I recently purchased a Samsung PS50P91FD 50 in plasma and when turned on after approx 15 minutes it makes a crackling noise from all around the front of the screen. Sounds like the front plastic cover? It goes away after approx 2 -3 hours of being on.
I think it may be heat related? Is there a way to fox this? A Samsung tv technician came around and said it was the first time he encountered it and that there was nothing he could do. He opened the unit and tightened all screws but the problem still persists. This is the second tv as the retailer i bought it from exchanged the first one as it had the same problem.

My tv turns on and off by itself the minute I plug in the cable. ....Samsung E6030 led tv hv blinkin red light issue ... capacitors are looking good ...
that it is likely a power supply problem. It starts with a loud popping
or crackling noise and then the set goes dead, except for a flashing red
light on the front. best thing to do here is to unplug it from the power for a good min or 5 make sure the TV is not hot and try plugging it back in , also Plasma TVs and Samsung have had this problem for a long time this is the info i found for you.
The Panasonic Viera 50-inch plasma TV has received rave reviews from the
media and consumers alike. Panasonic encountered problems with its
plasma TVs last year, both due to degradation of the picture quality
over time, which was much publicized due to a class action lawsuit filed
over that defect, and for a power supply issue that was far less
publicized, but for which there are many negative reviews online. So far
this year, though, the reviews have been much more positive. I would
like to share, however, that my experience has been less than positive
in hopes of helping others who have had the same problem and in
providing another viewpoint for those considering purchasing this TV.
Hi, this is quite a common problem for plasma screens and LCD screens. The fluroscent backlight is more than likely faulty and would need replacing. The best thing to do is to take it to a service centre because there are no user servicable parts inside the plasma.
Hi there mate i was just reading your article and wandered if u managed to get it repaired! if not i was wandering if you were interested in selling it as i have the same tv with hardware issues! just a stab in the dark! my addy is firstname.lastname@example.org
You should call for warranty service. If the set is very new try to get it exchanged.
There are some very heavy duty power supplies and many high power matrix drivers used in Plasma sets.
The description sounds like the noises are very loud. It is normal with any of these TV sets, if you put your ear right up to the back of the set at the vent holes you will hear some noises. These would be some acoustic harmonics from the power supplies and related circuits.
I am wondering if it is possible that there is something that is becoming less stable. If the set is working very well without any failure, so-far this is a very good sign. Before it gets to be a problem, I would have this checked.
On many models of these sets, they use fans for cooling specific areas. A bad fan can cause noise.
