Hello c_guerrero1,

This may be the shutdown circuit activating due to excessive current I would check the Horizontal Outout transistor, and the IHVT Intergrated High Voltage transformer. These are usually the cause of these problems. I would advise getting this repaired at a TV repair shop, due to the nature of the problem and the section that may have the problem.

Thank you

Problem seccion vertical, el televisor se enciende por unos minutos, no sale la imagen completa y luego se apaga


You have a bad capacitor near the flyback transformer. Location would be 2465. Look for a 100volt 10Mf cap. Esta no bueno! Pero cuidad senor. This requires special care to remove this cap or the TV will be ruined. The circuit traces are vey delicate. Cannot tell you enough....use extra care in removing this! Tambien.....change capacitor location 2415 as it is weak. It is a 160 volt 2.2MF. Good Luck....Mathias!

TV SCREEN IS JUST A BLUE PICTURE,BUT HAS SOUND


Hi and welcome to FixYa,

Offhand it would appear that the VCR section of the combo unit would require a bit of cleaning. Specifically, head cleaning. The easiest approach is to use a VHS tape head cleaner.

The other post of "tv turns on then 5 seconds later shuts off" would be the auto-protect kicking in. This indicates that a likely hardware fault exists. Try to initially reset the unit by unplugging from the mains for an extended period. Otherwise it would require opening the unit for voltage measurement/diagnosis.

Pls post back updates. Good luck and thank you for using FixYa.

Hi,


Initially if it is near the bottom, I would suspect that somehow you have activated the "Close Caption" feature. Corrective procedure would of course be to disable/turn it off.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
