Have you tried physically inspecting the halogen lamp? The lamp can be accessed through a door at the side of the set. You need to unscrew the lock on the door and loosen two screws on the bottom of the halogen lamp housing. After loosening the screws you can pull out the lamp housing through its handle. Check if the bulb inside the housing is broken. Look for powdery deposits on the glass or lamp reflector. This are indications of a defective halogen lamp.

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

My 50hm66 will turn on,picture comes on for about 10 seconds and then the tv turns off.After it turns off flashing red led on front of tv. What would cause this?thanks jim


I had similar problem with my 50HM66 , except it would stay on for at least a few minutes. I cleaned and vaccuumed (with lamp removed) as best I could, I think it's an over heating issue. My TV is 3 yrs old, have replaced lamp once, it did it with either lamp. When I put a fan to the right of the TV so it's blowing behind it, my TV doesn't shut off. Something to try...

My 50HM66 did the same thing. Try putting a fan to the side of the tv so it blows cool air around the back. I also removed lamp and vaccuumed as best I could. I think this is an overheating issue with the tv.

I have had the same problem and after several trips to the shop I realised it was caused by humidity. The shop was air conditioned so the problem never happens there. A dehumidifier or air conditioner "solved" the problem.

Tv comes on just the sound about three seconds later tv shuts off


I have the same issue with mine and have a solution that sometimes works. I had a repair guy come to check it out and he powered off the TV so that the red light was no longer blinking, then he unplugged the TV for about 30 seconds or so and then plugged it back in. He then turned on the TV and it worked. He said it would cost about $400 to fix the issue (some circuit or something). I have since expeerienced the on/off problem (due to power outage) and now I cannot get the TV to work. But at least give this solution a try and please post to let me know if it worked or not. Good luck!

Plaid Screen


The problem is likely with your seine board or another video board. It will have distorted video/colors and you will see copies of the image in random sizes/places around the screen. If the toshiba menu is distorted it is in later stages of video, if not then earlier. More info will narrow down exacly which board. You can try reseating the LVDS cable, the computer looking one in the middle of the tv. It goes from the video board to the light engine. Unplug the tv and take off the back. The cable is usually white and has a D-type computer like connector with buttons or screws to unlock.
