Do you normally leave this set on a specific channel...such as CNBC or BLOOMBERG tv...etc that maintains a regular scrolling image???

If so...on sets that are a few/several years old...the projection tv screens can develop what's called a "burn" or "burned image" on the screen...similar to wearing a path in your carpet from heavy traffic areas. Newer models do not have this issues...but many older ones do.

Toshiba big screen Model TZ50V60 Convergence Issue-Chips Replaced


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

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Toshiba 57HX81: Green works but Blue and Red seem to be out.


Do you still have reds? Is the image still clear though discolored? If so you ought to replace the blue bulb which has most likely failed. The part no for the 57HX81 model blue CRT bulb is TOSHIBA     23008753.

Double vision on tv


Is this a "new" set or just new to you? If new, don't waste any time on this. Return the set for an exchange. If new to you, then the problem is in the convergence circuit and if you can solder, you should be able to fix this yourself. Let me know if you wish to attempt the repair and I'll supply additional details and instructions.

Dim picture from one broken lamp??


The red CRT is most likely not the culprit. If water got on to any of the boards such as the red CRT driver board it could damage it wich also at the same time can load down voltages (200 volts etc) that can have a global affect on the other CRT's. Changing any on the CRT's by the average consumer is NOT recommended because you are dealing with a device that requires 30 KV (thats thirty thousand) volts to make it light up. Take these as warnings and consult with a technician.

The pictures colors do not line up


The convergence amp(s) need to be replaced. Your unit takes two STK392-110 Sanyo built amps. In addition all the low ohm resistors should be tested for change in value and replaced as needed... Not an expensive repair for a qualified shop. We do four or five a week...
