Question about Toshiba 43H70 43" Rear Projection Television

1 Answer

43H70 picture wobbling

On occasion, the picture appears of wobble rapidly. The picture also lookes curved at the top and bottom of the screen. This particularly noticeable when you are viewing a widescreen movie when the black are meets the pitcure. This wobbling occurs for a while and then it will stop but it may happen again. There seems to be no pattern. I have met with 4 TV repair people and no luck yet. Also, I live in Baltimore County, Maryland. Do you know of any repair places that fix Toshiba. Can anyone give me a suggestion. Thanksabunch.

Possibly leaky cap in power supply,look for a 1000mfd/16v cap in on near the b+ supply and also cold solder connections.

If the entire screen is curved, and it is not taking the whole screen, then you have a vertical deflection problem.

If the colors are double and do not match, with lines of different colors around pictures , then you have a convergence problem, often caused by a faulty convergence board.

The curving effect can be a side effect of bad convergence, or you may have both problems at once.

Unless you are a TV repairer yourself, better calling technical support. Usually you can ring the number listed on the owner manual.

Three curved lines have appeared approx. 6" up from the bottom of the screen. Is this a simple fix .... maybe as simple as replacing a bulb?

Are you saying that the whole picture is gone and all you see on the screen are 3 curved lines near the bottom, or is the picture there but 3 curved lines are over the picture, or is the picture there but the bottom of the picture has curved upeards?

Arched picture at bottom seperating the green and red

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.
