We have a Samsung plasma and noticed the glass sliding down as well. We popped the plastic frame off and put the glass back in place and then put new double sided sticky tape down across where the old tape was. We popped the frame back on and the glass hasnt moved at all. I did call Samsung and our warranty ended last month, so I am waiting for them to call me on setting up a tech to come out. However I do feel that we shouldnt have to pay for this since they did not secure the glass besides some sticky tape and a plastic frame! I will post what Samsung says after I receive the call from the technician on how to fix this problem. But this has fixed the problem for now.

I now have the same issue. What did you do?

Best option is to switch from the HDMI to component input. This is an HDMI compatibility problem between your TV and cable box. You will still be HD but you won't have the blinking out issue. I hope this was of some assistance, best wishes.

Try several inputs. See if you have the sam result. If you are watching with an antenna make sure all is connected and setup is set up.

Try set up for the TV with its' remote.If it works on the blank screen that means an input problem.

This particular model has a 60Hz refresh rate. At this point there are no broadcasts or video sources outside of special labs that can generate enough data to produce a refresh rate of 120Hz. Expect this to become available in a year or so. Please realize that the human eye can not see changes faster than about 30 frames per second. The current standard refresh rate of 60Hz is twice that. The only change you could see (unlikely) would be a slightly smoother flow for fast moving scenes. Typical movement on the screen will not likely see a difference.

If possible turn one off and tune the other. Then turn the other off and tune it. Then turn on the other. That is your only option at this point.

I just looked up the manual online and it clearly shows that the screw size is M4 x L12 metric screws

check the display strip. un plug it and fix it

the capacitors seem to have gone bad if they have like a black dot on them it is a sign they have actually blown they can be replaced by placing new ones on but it would be better if the board was replaced (unless you wish to replace those capacitors please please do be careful in doing so they hold enough charge to give you a bad zap even kill if one isnt careful)

Plasma TVs are difficult to repair. I have not repaired the particular model you ask about. I would certainly pull the power supply board and inspect it for a bad solder ground. Many times this will repair the TV. Be sure to also take a leaf blower to the open back of the TV as well. Dust will act as an insulator, and create extra heat that will break your solder grounds. If worst is to meet worse, you may have a bad Y suspension board. The Y suspension board will take some effort to remove, and if this board is bad, send it in for repair. But let me remind you, the first note of this info is the best effort to fix at any level, and is usually the problem. Also, there may be one bad capacitor on the power supply as well, replace with same value. If you cannot repair this TV yourself, take this info to a TV Tech.Thanks for asking me!
