My Samsung DLP hlp4663wx/xaa TV has scrambled picture

The picture on my Samsung hlp4663wx/xaa DLP TV just went scrambled while we were watching it. It has moments of close-to-clarity, but normally is now just completely scrambled. The sound works. I have unplugged it for 30 minutes to no avail. I removed the cover to the lamp area, just to look. When I put the cover back and turned it on, the picture was normal for about 15 seconds, then went back to scrambled. Any help would be greatly appreciated!

    To check the fuses on the board (which board?), do I need to remove more than the cover to the lamp?



    Thanks,

    I removed the full back panel. There were a few boards in there. The board with all the inputs on it was hard to see because it was inside of a metal casing. I shone a flashlight through the holes and there didn't appear to be any fuses in there. One of the other boards had a fuse on it, and it tested fine (with an ohm meter).



    The TV is about 4.5 years old. What's the DMD board and where can I get one? How much should I expect to pay? Once I get it, will it be straight forward where it goes inside? I'm highly technical, just not necessarily with TV's.



    Thank you!

    I'm having trouble with this site...it seems that some of the solutions are there sometimes and not others. Any help would be appreciated. I don't know much about TV's, but I'm pretty technical, so I can probably handle a repair as longs as I don't need special tools.

    Thanks!

    CRTN,

    Not that this is related, but what's really weird about this FixYa site is 1) I don't get emails when a comment is posted (I do have the option checked in my profile), and, 2) when I'm signed in, I only see the comment by rejakwilson and not yours or the other one. So, I have to sign out, read the comment, then sign back in to repsond. Odd.



    Anyway, I'm going to buy a color wheel. Can you point me to where on the inside it goes, so I'm not taking apart the whole thing unnecessarily? Here's a picture of the inside.



    Thanks,

    Bob

    Still waiting on the part...grr!

    The color wheel just arrived and I installed it. After about 30 minutes of running normally, the problem returned.

    What next?

I had a problem with a flashing problem. A technician came to our home and started off by replacing the DMD board. That didn't help. He took it back to the shop and they ended up putting in a new Color Wheel and a new LDVS cable. It was then adjusted, cleaned, and tested. All is well now.

    You need to remove the cover to check all the fuses on the board . If your fuses tend to be ok then you need to replace the DMD board . How old is your tv ?

You may have to blow out the dust (if any) inside the set (a common reason). Or if the picture scrambles up any before going out you may need to replace the color wheel. And it is possible the fan could be breaking down or slowing down and causing overheating which will make the thermal switch to cut the set off.

Samsung HLP4663WX/XAA picture went out, started making strange noise, all lights on power button came on.


Sounds likea bad color wheel to me, or possibly a lamp has blown. If the noise is a humming sound--it is the CW--if you hear a "sound like a sizzle, for a few seconds and then normal, and this repeats a few times--the lamp has blown.

I don't have the manual handy at the moment. but if you look in the owner's manual you should see that this is the code for either a lamp or fan problem. I will look it up myself later, but check the manual. This could be as simple as replacing the lamp.

Blinking lights


Sounds like the color wheel. Check samsungparts.com for a replacement. Check the video on youtube of a guy fixing his color wheel to see if its something you want to tackle. I changed mine... a drag, but not too awful. Ran about $100.
