Television and Home Theater

I have a Samsung 42HDTV WideScreen and somehow my convergience is messed up on my TV, on the right side of the screen it has a red shadow like the red bulb is not centered..I've tried to fix it in the controls but it wont straighted ..is it possible to fix this myself or must I have it repaired..I'd like to try and do it myself if possible, (Im broke at the moment). Any suggestions would be appreciated..Thnx

our remote control will not turn our television on or off or work the volume(or anything else). it is not the remote because we use it to work our satelite also. we also have a second remote to work the t.v. but the t.v. will not respond to it either. in order to turn the channel or the volume up and down we have to use the buttons on the television itself. can anyone please help us? the t.v. responded to both remotes as of just a few days ago but will not now.

My one and only TV is having problems and I have no money to go fix it. I am hoping I can do it myself. Here is the problem. I have a 20" screen Toshiba TV and when I first turn it on I only get maybe a quarter of the screen, then after about half an hour (if it doesn't turn itself off, I now know I have to have my DVD player turned on to keep it turned on) I can get a little more than half the screen to come in. Please any info or help will be much appreciated.
