I have a 56" Toshiba DLP TV, yesterday evening while watching the CNN news we have heard a cracking sound and the video disappeared, the screen went black. The audio was OK, but the two pilot lights on the bottom right of the sreen were flashing red first and then green. When the red light was flashing, the audio comes on and when the green light was flashing the click sound was heard. It kept doing that untill I turned the power off. What could be the problems? Thanks a lots, Xay Bounnapha

Hi when was the bulb last changed as when the bulb goes it will do this. at the back of the tv is a panel, it will have vents an a sign saying something like bulb on it the bulb is in there and there is a screw holding this cover on and inside is a clip that holds the bulb in place, remove bulb and check it for its colour if its black then its blown and you just need a new one. if its damaged in any way replace it and do not touch the glass.

SOURCE: TV Picture Goes Black

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions

Thats the error for lamp driver error. Which means the Ballast is most likely defective. You can get the replacement ballast for your model at the following link which comes with installation instructions.

I was watching my Toshiba 56mx195 DLP tv and heard a popping noise and the screen went blank but the sound was still on, is it the lamp or something worse?

You are correct in this assumption it is more than likely the lamp that blew after too many hours or getting to hot.

My 65 inch flat screen Toshiba tv has tiny white spots all over the screen. Can I change anything to save the tv? Any help is appreciated.

This is an easy fix, just change the DLP chip.
I bought one on Friday and it got here yesterday, I followed the video instruction on Utube. I spent maybe 1 hr, because I kept going back and forth from the tv to my PC to watch the video.
The chip is soooo easy to replace, and only cost about 150 bucks at shopJimmy.com

I have a Samsung 50 inch DLP - I heard a pop and the picture immediately disappeared. The 3 lights were flashing on the front which according to the book said it needed a new lamp installed. I ordered it,...

Sounds like the color wheel may have also gone bad. I recently saw a 56" Samsung where the bulb and color wheel went at the same time. The color wheel could produce a crying noise while trying to spin up.

Samsung HLR5067W goes from a normal picture to snowy green color

Greetings!

I hate to be the bearer of bad news, but it is not something that has a quick fix. Without inspecting it myself it is impossible to say, but the last three of these that I have seen have been bad digital boards and can be a real bear to change, even when you have experience.

I would get slightly different video symptoms when I would switch between the coaxial input to the component input to the HDMI input. But in all cases my on screen display and menu were anomally free. Hope this was helpful, even though I don't think it is something you should attack yourself.

Good luck!
