SOURCE: No Picture, sound is all static
CHECK YOUR VIDEO INPUTS. THE HD SIGNAL IS TAKING OVER ALOT OF THE ANALOG SIGNAL.MAYBE A STRONGER ANTENNA OR ADJUSMENTS MIGHT WORK AS WELL.

SOURCE: RCA tv only in black and white?
The route through the circuits in the TV from the various sources all lead to the final video amplifiers for red green and blue. Somewhere along the route is a circuit called a colour switch. This allows colour if the signal is strong enough, otherwise it only allows black and white. This fault suggests a weak video chip which is the one just before the switch circuit. the fault could also be a faulty coupling capacitor to or from this chip, or a low power supply voltage. Check for dry soldered joints around this circiut. Please note if resoldering on new televisions that they may have non leaded solder which requires about 50 degrees centigrade hotter iron.

If the screen split is exactly 50/50 top/bottom You are not getting SU or Scan Upper drive.
These are lovely set to work on.
Most likely is SU board itself - Not repairable just to be replaced.
Sorry I work in the UK so I can only guide that the UK part is around £30
SU may have been damaged by failure if the PDP (Plasma Display Panel) but is 9 years only had 2 screens damage the SU board.
There are several setups to do after fitting a PDP. If you don't have the service data - Do not risk it, Reduced life of the Panel and a safety risk.

Most likely your problem is on the DMD Assy Board P/N BP96-00249A . More presicely there is a few bad electronic components on that board that are bad. That board can be repaired by replacing the bad components (and the other few compoonents that are probly going bad and will soon cause your tv to lockup and lose remote and button functions when it fails so you will need to unplug it to get it on again).
Or the DMD board can be replaced .But it is not a cheap board.
For removal and Installation of the DMD board I would reccomend a tv service person because it is in the heart of the television and there are some adjustements to be made when the new board is installed.
To get the new board you could probably find it by just gooogling the part number.
Component level repair would require some experience in desoldering and soldering SMT,SMD , and or surface mount components.The actual components are about $15.00 total so just repairing your board should cost about $125.00 by a qualified servicer (if you were to remove and install it yourself). This DMD board is used in many models and can a few common problems.
HLM437W HLM4365W HLM5065W HLM507W HLM617W HLN437W HLN4365W HLN467W HLN507W HLN50665W HLN567W HLN617W ( L2 and L5 chassis )
-Intermittant picture freezing with a negative looking B/W frozen picture.
-Intermittant loss of pic with/without shutdown,abnormal color wheel noise if attempted to start after shutdown.
-lockup of tv control functions . Remote and front keypad do nothing , TV must be unplugged to reset .
-horizantal tearing, distortion , flippnig , solarization , red picture, leading to blank screen and lockup.(tv menu would be affected by all picture defects).
Hope this helps someone..

I had the same thing just happen and I used the following instructions from the Vizio Website for "humming sound" on tv and it worked. My sound is now working!!!!
1- Power off TV
2- Unplug TV from outlet
3- Press and hold in the power button on the TV for 30 seconds (while it is unplugged from the wall)
4- Release the power button
5- Plug in the TV into a different outlet
6- Power the TV back on.
Reset the TV settings.
