Question about Toshiba 55H70 55" Rear Projection Television

1 Answer

55HX70 The red lamp on the tv was way out of whack as far as doing the convergance. Then the tv shut off, red light still blinking on power button. So i unpluged and plugged back in and when tv came back on it was ghosting and had all three colored lines waving from top to bottom. after reading here I concluded that the IC's need to be replaced. If so is that why the tv shuts off? or is that related to another issue i may have? thanks Rob

When i turn on the tv there is no sound only clicking sound and no picture. then it atomaticly turns off. also the lamp light flashing red? not sure what is wrong.


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

Red power lights blinks and tv will cut off. sometimes after you unplug it it will come on after about 10 min. now it will not come on unless you unplug it and then it will work about 5 min and cut off...


depending on the age of your tv, this appears to be a common issue. Blame it on the ballast board. your ballast might not be able to provide the lamp w/ enough voltage to keep the image on for longer period of times. or it could simply be that you need a new tv lamp.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

It's in standby mode.

Do a reset and see what happens

While holding down the reset button on the remote
Press the power button on the tv
(The tv will turn itself off the back on)
Now release the reset button

It sounds like the lamp needs replaced.

Toshiba 55hx70 projection tv problem


How many times does the light blink? It should blink a number of times, pause then blink the same amount then pause. Try to count the blinks then let me know. Also how long does it run before shutting down if any?
