How to fix

if picture is 3d looking with colors skewed etc it is convergence--tell me as much as possible as if model listed is correct I know it well.

It is an internal problem. In my opinion, i wouldnt handle this specific problem myself, but take it to a tv repair specialist. Fisrt, i would follow the trouble shooting manual, then all customer support.

Due to persistent on/off some components inside the TV might have become faulty, leaky. It can also be due to lose contacts. This might need attention by a qualified service technician.

If its disorted, zig zag looking, etc your hypermodule has gone south. You can get a repair kit on www.TvRepairKits.com to fix this yourself.

It's possible there is either a codec problem with your computer player. I would recommend trying a player such as VLC Media Player, to see if that works. If that isn't it, what kind of TV's are you watching the video on? Are they "tubed" or flat screen? If they are tubed, you wouldn't be able to see the line at the bottom like you do when you play the video on the computer.

Well you can do it yourself if you have experince unsoldering and soldering.. change convergence amplifiers .. look for 2 parts with STK392-XXX .. depending on model number the 3 xxx will be the last 3 digits on that part

This could mainly be that your scart lead could be loose at the tv end or it is loose at the console end, also see of the disc is not smudged or scracth sometimes this is a cause, it may be your tv is broken instead of the console, if it is a gameboy you may have broke a pixel line.

colors all messed up, looks like 3-D ??   convergence amps and possible a few resistors are bad

Practice visual acuity technique! Examine chassis,solder any/all bad connects,re-assemble,try again.If that does not do it,you might have a small break in pcb==gently flex board,try to isolate area.Above all else,do no harm!!
