It's capacitors on the three line board. difficult to replace. I would recommend taking it to A professional. It will get worse over time.

SOURCE: Toshiba 50h81 turn it self off then back on

Did you check the supply fuses to the convergence ICs? Did you check the output resistors
then i would start by replace the convergence ic first.

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.

Toshiba 50H81 manual convergence


are you sure it's yoke? these are know for bad convergence amp ic's
other wise it's a screw and glue holding the yoke in place loose the screw and try to break the glue with out breaking the plastic on the yoke, the other thing you can do is adjust the magnets which have tabs on the yoke. i would mark the position's of everything on the tube with a sharpie so you can get it back to start.
