Question about Computers & Internet
Hi, I have the above monitor which I brought off eBay and picked up from the blokes office. When I plug it in the power light comes on and if I touch the menu button they light up but the screen is totally blank. Does this sound like a back light problem or a more serious screen problem ?

SOURCE: Screen goes blank
Hi jkm007, Sounds like the back light inverter board is bad. It's a very common problem. LCD's use four small cold compact fluorescent bulbs to back light the display. (thats what gives the LCD it's brightness allowing you to see it) The inverter board runs these lights and when they go bad they will typically show symptoms like you have or the monitor power light comes on and you have either no display or a very dim display. If you ever have one that has no display but the power light is on you can check by shining a flashlight directly into the LCD from the front (right into the screen) if you can see an image then it's either the inverter board (most likely) or the CCFL bulbs have gone bad. The inverter board and CCFL's are replaceable. Good Luck, El Duderino

This problem is most likely to be caused by a bent or broken pin on the CRT video cable at the VGA connector, OR, this could also be caused by a damaged VGA connector on the back of the laptop. If neither VGA connector is at fault, the problem could be caused a damaged (kinked) CRT data cable, or internal damage to the VGA connector on the back of the laptop, though I suspect the problem is more likely to be external, and you probably won't have to disassemble the laptop to locate the culprit...

I assume the monitor is still plugged into the back of the system? If so, do you get any beeps which can denote error codes for the system? Put your ear to the monitor, any strange whinning noise?

You have a monitor with a common problem. After a few years some LCD monitorswill blow a power supply. The problem is caused by parts calledcapacitors overheating in the confined space of he monitor. If you aregood at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htmYou can take the back cover off your monitor and look for the bad parts,replace any that look like the pictues and your monitor should workfine. The capacitors do need to be installed with the correct + and -connections, note the stripe on the old one and insert the new one thesame way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.
