Samsung HLS5065WX/XAA Red in dark areas of image

[Zaphod1962]

My television has started to display red in the dark areas of the image after warmup. Sorry if this has been covered before, I did not find anything when I searched the forum. This occurs on all inputs, and when I go to a standard def signal the bars on the side of te screen are red. Looking at buying a 55" Hitachi LCD if this will be expensive to fix.

I'm not really sure if I know what the cause is. The only things I can think of that cause this defect is a video board or light engine. If you have a photo of the picture you're getting (try to take one with the flash off), we can probably find someone who knows for sure what's wrong.

Ok I will try to get. Pic posted tonight. Thank you for the quick reply.

Ok of course last night the tv behaved, but I did find. An example of what is happening

oh man, that does look like a DMD/light engine failure. You'll have to replace the light engine in this instance because replace a DMD board costs almost as much as a light engine. If you get a tech out there, they can probably do it for you for $100, but you've also got to pay for the $300-400 light engine. DM usual has really good prices and their light engines come complete with a color wheel, so if that ever goes out, you'll be able to swap the old one if it's still good. Check to see if other techs reply to see if they agree with the assessment. Just by looking at the picture though, my first thought is DMD board. I could be wrong though ;)

Thanks for the help. I will check out the prices on the light engine. How difficult is. The replacement? I build PCs so I am comfortable working with electronics.

Ok checked DM. No light engine available for my TV. They recommended partstore.com. Light engine there is $882 DMD board is $196 would it. Be worth it to replace just. The DMD board? TV would not be worth spending over $800 to fix.

Sorry about the weird punctuation in my posts. Typing this on my blackberry storm and the keyboard does'nt like to cooperate.

Here is some info from what I have read on various posts and if similar to my problem it may be the digital board. Go into factory mode and check all test pattern images, DNIe etc, if all appear fine hook up a computer to the pc input. If the pc image is fine then it is not the DMD as apparently the pc input bypass the digital board (DNIe?) but the DMD is still being used. My color spectrum (red) looked off when trying to adjust the Index Delay and now looks fine once the digital board was replaced. I first replaced the color wheel but that did not fix the problem, my old color wheel may not have lasted anyway as it is hard to turn by hand so may have been worthwhile. Hope this helps.
