Most times with this happens you can repair it by replacing the buffer bds. Sometime the ysus bd is bad and unfortunately the panel can cause this problem. I would say 60% of the time the buffers will correct the problem. I usually replace both at the same time.

I have a 46 inch Samsung plasma HP R4252 picture went black


Probably the power supply that drives the video has gone bad. Samsung recommends the TV go to a service center. If you have some skill and are willing to try, open up the back of the TV, remove the shielding and look at the boards to identify any obvious damage. Leaking or bulging capacitors, soot, scorch marks are the obvious. (Other parts can have bad solder or tiny cracks that are hard to spot.)

http://www.shopjimmy.com/catalogsearch/result/index/q/HP-R4252 has reclaimed parts for this TV. These are parts from TVs that were damaged in shipping and were only run during quality control tests. They list several power supplies for the model so check what part number is actually installed (there is usually a label on the board).

I hope this helps.

Short circuit on the "Y" sustain board


The problem is heat!!! If the tv has fans they should be checked for normal operation,although on the early samsung models there were none, and the problem is that the panel drive buffers are getting to hot due to inadequate cooling. This is most apperent when tv is mounted to close to the wall, also external fan blowing on the rear left side will dissapate the heat. It is a problem on early Samsung and Electrograph 42 " plasma models. Hope this helps.

Samsung PS-42S5H


Since you smell it above one side of the panel I will guess the right side (from the front). This is where the Y Sustain board is located, it has large heatsinks over the drive ic's to dissapate heat. If the ic's are bad this is more than likely the smell. This board controls the scan of the picture and drives the plasma panel. I would definatly have a technician look at the unit, these are normaly econimical to repair.
