I have a dell 19" inch lcd monitor and when turned on it shows the desktop of a second then the screen turns blank. The power light on the monitor stays on. I tried a different cables an a different computer but still same. I dont have a warranty but want to fix it, if i knew what the problem is??
I had same problem, fault was traced using a multimeter set to diode measurement, i found that one of the high power switch transistors in the inverter side of the power board was short circuit (there are four in the same area sticking up from the board, not surface mounted). normally they should measure 450 ish but when they read 0-010 its gone, pulled it out of circuit and remeasured it, gone, replaced and fixed.
Unfortuneately this is nothing that is going to be fixed over the internet. Do you see anything at all when the screen goes blank, an outline (very, very dim) almost like a ghost image, on the desk top?
Sounds like the inverter on the lcd has gone out. It would be a lot cheaper to get a new monitor than to fix this one.

hi, try to open the monitor back cover, then look at some of the capacitors in power supply modules if anything looks normal maybe the problem on it are the socket of the flex,
try to unplug aligned and plug it back.
hope this will help......thanks
The monitor you have has bad components on the circuit boards inside. This is a classic problem with all LCD monitors. I rebuild them on a daily basis so I recognize the symptoms. I would suggest finding someone who can do component level repair on the circuit boards inside. I also suggest not trying to repair yourself as there are many breakable components to them as well as components inside that do not like static electricity discharges.
franh, Typical of a lcd/fpd monitor! There is nothing you or hundreds of others can do to repair it all by yourself. I have repaired 3 monitors and helped tutor 2 others on fixya with their monitors. All had same exact symptom as your monitor. I need you to do a simple test for me. With failed Acer monitor near to your Fully Booted PC with a known good desktop being displayed on back-up monitor, quickly swap out the monitor cables from the back of the PC. Keep touching the CTRL key on you keyboarb every 30-50 seconds to keep the PC from sending out sleep mode command to monitor while doing the reconnect of acer to your PC monitor output port. Make sure the Acer also is connected to a live wall outlet/power strip. Turn on the Acer and note what happens. If screen shows a sharp clear image for a second, then goes black, do the following. Get a bright flashlight and shine it on the screen from a distance of 1 or 2 inches and tell me if you can see the desktop display. get back to me with your observations. I'm louie12fix on fixya or [email protected] aol.com.
Do you have the video set to a range that this display cannot handle? Try rebooting into Safe Mode and set the resolution down to 800x600 or 1024x768 and see if it that will get you back. If so, then look up the specs of the display and set it no higher than it's max.
If it physicaly powers OFF, then you probably have a power issue.
Unplug the cable from your PC, if the monitor shows a test image, the monitor is fine and the problem is with your graphic card.
If you dont see nothing on-screen after unpluging the cable from the PC, then the monitor in damaged. Send it to repair.
