Hello Sir, Hi, its the inverter board that powers the back light. this needs replacement. the board can be purchase online. try and find your model TV under manufacturer. If the board is available, have it installed by a technician.

    If it is a plasma TV it won't have a back light or an inverter, that is only on an LCD TV, it is more likely the power supply or the YSUS board. Plasma's are difficult. High voltages and currents and one board blows and takes others down with it. I am quite confident with electronic stuff but I have been beaten by a plasma and won't fix them now (Till I get some training!) BE warned!

As with other post where the detail of the make,model,series,ect. are not given this is a short generic description for Plasma screens. First of all as the plasmas tend to be relegated to the large screen environment. LCD's have only recently begun (era 2009-2011 ) to be manufactured in quantities with sizes larger than the 32"-42' sizes.
The Plasma and LCD apparatus are two very different pieces of equipment which accomplish the same task. The myths and misinformation abound for the operational phases of both . ie;
Dark picture with sound on a LCD would usually represent an inverter or back light failure.
Dark picture with sound on a Plasma ( which do not utilize the inverter / back light setup ) could represent a partial failure of the main power supply, an out of range video signal, thermal shut down of one or more power/regulators in section/group boards after the main power section/group board. Such as leaking/blown capacitors ( yes remnants of the capacitor plague are still with us) on the Video Group output section. In the afore mentioned scenario , the video would fail but the sound which is a separate circuit, group, and power rail would continue uninterrupted.
Plasmas like LCD are not mythical, rocket science, or magic. They just require a knowledge which is not familiar. A schematic or block diagram is a good start. A thorough knowledge signal circuitry and power circuitry help.
Where as I am awaiting approval under "fair use" to use a plasma schematic particular to a known brand, I cannot upload the item at present. I am currently seeking a good generic diagram/roadmap to illustrate the general layout in hopes making this a little easier to visualize.

I have a Samsung HP-T4264 plasma tv with a badly cracked screen. Can this screen be replaced with one from a Samsung HP-R4252C plasma TV.

No way, Jose!
Those bastards manufactures are always making sure you won't be able to use parts from one model to the other. Especially-display! LCD panels could be rigged, but no plazma's. Sorry!
Sell it for parts to some repair shop and get yourself LCD or LED panel. Plazma is gone!

Picture went out on p50hdm Vizio Plazma tv after loud POP

It's either the backlight lamp or backlight inverter is busted due to a power failure or fluctuation. Here's how to determine which is which:
  1. Grab a flashlight.
  2. Turn on the TV.
  3. Shine the flashlight onto the screen.
  4. If you cannot see any display even a faint one, the backlight inverter is dead, else the backlight lamps are busted.
  5. Replace which ever is the culprit.

When Playing Halo 3... The Screen Shrinks Down...

16:9 is the widescreen mode, the other size is 4:3 ratio which is what the game's native size, it is picture boxing by the plazma is showing the size as not to distort the image, to get the full screen picture, but make sure it's not the plazma's setting first - where it selects the size of the image, you may have the streched version on your normal play.

Samsung hpr4252x perfect picture in

You have a burn in problem from watching widescreen movies.If you have access to a signal generator or tv setup disc run a perfectly white screen on the plasma for about 30 min.This should help even out the pixels on the display.

Changing Screen Size on Samsung HP-R4272

you must not have the correct picture settings in the cable box, as although they are not HD they will still be widescreen, so check both tv and box for picture settings.
