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.

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 !!

Fading colour

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

I have view sonic VA1703wb lcd & the problem is screen is blinking all capacitores r ok but still this problem so any one have a solution of this problem ?

The only thing you can try is turn down the brightness, this will address some monitor issues, if this fails the inverter transformers should be suspect.

Va1703 wb blinking problem


That is a sure indication of a failure in the power supply board. The problem is that Viewsonic used two different power supply boards in the va1703wb model. If you want to do the repair yourself you should be able to. If you can open the unit and send a picture of the power supply board to us at we would be glad to show you what parts need to be replaced to rebuild the board and get it back up and running.

The view sonic VA1701WB display is totally white on the screen during up the computer and i check the CPU is booting up but at the same time monitor screen is totally white please reply the reason.

It can be due to:
Dead T-CON board on the LCD panel assembly due to blown fuse or just dead board.
Dead power supply on the logic board that supplys the power to the T-CON board.

In my View sonic CRT monitor E71f 17",there is a curve appearing on the upper side of the screen and there is some space between the display and the screen, please help. thanks

It's time to responsibly recycle your old CRT monitor, and spend about $100 to buy a new 17" or 19" LCD screen, rather than spending any money at a qualified TV/video technician, trying to trouble-shoot the problem.

Monitor won't display resolution properly after Windows Update

I was having the same problem. Believe it or not I fixed it by unplugging the monitor, and when I restarted my PC I again had the 1440 × 900 option.
