Question about Computers & Internet

1 Answer

Turned computer on one day last week and the Dell E171 flat panel monitor showed nothing but vertical lines. The mouse showed as a strange assortment of colors in a small square and the screen adjustment menu comes up perfectly. None of the monitor adjustments change the vertical line problem. Any suggestions? Much obliged, Carl Perkins

Try another monitor, then change the graphics settings to lowest possible, then reboot the PC, and see if your screen works again, if it does, check the documentation for your monitor and make sure you do NOT exceed the maximum color depth / resolution for your monitor, also, make sure not to exceed the refresh rate.

if this does not fix your monitor issue, check the cables for missing pins, freyed wireing / broken insulation.

Again, if this doesn't fix your problem, try the monitor on another PC, and if still a no-go, you may have a damaged inverter board in your monitor, or other componant / wire based issue.

If another monitor doesn't work on your computer, try swapping the graphics card out, it could very well be a dieing graphics card.

I have this GREEN LINE vertically on my DELL LCD MONITOR E176FP 17


c5e83efa-55e9-4b06-8023-89ff1e5850bd.pngDoes it look anything like this? I'm no computer guy at all, but I had that issue with my Dell laptop and the line disappeared completely. How? After watching that bright green line getting Ionger and longer every day I stopped using my laptop for one whole week due to the holidays. After that first week I turned it on to check some random file and to my surprise, the line was a lot smaller and disperse. I had this 2 week long trip the following week so I decided leaving my laptop at home to see if the line kept getting smaller. When I got home from my trip I turned on my laptop hoping the line were actually reduced, and it was completely gone, completely and absolutely gone. I would recommend you to stop using your lptop for 3 weeks or so. Good luck

Vertical lines accross the screen


Vertical lines running down the screen is indicative of a data failure to the screen itself, which means either the screen is starting to fail or the data being transmitted through the data cable is being interferred with. Put a hand on either side of the monitor and give the monitor a light twist....does the line disappear? or do more lines appear...in either case, there is a problem where the data cable attaches to the lcd panel itself. You can try to change out cables, if that doesn't correct it, then the panel may have to be replaced. If you have the option of trying the computer on another monitor that would be the first step in seeing where the problem lies.

Monitor won't come back from "sleep" setting.


Yes it can be, try it on other PC first to narrow down the problem.
Most problems in the Dell are failed transistors, poor solder works, see pictures here for guide: http://s807.photobucket.com/home/budm/allalbums

Colored vertical lines on monitor


Have you unplugged the power cord to the LCD? Let it sit for a minute, then try it. ALWAYS buy a UPS and plug any computer devices into it. Doesn't have to be big, a $50 unit will protect it from dangerous voltage surges.

Sceptre X20G Naga III showing horizontal and vertical lines


Hi...there,

Yeah, there it... It's called a AD board. It that piece of component were you plugged your VGA or DVI cables to it. Panel scratchs repair kits, not recommended. Beside your panel could be already damaged by this problems you had. Replacing the AD board gonna cost you though...any where from $70.00 or more... My recommendation, just get a new one...saved you the headached and $$$.
Have a nice day!

Strange problem


unplug the monitor from the vga , does the osd test come up ,
if not then the circuit is the issue,
if it does then you may have the refresh set too high.
