It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

SOURCE: ESA 42" plasma tv not turning on
I have a 42 inch plasma and I was watching tv last night on it and suddenly it turned off on it's own. I tried turning it off and on and nothing happened. Then I tried to unplug it and replug it and nothing. My remote does not work either. Anyone know what exactly happened? Did my screen blow or what? I hardly ever use the tv and I only had it on from 8:30 p.m. - 10:20 p.m. and it turned off. All the other tv's in my house worked fine - I checked them. Also, my dvd player and cable box is on the same power cord and both of them work. Any solutions or help would be most appreciated!!! Does it just need to cool down or did I burn something out? Help!!!

SOURCE: viewsonic n3251w - no power
A lot of TVs are having their power boards go bad due to a poor brand of capacitor (CapXon usually).
If small problems are noticed with the tv, the solution is to replace the capacitors. However, once the TV gets to the point where there is no power at all any more (not even a stand-by light) then the power supply has to be replaced.
Visit Viewsonic's website or call your local Viewsonic repair shop to get a price on this board. They are usually under $100.

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.
