You plug the TV into the socket and it turns on standby, you press power, the LED goes off, the relay hits and then the LED goes back to standby and the relay hits but nothing generates matt. nothing to call.Broken zener diode (with high leakage) it is next to the eeprom and shows 5.6v on it. just change.EletrĂ´nica +ou -

It turned on and after 20 seconds it turned off by itself. smelling burnt and shaky image.Capacitor c803 (330mfx400wv) damaged.I replaced the capacitor and it worked perfectly. the burning smell was from the melted positive pole.MAX TEODORO

Sound turns on and off, vertical good correct voltages but turns off immediately, without h-sync voltage4k7 resistor r305 open... the person changes the deflector capacitor, changes the micro memory and nothing solves it... etc..Changing the open resistor r305 4k7 or diode 1n4148 that goes with it is to see that tsound is this diode together with the resistor.tvcell

TV without image but with sound dark screen!!!!After doing all the tests possible, I removed the card and tested it on another tube, which was fine, then the TV worked file, then I discovered that it was the tube that was bad.The solution found in this case was the following: I found a 15 volt dc transformer and connected the positive one to the TV filament, I connected it to pin 3 or heat and the negative of the transformer, I connected it to pin 4 of the gnd tube, the TV kept lighting the filament. and turning it off, I left it for a minute and the atv started working normally againHELIOMAR TECNICO EM ELETRONICA EM GOVERNADOR VALADARES 33-30842033
