The power board is the one that the power lead connects to on the back of the panel there is two fuses on the board check them for continuity and replace if blown with ones of the same values
look at the tops of the capacitors for popping they should be flat topped not bulging up replace any that are bulging
finding a supplier for you without a geographic location for yourself is not possible
also you can get the power board repaired or replaced but the power surge during the failure could have damaged other components making it cheaper to replace the whole TV with a new one

Not a fix, but it got my tv on.
I removed the back and tried the power switch.
I located the relay that was clicking.
I have two blue relays in the middle of my power board.
I placed a hair dryer over the relay for a few minutes.
After four tries of the power switch and it stays on!!!!!
Heat keeps the relay from just clicking off.
I don't know why.
This will at least get the tv on though.

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. Follow this link to find an authorized repair center near you: http://www.samsung.com/us/support/repairlocation/serviceLocator.do?group=&type=&subtype=&model_nm=HP-R4262&dType=D&mType=UM&vType=R&prd_ia_cd=&acc_ia_fl=&disp_nm=HP-R4262

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.

When you remove the back of the set. You will fined a couple of caps on the power supply board that are bulged and they need to be replaced, or you can buy a new power supply at www.partstore.com. If you want to just purchase the caps, you can get them at www.mcmelectronics.com
SOURCE: Samsung Plasma tv pn43d450 tv wont turn on
If caps there not puffed or leaking voltages in and out of the power board must be checked next (right at turn on of the set) to see which come up and or instantly go off....this is the place to begin.
