You might have burned out the red color crt. In projection TV's there are 3 CRT's (one for blue one for red, and one for green). If you have the other 2 colors but no red I would assume this is your problem. You should be able to get it fixed for around $150.

I have a toshiba tp50h50 rear projection tv and their is a blue shadow behind the words and makes the words a little blurry


Sounds like you need to do a color convergence. If you still have the owner's manual, it will give great detail on how to do this. The convergence menu is accessed from the video menu on the tv.
The tv has three color picture tubes, red, blue and green. The convergence alignment adjust each tube so that color from each tube overlaps each over to create a white image on the screen. Most tv's only allow you to adjust the blue and red colors.
Convergence should be performed each time the tv is moved and at least once annually.

I Have a major convergence problem. It is a 55 inch Toshiba ColorStream Projection TV(tp55h95). It was fine until we moved it into the other room, and now it's like the color is bending at both sides of...


Color arching.... Ahhh Yeah they eventually do that after a few years. Good news is all you need is a screw driver and some of your time and patience.

The color gun is a small box with 3 screws on it. (Blue, Red and Green. Turning the screws (Slightly) on the gun will get rid of the color arching. I had blue arching on a sony 65" Rear projection a year later it was red arching if you leave it long enough it will be arching and in and out flashing of solid color. Whole mind trip you don't want to venture on.......

The box on my sony was in the very front of the tv. I removed the front speaker panels and accessed it very easily. The hardest part is getting the front panel off. Yours may be in the back.

Best regards and Semper Fi...

Trying to manually fix color convergence on Toshiba 57H81


The convergence ICs and the six 1.8 ohm 1watt resistors need to be replaced. You can get the convergence repair kit for your model at www.tvrepairworld.com which has the Two Convergence ICs and the six resistors plus the CD with instructions on how to do the repair.

57HX81 projection tv,color is mostly red and picture is double.


This is a convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$300

If the convergence on one or more color does not align using the convergence setup procedure, that means that one or more convergence ICs must be replaced, that is the reason why you get bad picture.

That means that the convergence ICs are bad and must be replaced, the job is about $200/$300.

Toshiba TP50G50 Theaterview picture is double with red color only


Your alignment is off. Go to the set up menu then convergence. hit right and you will be in the convergence menu. select the color that is not in alignment. The green line does not move. if blue and green are lined up the line will be cyan. if red and green are lined up the line will be yellow. when all three are lined up the color will be light. Best of luck!

You need to take the Toshiba remote that came with the machine and go into a menu area that deals with convergence. Here's what the manual says:

This TV used 3 separate TV tubes, red, green, and blue. The R, G, and B images are pojected onto the screen wheree they converge to form a full-color picture. You can see a clear picture only when the three images converge correctly. Corvergence my drift over time, or if yo move the TV. I you can see clear images on your TV screen skip this procedure.

Make this adjustment only after the TV as been on for at least 30 minutes.

Press the TOUCH FOCUS (auto convergence) button on the front of the TV at the bottom.
The TV will enter into the convergence mode and adjust the converge automatically (that's what it says.)

TO ADJUST IT MANUALLY:

Press MENU, and the press < or > until the PICTURE menu appears.
Then press UP or DOWN to highlight CONVERGENCE.
Press < or > to display the Center Convergence menu

There's a lot more the book says, but, I can say from experience that you just go through the different sub areas of this menu and converge each color separately, and bingo, it's fixed.

Good luck.
