Blurry at first then when it warms up the distortion goes away


Most of the Toshiba sets of this age had problems with a board inside that gives lines/noise left to right for several minutes and then clears up--as time goes on the warmup takes longer and longer---bad Hyper board with about 10 tiny surface mounted filter caps that dry out.

Part is not available and two options--either have a shop repair it or try it yourself---takes above average skill to remove board and replace all ten caps.

Shops will if they will attempt this usually get over 200 for the repair.

Upper left corner is distorted and neon green


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.

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 from the link below.

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 - 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.

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 solution

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

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!

When i turn my tv on after about ten minutes its powers it self off


hi, well unfortunately your unit has developed, a fault, a component is heating up, and failing this is probably due to a bad power supply, and you see the unit detects a fault, with the thermal component changing value and then the unit shuts down to avoid a fire or explosion. faults such as this are VERY hard to determine, it may be worth while waiting until the fault becomes "Hard" and then get a firm "Quote" for a repair.

Hi I have a sony KDP-57XBR2 television set and the


I had the same problem in blue. I took the right front speaker cover off (pops off) and the access panel on the right side 2 - 4 screws. In the upper right corner is a black plastic box with 2 rows of 3 adjustment screws. All I did was turn one of the "screen" screws (not the "focus" screws). Hope this helps. May only be a temporary fix, but good luck...

Sony KF50WE610 Vertical Blue Lines Across Screen


the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!
