There are some boards in the tv that plug in (push down) have the power off and unplugged have a look around, and see if any boards have come loose, stay away from any thick red wires (EHT) DO NOT PULL At the Gray Rubber Caps that go to each gun (tube) RED GREEN Blue, this can carry a heavey charge even if the tv is off and has been for days, regards mark

My five year old Toshiba 57H84 rear projection TV has a pink tinted screen when you first turn it on, then after it warms up, the colors are all fine but then the picture has evenly spaced blue tinted...


Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

Can not align color dirvertions on test screen


I think you need a remote to use the convergence features of this set. Does it have an auto convergence feature? And does it work?

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.

INSTRUCTIONS:
  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.
