track of + B to the flyback and you will meet him.
