Check the voltages all are well during the time the TV is turned on at the time it turns off the voltages practically go to zero. and it does not turn on again I have to disconnect from the network and reconnect to enter standby. I already changed the capacitors that were devalued but the problem persists in terms of voltages the B + in sstandby 82 vol. on 146 vol. Then there is the 16 vol and the 5 vol. It seems to be fine. What I notice is that at the moment of going out it makes a noise like a deflating balloon. thanks for your help.

Friend verifies that they are not short on the board and that the TV what they are doing is self-protecting x some problem at the source in both the hot and cold stages verifies and comments

Hello Friend. First solve all the cold welds that you see on the plate by commenting on the choper and flayback pins and then check the resistors, zener diodes and rectifiers at the source. and change the small filters there from the source to new. and check the resistors and diodes that are close to the flayback and change the + b filter. and check the tsh. It may be leaking and solved the IC pins. vertical and those of the multi regulator. and those of the microjungle. Cheers

Good evening yoreparo friends, sorry for not answering, I had other jobs to do and a little rest trip, going back to the subject, I checked how you told me the polyester capacitors and I found one with code 124J 400v in position C425, which is 120nf. devalued that barely measures 63pf. Tomorrow I will look for a new one or in good condition and try the TV if it happens. See you tomorrow, colleagues. Thanks for the suggestions..
