Question about Toshiba TP43H95 43" Rear Projection Television
HAVING A PICTURE PROBLEM. I TURN ON THE TV AND IT WORKS FOR A WHILE, SOMETIMES A FEW HOURS SOMETIMES LESS THEN THE PICTURE TURNS OFF BUT THE SOUND REMAINS. THEN I WILL TURN IT OFF FOR A WHILE THEN TURN IT BACK ON AND AGAIN SOMETIMES AN HOUR LESS OR MORE BUT THE PICTURE WILL TURN OFF. I WOULD LIKE TO KNOW IF I CAN FIX IT CHEAP OR IF WOULD IT BETTER JUST TO BUY A NEW ONE. THANK YOU, PHIL
Take out the bulb (back left hatch door) look to see if the element inside the bulb is broken or blackened - (replace bulb) if the bulb looks OK then it's the ballast that fires the bulb (service call).

I actually found the solution, my manaul for the TV was missing a couple pages, very weird. I found the full manual online and there is a chart that shows what the blinking lights mean. It was my lamp, after I took it out it looked like it had exploded, so I ordered a new one from toshiba and replaced it. Very easy to do, costed about 120 for the lamp but no problems since.
Thanks for all of the responses.

If your set all of a sudden won't come on, e.g., the screen is blank, but the LED on
the under the screen next to the on/off switch keeps flashing, then there may be an
internal fault on the set that needs to be reset.
To force the reset, try this:

You say it's a DLP yet the model number shows as a standard projection, anyway what you seem to have is a Hyper board problem, many shops can repair this Fragile board but it's not for the weekend tv tech to try to do

You will need to trouble shoot the start up and shutdown circuits. Often this is a minor component failing causing the set to not power up or go into protective shutdown. Do you have the service manual for this TV?

You now have a defective lamp ballast board. It sometimes is the root cause of lamp failures in these sets. The problem here is that Toshiba does not sell the ballast board independently from the larger, more expensive light engine assy. Call Best Buy back and get a servicer out there. He may have to take the ballast board out of your TV and send it out for rebuilding.
