Question about Samsung HLN5065W 50" Rear Projection HDTV-Ready Television

1 Answer

Negative image and then black and won't turn off!

I have a Samsung 50" with a model number HLN507WX/XAA and serial number 31EW900529N.
About a month ago it started giving me a negative image on the screen that would freeze and I would have to turn it off and wait for awhile to turn it back on. It would then work for a few days and do the same thing. Then it just didn't give a picture anymore. When you turn it on you can hear whining from the back and it sounds like it want to turn on, then you hear it cycle through again, all 3 lights on the front flash and eventually you hear a pop sound and then nothing. I have to unplug it to turn it off after that. I was going to replace the lamp but in the process of searching for a replacement cost came across this site and realized others had similar problems but with different samsung T.V.'s and slightly different problems.
Please any help would be appreciated.
I love the T.V., the picture is great when it works and I want to fix it, but don't want to fix the wrong thing if I don't have to.

    I have the exact same issue. I have contacted PTS Electronics and need to send the board to them for examination to see if it can be repaired. Is there an easy way to get to the board?

The negative image on the screen is the DMD board (Digital Mirror Board). The cycle sound is the color wheel trying to spin but if the DMD board is going bad, it will effect the color wheel and not spin. There for your image will freeze.

    Sometimes the DMD board can be repair. But do understand not all can be fixed. I have seen them on Ebay for sale at the best prices.

Picture is black and white and fleckers. changed

In most cases this is due to the fact that the color wheel has shattered into pieces and will need to be replaced. Replacing the color wheel is not too easy, but if you are technically handy it isn't that tough to replace either. The part number for the color wheel is BP96-00250A and will run between 80-130 dollars for the part.

Tv freezes white and black negative image

Yes the digital board is the culprit. I need the complete model number so I can get you the correct part number. On the right hand side of the TV is a sticker with the model/serial and sometimes a version number. Get me all those and I will look up the part number.
