Television and Home Theater

I'm not really sure how to explain but te screen is dull on te left and right side there's just a 6" or so column of the screen that is actually the right color. The dull portion looks kind of like a glare. I have pics but can't post them from my iPhone. But if you leave your email address I'll email them to you. Thank you so much. A tv tech said maybe dmd chip or light motor I've already tried a new lamp and didn't solve it

SONY Trinitron Model KV-XF21M65 LED blinks twice and TV has no sound and picture. I know the fault is due to a high currant leakage in one of the power supply circuits, causing the overload protection circuit to shut-down the TV.

The Horizontal o/p transistor C4927 is OK and no other components is faulty in that area. I did a thorough clean and resolder job.

But without a schematic diagram, the fault finding will be an uphill task looking for a pin in a haystack.

the other night my TV (by itself) turned the volume up as loud as it could go. when we used the remote to try to turn it down that didn't work so we used the button on the front of TV.It turned it dow but as soon as we lifted our finger it was right by up as lound as it could go. we finally had to uplug it. Now when we plug it back in all we get is the green blinking light. Help
