Wow, I've been an installer and salesman in the consumer electronics industry since before the first plasma TV came out (Phillips 42" and Fujitsu 42" in 1996) and this is the first time I've ever seen that kind of an answer. "Take this to a repairman and he can add more plasma" what is the repairman a doctor. If it were that easy no one would ever have to upgrade or replace their screens. You can't add more plasma to a screen, if you don't believe me call Samsung and ask them for yourself like I did. I was actually so dumbfounded by your answer that I called a tech friend of mine at Samsung and asked him, his answer; "does this guy work for you?" I told him no and he said, "I was going to tell you to fire him because that's the dumbest thing I've ever heard anyone tell a customer".
What you need to do is take you plasma TV to an AUTHORIZED Samsung dealer/repair shop and inquire about the hazing/ghosting problem with them.

After about 5 years the Samsung LCD televisions backlight fails which prevents the TV from coming on and the powerlight just flickers the backlight can be changed but it is often alot easier and cheaper to buy a new Television

It would be a lot cheaper if you just replace the two caps that have gone bad. Just get a cheap solder pencil from the store and about an inch of solder and you are in business.
The Power Supply Board is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.
Thaks for using FIXYA, BIG IRISH.

Hello solidsnake55, my names Dave.
I Have worked on this model of TV many times! This model has a power supply that is a two in one! Meaning it is the mean power supply / inverter board! If you look at the top side of the power supply you will see that there are two wires that go to the back light of the TV one is light blue and the other is pink! I think! Anyway next to where they plug in to the power supply is the main inverter! it is square 2 1/2 inch's by 2 1/2 inch's. You will want to check all the solder joint to the inverter on the back side of the board! Theres a good chance that you have a bad solder joint and all you'll need to do is re-solder the bad joint to complete the repair! This is a common problem for this particular power supply!
