Hi...what you are seeing is the DMD board (digital Mirror display board) going bad. And if you leave it turned on like that it will damage the DMD mirror and freeze that picture into the mirror. It will look as if someone etched it into the mirror. DMD boards can be repaired and some cannot be repaired. The DMD board can be replaced. The DMD mirror can also be replaced too.

Open the tv in the back. I had the same problem and was finally able to resolve it. If you remove the cover in the back of where it says lamp you will see a lil lever near one of the metal brackets. Make sure that small lever is pushed all the way in, it should already have a small strip of masking tape on it. Push it all the way in and then try it.

This helped with mine and I had a simular problem. Good Luck

Its possible that the speed of the color wheel motor is starting to drift from the normal range. Its also possible that the DMD board or digital P.C.B. are the culprit.

Contact an authorized Samsung service center, ask them to try to reset the wheel speed using the index delay parameter in the service menu.

They should be able to eliminate the problem or at least identify it as a bad color wheel or otherwise.

That set has 2 DVI connectors in the back. Either one will work if you have a cable that matches.
The manual is available online too

try to put away any electric device which is near your tv set

if the picture is still visible but lacking color, it is not the lamp. check the color wheel and make sure it is working. replacing the color wheel is a pretty easy task and can be performed by yourself without many problems. as a sidenote, older samsung dlp tvs seem to experience this problem quite often, although they usually sound like someone strangling a cat before the bearings go out..

partstore.com should carry your replacement for 100 USD or so, the part number is BP96-00250A.

before replacing it, make sure your old one isn't just stuck or not spinning at full rpm, if this is the case, you can usually remove it and clean the motor using electronic or contact cleaner that is safe for plastics.

to check everything out, you will need to remove the back panel of your tv, then power it up (keep kids, small animals, hands and such away from the back while powered up), take a look in front of the projection lamp and see if the wheel is turning. if not, a very good writeup is available here, this is the writeup i send my own customers to if they feel like attempting the repair themselves.

replacing the color wheel is actually not very hard at all, if you have ever worked on your own desktop pc (installed a new drive or upgraded it yourself) then you should be able to do this with limited difficulty.

hope this helps,

Did you reset the hours on the lamp with the menu options on your set? Sometimes, if you do not do that it can mess with the tv performance thinking that its over hours. It needs to be reset to 0 again...

That could either be the cooling fan bad or the light engine assembly as they both can exhibit the sympton your describing. Can you haer this sound as soon as the power is pushed or does it take a moment. If its instantly chances are its the fan.

Samsung HLN4365W... | Answered on May 24, 2008

Not all the time but yes I have seen it happen about 60% of the time with the DMD board going bad. But it is possible that the DMD board is not the only problem your TV is having. The digital board (another board in your tv) can cause both these problems at the same time too. It is something that needs to be troubleshooted. But this info will narrow it down for you.

Your lamp has went bad and you need to replace it. If you look on the left side of your tv there is a sticker that has a lamp part number on it. You can order that from part store.com and you will be back up and running.

sound if u might have what is called a crt burn

You might want to unlpug the powercord for the night, then plug it back in the next morning. Some times that can help reset things. If that still doesnt do the trick, you might have a faulty power cord. If it does this with every source you hook up to your TV then that would be a sign that its something in the set vs. your external source.

remove the back cover u will see the fans one for the ballast and the other for the lamp

Sounds like a door switch is not making proper contact--or has been damaged. Check the lamp door switch and see if it is properly seated and the pin on the door is hitting the leaf of the switch.

You need a color wheel--common on these sets. Get a real phillips bulb and you should be set for awhile. The cheap generic bulbs are fine to get you through a few MONTHS....but NOT much longer. . An E22H-120/132 watt lamp is correct--and if you can replace just the bulb-(NOT hard at all to do) it will save you a LOT of money.
