DLP lamps

Could be a defective lamp or defective powersupply in "projector". Lucky to have it go while under warranty. I've "lost" 2 or 3 lamps well before their time, not under warranty. (most are 90 day warranty) Lamp has higher voltage/current "starting" mode, than operating mode. Lamp degrades each time it's powered up. If they would "standardize" lamps they could be half the $$$ they are now

I have the 52 inch model and had the same probem. I bought my television through Best Buy, and ended up getting replacement bulbs in 7-10 days from both Best Buy and Toshiba. Then, a few days later, we received a letter from Toshiba stating that there had been many problems with the bulbs in these televisions, that they had developed a better, more reliable bulb, and would be sending these out very soon. We have not received it yet, but expect yet another replacement bulb any time. In short, we have a new bulb, a replacement for that one, and yet another replacement on the way. That should cover us for at least a good while.

I have read quite a bit online about this issue, and the consensus seems to be that the bulbs that come with the televisions are generally duds, but that the replacement bulbs appear to be working fine. It is annoying, but I am hopeful that the problem is now fixed, and that the newer bulbs will last a good long time before being replaced.

I recommend that you contact Toshiba directly for more information and a replacement bulb. Good luck.

I understand that lamp life is severely affected by use. Don't leave one on for more than 8 hours at a time. Wait one hour before turning one on after turning off. And if your model has a power saving feature, use it. I have had a DLP projector now for four years, no problem.
