HOW TO SOLVE THE GREEN & BLUE LIGHT STILL BLINKING

green LED blinking but no display, when disconect VGA cable from CPU than monitor displays cable disconected. CPU vedio card is ok

(Please be advise that if you don't have the knowledge, the proper skills and the right tools to open the back cover of your monitor and replace its part...don't risk it...
Otherwise, bring your unit to a credible technician and avail of warranty if there is any.....) If you have guts.. then do the following steps..

You said your monitor will blink but no picture display... well, there are possible reasons why this problem occur..

1. Open the back cover of your monitor..Check the power supply section for possible loose connections and blown capacitors.. Resolder any loose terminal connection on the pcb. Check for any blown capacitor, replace the capacitor with exact value, and also replace any bulging capacitor..If you have successfully replace the parts you can try to turn it on and connect the vga cable in it to the video card of your computer. Turn on also the cpu, if the monitor led turn green and the display came out..that fixed it.

2. In case you have successfully repaired the power supply section and the led of the monitor stays green.. then the problem will be in the inverter board section....Turn off your monitor... open the back cover...on the inverter board section.. check and replaced burnt or overheating high voltage transformer..if one or more of this overheats, it is enough to affect the supply current from the power supply section and that may cause to blow your capacitor...If the ballast transformer is working fine the last thing to check is the backlight inverter (the light that illuminate causing display in your monitor) Replace any busted lamp.. that should fix the black screen on your monitor. ..

your power supply is probably bad. open the case with it unpugged and look for leaking or crowned capacitors. most electronic repair shops can replace them for you

Hi,

There are No display in your system .Pls remove Power cable from CPU and again plug it and start your system.If display still not comes then pls remove RAM chip from slot in the Motherboard and re-install goods one and check it.if still display not come then issue with Motherboard .Its detter call vendor for repair the Motherboard.

LG 700E monitor's power LED blinking continueously and there is no display solutin ........

1. cpu problem. why because of there is no signal output from cpu to monitor. the led blinking means there is no vertical, horizontal signals from cpu to monitor.

2. your monitor connected to another system.

3. neck board dry points.

4. cheak the display cable. 13&14 pins are horizontal, vertical signals.1, 2, 3 pins , R G B , 6 ,7, 8 pins R G B ground ( coaxiler cable used , meshed wire is ground )

I thing it is the problem of horizantal output transistor.that is placed on hitsink of eht big in size.Or check vga cable.
Hope this be of initial help/idea. Pls post back as requested, how things turned up or should you need additional information.
Good luck and kind regards.
