Question about Samsung HLR5667W 56" Rear Projection HDTV
My Samsung set is about 4-5 years old, and if memory serves I have replaced the lamp twice now. Sunday morning (during Draft Day 2) I heard a quiet pop, followed by darkness, a couple power cycles, then all three LED's flashing in unison.
I busted out my trusty backup lamp, slid it in, and nothing. No different result. The TV would again give the starting chime, slowly, three times, then go to three flashing LED's. No sound of the color wheel spinning up, no fans in motion (except for maybe the tiny one that is encased behind the input panel). So I assumed my backup tube must have been bad as well, and ordered a new one. $184 later and it arrived today. I slid this one in, and again, the same result. Plug in the power and I get three starting chimes, followed by the three flashing LED's. I have her torn pretty well down now, and nothing appears or sounds fully out of place, except that the lamp never fires up at all.
Strangely, it's the exact same behavior as if there is no lamp installed at all, if you just slide out the lamp, replace the cover, and try and power it up. So my thought is that it may be the ballast, or that maybe I have defied the odds and received a bad tube. Is there any way to conclusively know that a halogen tube is bad? Or that the ballast needs replaced?
Thanks, all, in advance.
Unfortunately, I can not see what you have been told thus far, so I'll need to get a history from you please. The 3 flashing LEDs indicate a lamp problem (as you know). I think that you have thus far replaced the lamp, ballast and power supply modules correct? I hate to be the bearer of possibly bad news, but there are a number of interlocks built into the system that can cause this type of message to appear. With the set re-assembled, check ALL of the access doors and panels. If ANY of them is not 100% seated correctly, the lamp won't fire and the 3 LEDs will display. Also, you should have gotten the lamp hours reset procedure as well. Try resetting the lamp hours again (if you have tried already) and post whether or not there is a change in behavior. The incorrect setting of this parameter will also prevent the lamp from firing.
I look forward to more details around the history of this problem and hopefully we can solve it shortly.

Ok, when handling the halogen, you will have to pay close attention to not touch any part of the halogen bulb with your bare hands. this will cause the bulb to short when inserted due to oil transfer from your finger or hands. use a latex glove when handling a halogen tube.
As for the ballast. if you have used the correct procedure when handling the bulb and you have not touched the replacement bulb, this will confirm a faulty ballast.
