Hi, This is a convergence problem and you can set it right by changing the STKs. It is a professional job and i have knowledge of people who ruined their tv by spoiling some miniature surface mounted components close by. You may need to look at pico fuses too. I would say seeek professional help if you not comfortable working with electronics. Check out at www.fixurtvs.com,
It sounds like you are having a problem in the conversion circuit. The outputs IC’s for that circuit have failed and are need of replacement. The average cost is at least $450 on one trip. Call an Authorized Service Dealer for repair and estimate.
The conversion circuit is the circuit that aligns the picture.
this is called a "collapsed" picture. it is normally a simple repair for a tv technician. simple for them but almost impossible for the average consumer. if the set is fairly new and not under warranty it might be worth your effort to take it to a tv repair place and get an estimate on the repair cost and go from there. if it is an old set it is time for a new one.

I have a Toshiba HD LCD tV, model 37AV50U. the screen is black. I still get audio and can change the channels but the screen stays black. It doesn't even show the menu box. Is this something I can fix myself?
