Red color the screen has a red tinge---tried to adjust the color but it didn't do any good

Torn mine down.....and the cover over the tuner seems to be pushing down on the tuner. removed cover & washer/bolt....and it is fine. i noticed the the tab on the cover is taking the weight of the tv board. the tab was alittle bent. i am thinking of busting off the tab .......not sure if i should put the washer & bolt back on. the bolt seems to fit into the small cover.but when it is off.... the picture is much much better.

No easy fix for a TV. If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. As long as there's no burning smell, and the set is okay even when hot, after running for awhile, it's possibly bad connections on the convergence board. If you have some decent soldering skills and a familiarity with the insides of a TV, you may even save yourself a repair bill by getting some bad solder connections cleaned up. If its not the connections it could be the STK chips, or the board itself. It might also be caused by having the set placed close to another electrical device that causes a magnetic field that overtime messes with the colors on your tv. Its more noticeable sometimes after you take the device away, because the TV learnt to compensate for the effects of that field. If separating the TV from all other devices for a few days(while letting it work from time to time) doesn't affect the red tinge, you could try to degauss it manually. Some shops sell a degaussing wand that you wave around the TV to fix such problems. You can also build one yourself - tape a small samarium cobalt magnet (much stronger than your average magnet) to a pencil, then spin the pencil with your fingers while moving past the monitor. Note that if not done properly this can make things worse. Take care
