I have a toshiba 65hm167 no red color on the screen


Your TV is a DLP one lamp does it all, not like the old projection TVs with the Red, Green & Blue CRTs. Your TV may have a bad light engine or lose cable connections.

Good luck

Funny colores and shapes on my 42" Toshiba projection TV


There are a number of possibilities based upon your description. Can you be a little more descriptive about the colors? For example, does the picture look like a 3-D one? Also, please confirm the model as that will help to identify specific defective parts and more detailed solutions.

Thanks,
Dan

Screen is all Shades of Red....


You need to remove the front tv panel, search for the screws right behind the screen and speaker area on the sides of tv. Should be four of them, carefully remove the lower have/quarter and you will find a control box, 6 knobs. Try adjusting them to clear the problem, each color has its own knob, be sure to mark their original position befor adjusting. When you find the red adjustment knob, you should be able to turn it down enough so that it doesnt overpower the rest of the colors. Good luck.

42" Rear Projection color issue


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.
