Question about Toshiba 57H81 57" Rear Projection Television

1 Answer

Pip board bad

My Toshiba when you first turn it on the picture is all mixed up, you can not see anything way out of focus, after its on for about 3 to 5 min it becomes clear. A local tv repair man told me he has fixed the problem on others, he said it was the pip board, does that make sense? and if so can i buy on and install myself?

My picture in picture isn't working?


Most of these sets have two tuners--one for main and one for PIP.

If main picture works fine but PIP is bad or Green? either the PIP tuner or the PIP board is bad---these were known to have the PIP have problems but it was more rare than their sets made before it.

My 57" Toshiba projection TV recently started having picture problems. The picture is distorted and wavy. The picture on the PIP screen is fine. is this a common problem and is it fixable?


First bypass the cable box and hook the tv directly to the cable to see if the problem goes away. if the problem persists you possibly have a bad input board.

if you have already adjusted the focus pot on the line o/p transformer (a small transformer with a lead that has a plastic cap attached , and is typically clamped onto the top of the crt/tube BE CAREFUL DONT TOUCH CAP WHEN TV ON VERY HIGH VOLTAGES)
also could be your crt/tube is bad if so then scrap/recycle

Whats a quick solution


The problem may be related to bad capacitors on the PIP module. This is a commom fault as vertical sync runs through the PIP board and this is the symptom of the pip board having bad capacitors the TV rolls.

Rolling picture could be a pip module problem as both horizontal and vertical sync goes through the PIP module. These sets have been known to have bad caps in the pip board causeing loss of vertical sync.If you need any more info let me know.

PIP function


The Main Picture will eventually go out or at least become distorted. Generally the PIP circuit can be repaired by replacing a couple of capacitors. Probably a job for a Pro but it will need to be done at some point.

Main screen color seems overmodulating. PIP subfeed color fine. White like under black light.


rule number one about all vs chassis with vertical can pip boards take them out and throw them away i could fix one but you couldnt beleive me and it wouldnt be worth your while do a search on your modle number until you come up with instructions on how to add two caps to the pip board connector to bypass it until you do this you are wasting your time Mitsubishi ... we're still building Zeros
