Question about Sylvania 6427TE 27" TV
TV DOES NOT STAY ON. AS SOON AS YOU TURN IT ON, IT TURNS OFF AUTOMATICALLY. CAN THIS BE REPAIRED? THIS TV GETS THE BEST PICTURE AND AN INCRDIBLE STEREO SOUND IN IT WOOD CONSOLE.
This problem sounds like a short inside the picture tube itself unless a driver transistor failed that drives the red gun in the CRT. You may have to take it to an authorized repair facility if the picture tube is still in warranty.

Intermittent problems are the toughest to track down, but usually have one of two root causes. Cold solder joints are an intermittent contact between where a component (transistor, etc) is mounted to the circuit board and the electrical contacts of the board itself. The other cause is components which break down under heat. Either way, if your not much on troubleshooting, have a TV shop service it, it can be easily repaired.

This could be a High- Voltage shutdown circuit problem. The reason it will stay on longer with a bright picture, is the high voltage is slightly reduced, not allowing the shutdown circuit to shut off the set. But I believe your problems to be in the shutdown circuit.
