Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should troubles shoot. Contact any service technician. The circuit will differ with models and versions.
Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy.

SOURCE: Panasonic TH-42PX60U PLasma - 1/2 screen blacked out

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.

SOURCE: thin horizontal black line appeared lower half of

Fixed non moving lines usually means you have a problem in the panel display or t-con. If it is in warranty get it to a factory authorized service center. If not you can try to change the t-con and see if this fixes the problem, if not then it will be the panel it's self and will be cost prohibitive to repair.

My monitor goes half red pin striped and black w/ some visibility


It sounds like you may have connections problem (loose or dirty contacts) between the LCD panel and the logic board, look for that first, worst case will the LCD controller (T-CON) board, which is part of the LCD screen panel assembly.

Right half of screen is Black with a White vertical stripe


Yeah, I have this exact same problem, except my mom slammed my laptop shut in frustration around half an hour ago, so that's why it's like this. The right half of my screen is black with two colorful stripes (mostly white), but the left half is visible. I've researched a bit and found out that this is because the LCD in your monitor has burnt out, and since you don't have a monitor to attach, the only thing you can do is to go to where you bought the laptop and either get it fixed for free or return it for a brand new one (if your warranty still stands). If not, you might as well get a new laptop. I think my warranty has expired, so I'll get a new laptop, hopefully.

Hope this helps!

this is a chip on film problem it can't be fixed if your set is still under warrenty you can have it replaced. The repair site will scrap the unit because the chip is actually embedded in the screen.
