Help! DLP TV Shutting off and restarting all by itself

by meltonlv / March 5, 2009 5:58 AM PST

I hope you can help me. I own a 56" Samsung DLP TV Model Number HL56A650C1F. I fell asleep last night watching TV, and when I woke up the TV was shutting down and restarting all by itself over and over again. When it shuts down, it immediately tries to restart. The chime sounds, the power light comes on, the fans all start, the lamp comes on, but then after the picture comes on, within 5 seconds, it shuts itself off, and the process starts all over again. I can't stop it from doing it. I have to unplug the TV from power just to get it to stop. When I do plug it back in, it starts all over again, and I haven't even touched a button. Is this a power supply issue, or a ballast issue? I am mildly technically savvy, and would like to see if there is anything I can do to fix this, but I would like to see where to start. Thanks for any help you can give.

Reseat or service...

The only "mildly savvy" thing I might suggest is trying to reseat the lamp.

There's a great video tutorial available on the website located here: We just put those up last week (and no, guys, that's not me in the video).

If the reseat doesn't fix the problem, you might want to have a service tech come out and inspect or repair the unit.

Hope that helps!

I have done that several times - still no difference - How about something more involved? Is this a power issue?

Same problem, no help from Samsung

I bought a Samsung 56 inch DLP (model HLN567wx) in September 2003. I also purchased an extended warranty. Total cost for TV, warranty and tax was $5000. The TV was in storage for 6 months and in less than a year after that the color wheel had to be replaced. The TV worked fine for awhile and I really enjoyed it. Then around the time the extended warranty expired, it started to have the problems people have been mentioning - turning on and off, requiring power recycling, etc. Turning on but no picture, distorted picture, etc.

I started contacting Samsung in September 2009. They refused to be of any help since it was out of warranty. My research had led me to believe that there was a design or parts reliability problem since a tech had said that they received reports of problems with this TV on a daily basis from unhappy customers.

Samsung bounced be around between the customer relations group and the executive customer relations group. No one ever admitted a systemic problem with the TV or offered to help pay for the repair (contrary to what I have experienced with GE and other more reputable manufacturers who were willing to offer some assistance even if the appliance was out of warranty - I guess they actually care about customer relations).

After speaking with several techs I dumped the TV. Later I found out that the TV had been the subject of two recalls by Samsung - the problem was either the light engine or the DSP board. Of course, no one I spoke to at Samsung could bother to tell me this during the 3-4 months I was speaking with them.

I doubt if I will ever buy a Samsung product again.

We are having this same problem. Technician came out and said he THINKS it is the color wheel. He could not find ANYWHERE to buy the part....NOT EVEN Samsung. So does anyone know where to purchase a color wheel for this model? Or is there another possible cause?

I'd like to ask one thing.

Is this tech from Samsung or it's affiliates? Did you try 1800SAMSUNG to arrange for this service?

Yes. This tech was from an affiliate of Samsung. Yes Samsung says it is on back order and from some of the post I have read it has been on back order for at least 2 months. Samsung just has the part as 'No longer available'.

Be sure to call it in one more time.
