Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After that, you need to check 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. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. 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.

Why wont it turn on


Most common problems with modern LCD computer monitors and LCD,LED tvs are it power supply boards have dead and dying capacitors components parts on the power supply boards.That the board u alway check it first and throughtly for dying and dead capacitors components parts.That the board where the tvs or monitors A/C power cord plug in it.U have all the basic tools also u can do soldering works and understanding basic electronic components.U should by replacing these dying and dead capacitors components with no problems at all.But when u are replacing all these dying and dead capacitors components parts that are bulging up and busting out of it normal cylinders bodies.Replacing these new capacitors components parts alway up the voltages higher in these new capacitors components parts like 5 or 10 voltages higher will stably the power supply board alot better and don't put out to much heat for the capacitors chemicals make up to handle.If u can not do basic soldering works and have all the tools or understanding basic electronic components theories.Tries websites like Ebay.com,Shopjimmy.com to buy a whole new refurbish power supply board for the replacement.

LG E2350 monitor will not start up. Have unplugged and rebooted but still will not start up. 6 months old. Did this 3 weeks ago and a week later started to work.


Hello,

You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where in the power panel board, but you need to open the back cover of the television to enable you to check for the fault also be careful in solving the problem because it contain high voltage, if otherwise the power supply board is dead, you know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

I hope this help in solving the problem......

No start ,dead


Hi alonzot,

Here are some basic steps that will help you fixing the problem.

I'm assuming that your unit is dead set without an standby LED light and your outlet is live.1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I would advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit the linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

4.If you see that the fuse is intact , don't attempt to touch anything because there some fatalcomponents stored electricity enough to hurt you with a simple mistake only. I would advice you to look for a professional to troubleshoot the power supply. If you want to repair it yourself make sure that you have necessary tools and test instrument. First check bad solder joints(re-solder all cold solder), leaky electrolytic capacitor(sometimes it has bulged at the top but not all, you better have a capacitor checker), open/shorted regulator transistor/IC(mounted in heat sink), open fusible resistor (caused by shorted regulator Transistor/IC), shorted zener diode.

You may also replace the power supply board, try online like ebay.com and shojimmy.com.

Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.

Hope I helped you.

Have a nice day!

Thanks for using fixya.

My hp monitor is totally black it was working last night. i tried to unplug and replug it in and it came on for a few seconds then went black again


A lot of time people have the impression that the monitor is not working when in fact the computer is not booting its lighting up but nothing else so its stays on a black screen.


One way to know is by opening your speakers or plugging head phones, if you hear windows open or any windows sound the problem is the screen.

You can also unplug the screen from the pc and turn the screen on most of the time the screen while show a disconnected warning on the screen if that comes up the computer is defective.

Dell 1704FPT just went dead, will not turn on not even yellow light on power button - just seems to have died. Is there a way to reset? or is it time for a new one?


First you need to troubleshoot a little. You should first try another power cable for the monitor, if that doesn't help, you might be able to open up the monitor case and check wether the button is broken. If the button is broken, you're going to have to improvise a new one, since new buttons aren't really being sold. If that isn't the case, or if you can't open up the monitor, take it to computer shop, these things are easier to fix if you can look at it. I hope this helps, Yannick.

Nec multisync lcd 2080ux no raster no power indicator light.


If u a tech, try checking the PSU of the monitor for blown fuse or dead driver element ( typically a FET, Power transistor or an Hybrid chip) . U need to take the monitor apart, if unfamiliar, get it to a service tech.
