My LG Flatron 1710S computer screen doesn't have any power. Sometimes the power light will start flashing but most of the time it stays blank.

check whether ur cpu is working fine

i am also having the same model,but mine was just power light blinking and screen is blank even not starting after long hours.

You may have capacitor failure (bulging or leaking) in the power supply (very common problems in ALL monitors), failed transistors or transformers in the back light inverter circuits, or bad lamps due to poor solder connections, poor solder joints on PCB. You need to open it up and look inside, post back what you see so we can guide you further. See example of failed monitors for guide: http://s807.photobucket.com/home/budm/allalbums

are you getting a check signal cable message? any on screen instructions?

try the cable, if it works on another monitor, then sorry to say but your monitor is fried

t certainly seems like the monitor is not getting a signal. Did this happen after you changed something, or just on normal boot up?
It could be the video card that has failed.
Also, check the pins on the connector; sometimes they can get pushed in.
If you can, try swapping out the video card or use the monitor on another computer.
Good luck,

go to hell

change the power section capacitors..

Hi...there,
Well, It's time to retired this LCD... Your panel it busted! Treat yourself a new monitor... Happy holidays!

The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

• Video cable.
• Video adapter on PC (sometimes integrated on motherboard)
• Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

When the picture disappears again take a flashlight and shine it in the bottom left hand corner where the Windows Start button is located. If you can see a faint image then your back light is failing. If that?s not the case the next step would be to attach another monitor to your computer to see if the problem disappears. If it does that points to the monitor, if it doesn?t then we need to take a look at the computer itself. Let us know what you find out and please don?t forget to rate this posting.
