Help! DLP Trouble-Shooting
I've got a 61" Samsung DLP in the living room that started giving me problems yesterday. I've had the TV for about 18 months and since I travel a lot, use it fairly infrequently.
Yesterday, I turned the TV on and it started up as usual. After about 30 seconds, the picture went to black, but the audio remained for about 3-5 seconds before it too cut out and the TV automatically shut down. All three LED lights on the TV began blinking (Standby/Temp, Timer and Lamp). I un-plugged the set and powered it back up twice with the same results.
I know that the lamps are consumable parts in DLP's, so I thought that would be the best place to start looking. I pulled the lamp out and visually, it looks just fine. No discoloration, filament is intact, doesn't rattle, etc...
When I replaced the lamp, the TV now won't power up at all, and I think it's now just the Standby and Lamp LED's that blink. I pulled my 42" LCD off my wall of my bedroom and am now using that in my living room, but I'm hoping you guys can help me diagnose the problem.
If it were the lamp, would it even give me the picture as it initially did? Would there be any visiual indication that the bulb is bad?
Could it be the ballast? I'm told that the ballast is the power supply for the lamp, and that they go bad sometimes too. I don't think it's the color wheel, because there was no noises at all associated with the failure.
Can anyone provide any insight?
Thanks in advance.
