Question about Samsung Televison & Video

1 Answer

Samsung HLT5687SX/XAA. Over a period of two days, 50 to 80 black spots appeared which look like dead bugs. Additionally, 15 to 20 white spots are readily identifyable. They have not increased in number and it has been 2 weeks now. Can I fix this myself? If not, what could I expect to be charged to fix the problem? I saw on online service in San Diego that charges $135 to diagnose the problem. Frankly, at that rate plus the charge to fix it i could go buy another t.v. for a little more.

SOURCE: Bottom half of the screen is black on Samsung HP-R5072 50 in. HDTV Plasma Television

It does sound a lot like a buffer board problem, Just which one is the question. Sometimes it is in fact a connection issue. But 1/2 of the screen missing sounds like maybe connection between the 2 buffer boards. It could possibly be the panel. If that is the case. ITs over for that set. But i would suggest first calling samsung and asking them to extend the warranty for 90 days or so. Sometimes they will do this for nice customer such as yourself. 1-800-SAMSUNG. Let me know how this turns out first then we can proceed further if needed. Good luck and keep me posted. Sincerely Jay

SOURCE: white spots on screen and growing every day

If these spots are small, they are likely the visual effect of a failing DLP chip. When some of the tiny mirrored surfaces on the chip stop moving, this is the result. This is not something you can fix yourself. A Samsung authorized service center will charge $400-$500 to replace it for you.

SOURCE: 42in Vizio black screen, no sound

I had the same issue happen to my vizio lcd just this weekend. Everyone is telling me is a bulb or backlight or something. It would explain the loud pop and no picture, but I'm not getting sound either so I'm not sure what exactly happened. Only after about 2 years too. I'm trying to find parts to just fix it myself.

Sound but no picture on samsung tv HLT5687SX/XAA


I unscrewed the panels on both sides of the tv to find out that the lamp was not turning on. What I did was I got my broom, tapped the lamp with it about 3 times when it was turned on, turned it off, tapped the lamp 3 more times, turned the tv on and it started working again.
