Toshiba projection TV TP55F80

When I first turn on the set, it crackles and jiggles. Then as it warms up it will pop occasionally. The color is fine. Is this the tuner?

When I turn on my rear projection tv & the tv is cold the color will float,the picture will shake side ways for about 15 minutes.what can I do to fix the proble?


You did not provide a model so I am not sure of the type of set u have. Wheather it be CRT, LCD, DLP or LED. My 1st guess regarding "color float" is possably the convergence board/section of your set. And the warming up issue could be the result of cold solder connections and/or faulty caps on 1 or more circuit boards. Search your model number through the internet for clues.

There was a slight squealing and then a loud pop and now no picture. We have sound but no picture. Toshiba 65" rear projection set.


Sound like the color wheel exploded. When this happens the tv will not let it turn on, now for the real bad news,,,, Toshiba does not supply just the color wheel, you will have to replace the entire light engine for around $450.00 to $650.00

WHERE CAN I FIND AN ORIGINAL REMOTE FOR MY TP55F80?


The problem is probably that one or both of the STK convergence chips have failed. These control the convergence coils around the red blue and green guns and are the most common cause of sudden convergence problems and the protection circuit shutting the TV down when turned on.

I can post details of how I replaced these on my Toshiba 40WH08B. Yours should be similar.

Tp55f80 tv. to much red on screen


You have a convergence failure. It may be possible to simply re-solder the pin connections under the convergence output ICs as they have a tendency to develop cold solder joints which cause intermittent mis-convergence. If the solder connections are good, then replacment of the ICs will be necessary. Expect to pay $350-450 to have a toshiba servicer fix this.

Toshiba TP55F80 convergence problem?


check the convergence chips for bad solders or even the crt sockets, I would lean more on the ic's and surrounding area.
