I HAD exactly the same problem. It is a connection problem and not a Sony problem. The fact that other sources show a good picture is the critical clue. I found a loose connection on the rear of my Dish Network receiver. I hope this works for you. It did for me.

Color looks white washed!!!


there are in the older rear projection sets lens for those that do not use a lamp for a light source.

In the older sets there are three large black lens that can be seen and reached with the rear cover off---if there clean them as they are the light source in those sets and if dusty picture will look dull and darker than it once did.

If in doubt shoot me a model number.

Toshiba 50H81 very dark, blurry picture on all inputs.


check if the problem looks zig zag looking or it its not present in the PIP window. If so this may be an issue with the hypermodule - you can google TV repair Kits to find parts.

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!

Toshiba Rear Projection TV picture color is now a greenish hue


Hi, I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website:  

http://lgknowledgebase.com/kb/index.php?View=entry&EntryID=3229 

If you are not able to adjust the convergence using the remote you will need to replace the convergence chips. 

Typical Symptoms

1) Convergence menu does not work for one or more colors.  
Such as: Red moves up,down, but left or right fails. 

2) Screen is bowed looking.

If you have one or more of the problems above you need to replace the convergence chips. You can get a kit and instructions from www.TvRepairKits.com  

Hope this helps :)

Hitachi 50 Rear Projection color TV


the easiest way is to turn the color all the way down to zero. Then notice the overall color of the screen, if it doesnt appear as a good black and white picture you will have to adjust the screens. To do that you have to remove the speaker grill cover and the small access panel, then depending on the chassis you will see a small square with 6 dials on it 3 on top and 3 on the bottom it will have screen stamped on it. adjust those 3 untill your screen appears the best black and white picture as possible. Now if your chassis only has 3 dials on the sgaure control box those are focusdont adjust them. . then the 3 CRT boards will have the dials you need adjust those for the best black and white picture. when your satisfied that you have a good black and white picture. then turn your color back up and adjust the tint.Let me know if you need more assistance.
