TVE lg model cp-20j50 turns on, oscillates for a moment and turns off, it had a fault in the horizontal and was working normal then it did not turn on anymore and from there it has the fault that it is in stand by and it turns off after a few seconds, if Anyone have a possible solution or know about this fault would appreciate a solution. regards

Hi. If it takes a few seconds you can measure tensions. The most important.
Vertical.
Chroma
Scrin
ABL
And comment a little and also make a report of everything you controlled. If you reviewed welding in general at least.
See what it does on the screen or what it manifests if you still have the scrin

Not long ago, the TVE only turns on and off, does not reach 3 seconds and the voltages of the + by main filter remain stable the filter in 170v and + b in 110v

Your problem could be in the jungle, I had that same problem before with one of the same brand and I had no more to return it, I was very expensive to get another jungle, I hope it is not that friend

I already managed to turn it on was a resistance, now the problem is that when I change the channel CH- it turns off ...... it drives me crazy

[b] I commented that resistance was wrong. If when you want to change the channel the TV turns off. Change the buttons. [/B]

It is a resistance that is next to the flyback, I do not remember the reference but it was 10kohm it was black and did not mark anything
