Toshiba TP55F80 convergence problem?

I have a Toshiba TP55F80 that I think I purchase in 96/97. The set has been great with the exception of recently the magenta(red/pink??)color slightly drifts out of place for a little while and then snaps back to where it should be only to repeat this scenario over and over. Can anyone offer suggestions on a fix for this problem

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

Red light keeps flashing on toshiba theatre. How can I fix it?

on the older sets it is a short and usually in the convergence circuit, the way to know is located the convergence chips and unsolder both from the board (18 pins each) and if set then comes on (WILL LOOK BAD) one of the two chips is bad and both need to be replaced----should be stk-392=110 chips.

How to fix the convergence on a toshiba TP55D81 tv using the remote control

The convergence is adjusted with the remote by entering a tech menu and adjusting there====if convergence is really bad adjustments are not going to fix it.

The set should have in customer menu a limited convergence adjustment with up to nine points where you can adjust---if it will not adjust there in some way----convergence circuit needs repair.

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.

Gun problem

Bill, the picture tells the story, you`ve lost convergence, either the convergence IC`s have failed or theres a slight chance that one of the convergence plugs got partially pulled out when you moved the set, of course the latter would be the easy fix, remove the back of the set and check all the plugs by pushing down on them or of course if you see one laying out of the plug just plug it back in. If the IC`s have failed or possibly the solder is broken on the IC`(s) and you are proficient with a soldering iron you can try re-soldering the pins, be prepared to lay on the floor for awhile there are 18 pins on each IC. check the plugs first (unplug the AC cord first), let me know if you know how to solder & unsolder and we`ll go from there, not much room on here to type in everything in one reply.
