Toshiba 57h84 tv lightning damage

SOURCE: My five year old Toshiba 57H84 rear projection TV

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!

SOURCE: Will not power on.

Your blinking red power light is indicating a problem with the set. It has read an error code. With my experiance with Toshiba I found that a dead set or blinking red light can be a whole bunch of diffent conditions. One common problem though, and I would check this first, is your convergence circut. It is very common that the the convergence IC's themselves and or some resisters in that circut have failed. Also check all the pico fuses on the power and sub power supply's. Hope this helps and good luck

SOURCE: I have a toshiba tz50v51 projection tv. the red power light is on

It could either be due to the convergence Circuits ( If the Power Indicator Blinks) or the power deflection board if it doesnt blink. I have a source for parts if you would like the link.
