Hi, Youo have zeroed in on the problem area. It looks like a power supply problem. More often than not, there is a fuse inside. If you would venture to open the unit up, do a visual check on the fuse. If it is busted: 1. Clean - no burnt/scorching/black marks inside the glass tube, then you can simply replace and hopefully the unit will be operational; 2. Dark smudges - or small burnt metal pellets inside the glass tube, then it is possible that you have other defective components that caused the fuse to blow. Normal components that are known to go bad are the big capacitor and or the power transistor regulator. Most current designs uses a switch mode power supply where your mains AC voltage is converted to DC that powers a circuit that eventually produces a lower DC voltage say 12VDC for use of the monitor. Should you venture a DIY (do-it-yourself), pls remember safety precautions when working with powered electronics. Hope this be of some help/idea. Post back how things are or should you need further information. Good luck and kind regards.

You may have failing TFT (Thin Film Transistor, each pixel on the screen is driven by one transistor, so there are 100 of thousands on the LCD panel
) or bad connection or failing T-CON board.
See pictures here:
It will usually get worst with more lines as time goes by. New panel will be needed.

Click the Menu button and use the '+' & '-' signs to select restore factory settings. Check if you get the same line in the BIOS screen, if so then you would need a replacement.

Powers up, shows test menu then black screen

This sounds like a video problem with the COMPUTER.....try the monitor on another computer. Usually, if you can see the monitor test pattern the monitor is ok.

Horizontal lines are appearing and moving acrosss the screen of my View Sonic E50C Monitor...

What is wrong with your monitor is that the Horizontal section is going faulty, the lines you are seeing are the Horizontal Retrace lines, usually invisable in a working unit. It is often a faulty capacitor(s) OR a Diode breaking down.. in the area of the Flyback Transformer. Probably time for a new one unless ya can fix it yaself.
