DLP problem
I have a Samsung DLP ModHLR5067WX/XXA. Over 4 1/2 years my brightness has decreased and over the last year i've developed a transparent 2 1/2 line down the left side of my screen. Is this a light engine problem or something else?
Re: DLP problem
It's a light engine problem, most probably the DMD board is malfunctioning. Does the line affect the menu?

Re: DLP problem
No it's a transparent line on the left side of the screen that runs from the top to the bottom and only mildly effects the picture. What do I need to fix it, and is there a upgraded part to produce better viewing.NEhelp wrote:It's a light engine problem, most probably the DMD board is malfunctioning.

Re: DLP problem
Yes, the DMD board is part of the light engine. Replacing it should solve the issue you're experiencing.

Re: DLP problem
Regarding my Samsung DLP TV HLN5065W1X/XXA got real dark and I replaced the lamp (lamp had more than 8600 hrs). After I replaced the lamp, I have audio but not video. I am able to see the menu screens but no picture.
I tried the composite input with the result of audio but no picture. I tried the A/V input from a VCR with the result of audio but no picture. I tried the PC input and I got audio and picture. I see the lamp light, the fans all running, no abnormal noise, the video board has 3 green lights on. I went in the Service menu and all values match the service manual. I ran the Test Patterns and they all check out OK. Does anyone have any suggestions?

Re: DLP problem
I think your problem could be only in some ports of your analog board.

Re: DLP problem
Hello, can someone please help. I have a 50" Sony Flat Screen DLP TV....model#KDF-50WE655, it has a big Yellow spot that is almost over the entire screen, plus now I am getting hundreds of blue pixels to boot. I know it is not a lamp problem, but does anyone know how to fix this? Thanks!!
