Turns off after 10 seconds after being turned onOne of the channel change switches was not working, I replaced it with a new one and the TV was normal, then I realized that tsound was a resistance between the two terminals of the switch. Note: whenever you notice that a device no longer changes the channel or increases the volume on the television panel, change the contact switches as they can create internal resistance, causing very complicated defects.fabiusmax

No image with audio/screen offBy slightly opening the skew you can see the softly reddish screen with return lines (retraction)The cause of the problem is the open 100k 3442 resistor, replacing it and readjusting the skew, the TV returned to normal operation.WAGGUINHO
