SOURCE: 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.

Hold down CTRL+ALT and hit the up arrow.
That should rotate your screen.

I have been repairing them through ebay due to the fact that they are not available to buy right now.
They've been out of stock for what seems like forever !!

SOURCE: my view sonic monitor does not work properly

sounds like the power supply inside of the monitor is going bad. did you replace the cable from tv to the wall?

replace the logic board, not the power supply board. you can find logic board on ebay as low as $29...
