Samsung HLN 4365 wxixaa with Light engine failure????

I have a samsung HLN 4365 w that is in a repair shop and the tech is saying that a light engine needs replacement and this will cost $650.00 to replace.
The tv when first powered on, is fantastic with fantastic picture, then as it stays on, it will black out or pixalate and freeze up. Then when we turn it off, and then turn it back on, again we have a fantastic picture. So, I would think that a light engine would be a constant picture problem rather than off and on. I wonder if it could be a heating problem and a ballast problem ..? Any information that anyone could offer would be greatly appreciated.

When the tech said light engine what he ment was DMD board, the DMD board is the most important component on the light engine and most expensive, but still a lot cheaper then the entire light engine.

The DMD board can definetly, and often does cause intermitant errors. Your problem is absolutely not the Ballast, all the ballast is supply the power to turn on the lamp.

Your tech was right to go to the DMD board, the only other option that it could be is a digital board, you would have to see if it is doing this on all inputs.

I replaced my lamp and my lamp ballast in my dlp tv but i have a dark picture its samsung hl56a650

As long as you used the correct lamp and ballast, about the only thing left would be the light tunnel which is part of the light engine(optical block) which is very expensive to replace. Was it like this before the old lamp went out? the only time I've seen this at the shop, is when the wrong lamp was installed, but have read about a light tunnel failure as a possibility. This is kind of a long shot, but look at all of the electrolytic capacitors on the power supply module if you can get to it, and see if any of them are bulged or domed on top rather than flat. I have seen caps cause this with different brands, but never on a Samsung. It may be worth spending a few dollars to let a shop give you an estimate on it.

A loud humming noise, as soon as I turn on tv, but picture and sound quality is good, could be a fan but which one Thank's Guenter

It could be a fan but most of the time it is the color wheel in the light engine. Samsung has a reputation for bad color wheels. Can be tricky to change and some had a circuit modification for new color wheel designs. Have a repair shop check it out. Should not be too expensive.

Red cirle in the center of my screen durning dark scenes

This sounds like the light engine has gone bad or has dust/dirt in the light tunnel or DMD assembly. The light engine would have to be removed to check for dirt. If the engine is bad it can cost over $800 just for the engine not including shop charge. Unit would need to be taken to a repair shop to find out what is actually causing the problem.

We have a Samsung 27" Dynaflat HD that won't turn on.

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. The question will be, is the part still available? Before paying a TV repair person $75+ to diagnose the problem, ask yourself if you're willing to pay $150 minimum to fix this particular set. Also keep in mind that most TVs that old have a very limited number of replacement parts still available. Normally it will cost at least $75 to have the set looked at by a repair shop (diagnostics). If the part needed to complete the repair isn't available, you won't get that money back.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here.

Please let me know if I can be of further assistance.

Samsung big screen tv has white dots thousands of them

My Samsung was fixed for "free." Call Samsung service 800 number. When asked why you are calling tell them it is about the white dots problem. The tech said he would help me solve the issue and provide me with repair order from a local Electronics dealer. I was given a work order number by the tech and did receive a call from the local repair organization. My DLP is over 36 months old so I asked if this was a "no charge" fix. He assured me that it is. Low and behold I am 100% satisfied with Samsung and the standing behind the product. The fix is a chip replacement that Samsung is well aware of.
