Toshiba 56hm66 New lamp worked last night, wont boot up again

My Toshiba 56hm66 TV blew the lamp after it was 2 1/2 years old. Under the extended service warranty, Best Buy sent me a new lamp and I installed it and watched TV for 3-hours last night. When I got up the next morning and turned on the TV, the blue light came on and you could hear a little click in the rear of the TV sounding like a switch. After about 7-8 seconds the lamp light would blink 15-times and then go off and you would hear the click in the rear of the TV again. After 7-8 seconds the above process would keep repeating until I would turn the TV off.

    Have the same problem. Lamp blew out, bought a replacement from dlplampexpress.com. Had the "cycling through" problem and returned the lamp, got the replacement yesterday and everything seemed fine. Woke up today to the same problem. How much does this problem estimate in fixing?

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.

New lamp worked for 2 weeks, last night would not turn in so removed lamp thinking it was burnt to send back under warranty. Lamp appeared fine so reinserted and tv surprisinly turned on. this morning...


Edwin, sounds like you might be having a problem with your Ballast. The Ballast is what fires up lamp. Typically if this is an older unit, when you replace the bulb, you will have to replace your ballast as well. It is harder to fire up a new bulb, then it is to fire up an old bulb. That's why you wouldn't notice the problem until you changed your bulb.

usually when the lamp is going out the picture gets dark if you are getting a rainbow tint most likely the light engine is going bad.

Sounds like the light engine if it's blowing the lamps. Are you sure all cooling fans are operating?
