Question about Toshiba 50H82 50" Rear Projection Television

Toshiba 50H82 blue arcing?

I have a Toshiba 50H82 rear projection TV that is just five years old. The other night I was watching TV and a blue arching light stream appeared which distorts the lower part of the screen. It also causes a ghost blue shadow when either numbers or letters appear at the bottom of the screen.

I already bought a new Samsung 47" but would like to attempt to fix the Toshiba on my own. Any suggestions?

    For us novice, what is a CRT deflector and where is it located?



    Can it be changed, cleaned or what?

    What would be causing these red and blue shadows? The faces are not distorted but they have this red and blue running thru them.

Color shadows on numbers or letters indicate a possible convergence problem.. might be a crt deflection problem.

    crt is the "picture tube" what you need to look at is convergence amps..the crt is something not for the novice. Convergence is ideal set up at the factory. in a special mode. usally there is two cuicit called ic that go bad. or in your case mabe 1. since its only the blue bad.

How do I know I need a new projection lamp? My tv


This set does not have a lamp. It has 3 crt tubes that converge to create a color picture. The convergance is off a little causeing this affect. Go into the menu and look for convergence or magic focus. You can download the owners manual from Toshiba website to do this. You will need the remote that came with the set.
