Samsung forum: DLP Twon't turn on, blinking green lamp light then shuts dow

Tried reseating the lamp as you sugguested but that didn't work. I called a service tech who said it is almost surely my lamp and he would come out and replace it for $300. Pretty steep so I ordered a new Osram Lamp myself for $90 and installed it. unfortunately that didn't change anything.unit does the same thing. My unit is a PT50DL14X.I did notice that when the unit shuts down you can hear the color wheel just befoer it fully stops rotating. i.e no sound as it starts up and rotates at full speed but a low squeaking sound just before it stops rotating. Based on this I might suspect it to be the color wheen however based on some other posts the start-up sequence does a check on the color wheel before it fires up the lamp. Since my lamp comes on then I would not suspect it to be the color wheel. However the start-up sequence posted only goes up to when the lamp fires up. What is the next few steps in the startup sequence that gets the picture to actually project onto the screen. There must be more start-up steps because my TV has the color wheel running and the lamp full on but no picture and a dark screen.
Thanks for any assistance anyone can offer.

Fred, curious too if you had it fixed. Lamp works, ballast works, even replaced the power supply board, but it just doesnt' seem like it wants to project the image. There is no sound, so it seems like it's just missing one step. Very frustrating.

Did you call it in and get it inspected?

Here the service calls are over 100 (120?) so yours is a little lower.

As you suspected this isn't a TV repair discussion forum but folk do share if it's something well known and common.

I take it you tried that first idea and it's not some old bulb.

I didn't think that was user serviceable? I could be wrong.

Did the tech that did that work tell you what else could be wrong?

1. Or off with my head.

2. Use the web to see if there is some TV repair forum that notes it.

3. Get a Samsung Tech to give a quote.

4. Follow the old shop rule when you can't figure out what part next. (what rule?)
"Replace the cheapest part first."

If you are testing it before putting the back on the set, be sure to tape down the blue sensor switch located behind where the lamp cover door is on the back panel...the TV won't start up if the switch is in the middle or up position.
The ribbon wire coming out of the color wheel slides down into position easily (no connections), but make sure that the bare wire side is facing the contacts. It took me a while to figure that out.
Other than that, this was much easier than I thought.

im gonna take apart and have a look at that.. ill keep yall posted

ok so i accidently bought a new lamp from ebay £40.00 didnt think id win it at that price . Put it in and it worked! so my other "NEW" Samsung Lamp must be a dud but looks perfect no burnt element, threads have no wear!, hmm,

Did u ever find out the problem? Mines is doing the same thing.

Hey does anyone know where to get hold of a replacement power board?
