I turn it on and it goes off after 5 minutes it is a cleaning to the plate and it looks good
I noticed the welds and the fleyback ones were loose.
probe and continue with the same problem.
I started to notice the tension of + b
in the fleyback where you have to see 185volt there are 135vol then the others are fine I wanted to test the tension in ths and
I put the tester in direct current and it mediates me and it disappears right away

Dude, you're wrong at + b185 on a 14-inch TV, it's over 29 so the highest is 135 volts

If you have the 503 resonator in X401, throw it across the street and put a new one on it.

It is part of the horizontal circuit, I think it is connected to leg 36 of LA7685 and the horizontal oscillator usually fails and turns off, the entire horizontal one is turned off and therefore the TV is turned off randomly and unpredictably.

friend. I think the supermiguel colleague refers to the quarzo crystal that is close to the micro

Not that, Manolo, but it wouldn't hurt to check or try another one. The one that I refer to is the one near the jungle, they are usually plastic similar to those of remote control (455) but work at another frequency (503).

And take the time, if it always turns off at exactly the same time it can be a digital fault like memory. Although it is something I never saw in that kind of TVs.

Hello Friend. check the tsh. It may be short. and check the + by filter solved the flayback pins and the choper pins and other cold welds that you see on the plate solve them. and solve the pins of the ic. vertical. If after this the fault persists, disassemble the ic.vertical aber if it no longer shuts down. in conclusion the fault is the ic. vertical that was short. regards
