I used a DLP for my gaming tv for a long time(still have it as a back up for my projector).Mitsubishi or Samsung DLP I dont remember which.
If they had that much problems with the bulb they had a bad TV or they should try turning it off from time to time.Have fun replacing the bulbs in those.....they go out quite a bit.
Nice pic when it works though. Just about bought a 73" DLP Mitsubishi for 1100 off QVC this year....but remember my parents going through bulbs every few months. 99 smacks each time.
For free though, hard to beat that.
Oh yes, becase of course it was on 24/7......If they had that much problems with the bulb they had a bad TV or they should try turning it off from time to time.
