I am having the same distortion shown by Ghendy, and am just checking to see what a solution may be?
The last time we had this repaired, the repairman said it would not be worth it to repair after that, but I am hoping there is a simple fix.
These white lines appeared recently and seem to be something specific. I also had warranty work done back when for the light engine and another repair that was done for about $100 by Samsung which might have been capacitors, but as much as I would hate to do it, dumping it may be the smartest thing to do.
I will research farther, but after seeing Ghendy's identical issue posted, I did not see a specific answer, only a statement of issue and frustration with the LED DLP experiment we all paid $3,000 to join several years ago before the real flat screen LED TV's were available.
This summer, I wore out the video switching IC relay (TEA645) on the input board (toggling dozens of times/day between computer HDMI and SAT HDMI) and bought a used replacement input board. It fixed the problem, but failed after only a week. The supplier sent me another and it lasted until this fall, when the set began losing the video completely when switching inputs. Unplugging the TV for a while would allow it to work again, but then at times it would get no picture when first turned on.
I tore the TV apart this week and discovered a second power supply board adjacent to the LED driver board in the shield directly above the LED fans. When I pulled the assembly and removed the shield, I saw the second power supply has the same design defect as the main power supply; there are two capacitors mounted right next to the heat sink, and both were blown. One is a 2200uf and the other is a 470uf. I replaced both capacitors, in their original positions and the TV will once again produce a picture, but the color is off and the ability to adjust the color is partially gone. I’m afraid that the blown capacitors damaged the DMD board, and there are none left in the world. Occasionally, when adjusting the brightness, the color mix will fluctuate wildly, but the B/W picture is fine. The reds are too intense and I’m missing the gold tones. I’m guessing the DMD board will fail any day now.
Sigh… I guess it’s time for a new TV. I loved this one. I just wish Samsung designed better power supply’s and used higher quality basic components in production. Are the new Samsung TVs more reliable?
5 years and ~5 months, seems about right after reading the last few pages. Sad that it had so many problems as I really liked the picture on this unit. Now what to replace it with... I have a giant stand that will look quite stupid with a flat panel TV.
the picture like everyone else here. People would be over watching a movie or Super Bowl etc. and
always ask why my tv looked better than theirs.
Thanks to every one that posted fixes or parts #'s to keep these running as long as they could.
As stated above, my power supply is not working. Is there anyone out there who I could send it to to fix it. ie replace the capacitors. I would be glad to pay you for your time and the capacitors you would need to order. I continue to enjoy the fine picture this tv has provided for 7 years and as a retired person, am a little short on the funds to buy a new one.
