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.

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.

Toshiba 42PW33Q rear projection gone blue

OK to help assist everyone having the BLUE HUE and CURVED LINES Issue on their Rear Projection HDTV no matter their model. Here are the steps to take. The first thing to check is the FOCUS BLOCK or G2 Focus Transformer or CRX F-Pack. I have replaced mine, however it didn't resolve the issue. I am onto the next item the CRT Board for Blue (Which is the board under one of the three color lamps inside your tv) Please see photo below (if photo is not large enough below go to link to review notes as well) If the CRT Board is not it, then the next step will be the Signal Board which is a larger board in the back. In a week I will have a picture of both.

  1. Remove the outside cover
  2. Remove the wood plank/panel
  3. In the front is the G2 Focus Block/Transformer, while set is on turn the top 3 knobs till the screen goes black/dark grey.
  4. adjusting the colors till you receive the desired or normal color/picture.
  5. Once you have received the proper color/picture tap the side of the Focus Block.
  6. IF The colors go out of wack again and the blue comes back strong then this "CAN BE" the Focus Block.
  7. NOTE: IF the color stays stable, then you problem is resolved and you do not need to replace it.

Replace the G2 Focus Block aka Focus Transformer, if Hitachi it's called a CRX F-Pack. This item will cost about $50. Not expensive. You will likely need a soldiering iron. DO TURN OFF & UNPLUG THE TV WHEN INSERTING ANY METAL OBJECTS INTO THE TV!!

FOLLOW THE PHOTOS/DIAGRAM in link below for assistance in the above instructions. I will post my next process since it was not my Focus Block that was an issue.

Mitsibishi 50" vs50607 convergence?

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
