Question about Toshiba 43H70 43" Rear Projection Television

Toshiba 43H70 HD Projection TV

Hi, Hope you are doin well. Been having some trouble with my TV. Hope you can help me. The bottom third of screen is curved upward and the colors seperate as it gets to the center of screen. I go to the convergance menu and the green cross is above the red and blue and is tilted to the left. Took the green magnifier lens off and put screen back on. That fixed the curve or arche but of course the green is not focused. Then I covered the green gun and the picture is good but the green now is ommited making the picture very red. Does this mean the green/center color gun is bad or the magnifier lens? When you have a moment please let me know your thoughts. I would be very greatful for your help. Thanks a millon........Andre the old heavy chevy guy.

It sounds like your horzontal control is bad. It requires a new circuit board.

Picture

Depending on the manufacturer of the cable box, there will be a menu somewhere regarding aspect ratio using the terms - cropped, zoom, and a few other terms as well. You probably want cropped, which will cut some of the sides off, but you wouldn't miss the picture as a whole when view at full screen. Hope this helps!

Toshiba 43" Rear Projection tv (Just show's Blue Screen)

Hi Chris,
It sounds like you have a tuner problem. Usally the set will turn blue if there is no signal to the set, which is first generated from the tuner. It could also be the processor on the main board, but I would look at the tuner first.
Good luck and I hope this has helped

Your tv has a convergance failure. the convergance ic's need to be replaced. Upgraded part # STK392-150 or STK392-160. Both ic's should be replaced to prevent future failure of other colors.
