DLP Twon't turn on, blinking green lamp light then shuts do
I'm sorry to hear that you're having this issue.
It may be that your unit requires service. However, before that, you might try re-seating the lamp. To do this, with the TV unplugged, open the lamp door, unscrew or unhook the lamp, slide it out, and then firmly push the lamp housing back in. In some cases, this fixes the symptom.
If that doesn't work, I'd recommend calling 800-SAMSUNG to have your unit inspected and serviced.
Replaced lamp still no picture or sound
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.
DLP won't turn on, blinking green lamp light then shuts down
Fred did you get this problem fixed? My 50" DLP just started doing the same.
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 get your tv fixed? I am dealing with the same problem.
Read the notes above.
Did you call it in and get it inspected?
Called Samsung and they gave me the number of a local repair shop. They cant tell mejust by my description of the problem what the solution could be or even if they have had any other customers with the same problem. of course they want me to lug the thing down for a $65 service fee or $100 in home.
Sounds about right.
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.
Yes, changed bulb with a Samsung brand and ballast, no change to TV operation
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?
No he didnt. So now we are stuck. Has anyone else foudn a solution or an idea what could be the problem?
Ideas. Off the top of my head.
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."
Whoops! How many discussions did you post in?
a couple of very easy things to be sure to check
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.
thanks man,,,tv sorted,,,what a stupid little thing...:)
@Newfieace (or anyone else having this problem),
Were you able to fix this issue? I am having the exact same problem, the lamp was replaced a few months ago and it does turn on, I also replaced the wheel 3 months ago because the old one was shot, the TV worked for a couple of months and suddenly stopped working. Exact same symptoms as described by Newfieace, so I am very curious on what I can try next.
Any help is greatly appreciated.
ima try it
im gonna take apart and have a look at that.. ill keep yall posted
I have the same issue
i have the same issue SP50L6HD, I replaced the colour wheel as it was whining, the Ballast clicks on power up showing its fine, the lamp lights up, i get a picture for about 3sec then goes to standby and it cycles the boot process. GGGRRR very frustrating!
Some how it worked! Fully operational
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,
its not a phillips or samsung make of lamp, i was in a rush to get it in i didn't take note :s silly i know but i guess i was more concerned what would happen to the tv if it didn't work! its made in china so 1 up for china!
Did u ever find out the problem? Mines is doing the same thing.
replaced lamp and color wheel recently
This problem started a few days ago. I had both replaced in the last year.
I tried unplugging the unit for 5 minutes, then plugging it back in. It seems to work now.
Hey does anyone know where to get hold of a replacement power board?
Ebay, samsungparts.com amazon.com
Replaced lamp and now TV shuts off after powering up
Did you ever get this resolved? My TV is now doing the same thing. It is about 10 years old. I just replaced the lamp for the 2nd time, and now it will power up but then shut down.. After a few tries it will usually stay on, but obviously something is going.
