This is the way how to examine what's wrong with your LCD monitors. After you turned it on and the screen stopped working, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,

I have a Dell E172FPb LCD monitor with a black screen and blinking power light, no leaky or swollen capacitors inside, what can I do to repair it? Thanks.


Check out the four transistors (c5706/5707) Emitter to Collector (see picture of the transistor in my transistor album for pinout), it should read open circuit (should be checked out off the board). This is common problem. Make sure to inspect the solder joint in on the board, especially around the inverter transformer pins. Make sure the fuse read out less than one Ohm also.

Check the transistors and the fuse in the power supply/inverter section.

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

No picture on monitor - green power light blinking


There's an internal electronic part/s of your monitor that is cold soldered / defective. I suggest to bring the unit to an authorized service center to properly diagnose & fix the problem. regards

NEC Plasmasync 61mp1 - won't turn on


Its the power supply board. If you cant get the whole board, check your transistors theyre most likely FSXXX-X (part #). Replacing them should solve the problem. And they're only about a dollar each so youll save a bunch too but it requires a little more work.

Power Light Blinking & Black Screen


A blinking blue light indiactes that your power-inverter board is not putting out what it should. It needs an overhaul which may be a simple as changing out the capacitors on the boards.
It could go beyong that to transistors or even a bad bulb.
It will have to be opened up to do that.
A picture may show visual signs of damage. If you can take one and email it to me , I'll take a look.

NEC MultiSync FE2111SB 22in monitor problem


a blinking green light usually indicates no video signal. check your cables, and if you have another computer, try it on that. otherwise, carefully check your vga signal cable, and the connections on the neck board [where the crt plugs into]

Dell Blinking Power Light


Just wanted to say Thank You for the info on this site. I had the same problem as previously posted. When powered up, the monitor showed a fast flash of the desktop and then went black, with the power indicator flashing green. I read the posts, purchased the capacitors and the 4 - 2sc5707 transistors through ebay. I ordered them on the 6th and rec'd them today. I only had one bad capacitor and one transistor that checked bad, but I ordered 5 caps and 4 transistors. When ordering the caps be careful of the height of the caps. I found this to be a problem because I ordered the 50v, 105 degree Panasonic caps that didn't fit with the enclosure attached, so I used the 4 good caps removed previously and replaced the bad one with a 470uf, 50v. 85 degree cap from Rubycon I found among my spare parts. Installed the parts and the monitor is working properly (for the last two hours) so I'm happy for as long as the repair lasts. Thanks again for the info.
