DLP problem

Postby jeff6500 » Mon Aug 03, 2009 10:55 pm

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?

It's a light engine problem, most probably the DMD board is malfunctioning. Does the line affect the menu?

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

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?

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

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!!
