    my monitor is lg 17"inch

  • Mandee Jan 11, 2009

    I have an HP lcd flatscreen monitor, 17" I believe, it happened first about a week and a half ago, the power light keeps blinking blue every time I restart the computer, I cannot see a thing. I've resorted to using an old school big, clunky monitor that has NO sound on it! I need my monitor back, I've even rebooted my computer back to its original state. Any advice? HELP!!

    Same problem. I think it is something that is going to have to be sent back in though. I don't think its a simple settings issue, its most likely a bad chip in the monitor or something in the power supply within it...

If there is a flashing led on front of the monitor, 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.

1 The 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 occurr suddenly are a blown capacitor on power board, the inverter board powering up backlight lamp has blown, or a fault on main lcd controller board.
check also the video cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

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

If under warranty contact manufacturer to find out a service point.

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

• You can check if the product is working properly using the Self-Diagnosis function.
• If a blank screen is displayed and the Power LED blinks even if the product and the PC are properly connected, perform
the self-diagnosis function according to the procedures below.
1. Turn the product and the PC off.
2. Separate the signal cable from the product .
3. Turn the product on.
4. If the product is working properly, the message appears.
In this case, if a blank screen is displayed again, make sure that there is no problem with the PC and the connection. The
product is working properly.

Is a blank screen displayed and does the power LED blink at
a 1 second interval?

turned on.

Monitor : no display and blue led light is blinking


The power supply is the first thing that the 110v electric line goes into. The invertor is the next item past the power supply, or sometimes contained within it. I do not thing monitors are a DIY repair.      First substitute a different monitor to confirm that it is, in deed , the monitor and not the video card.

Monitor power light is blinking .but monitor is not displaying anything after 4 hr monitor blinking light is become slow and when restart the monitor is displaying after 4 hr please help me


We had the same problem with a Princeton VL1918 19" LCD monitor. Usually its a capacitor problem. If this is the case you might need to take the monitor apart look on the power board for the bulged capacitors and pull the numbers off of the caps. Go to a radio shack or find an electronics store in your area, get a soldering gun a soldering vaccum bulb and a wet sponge. Make sure you plug the right post into the right hole before you solder it. There is a Negative and a Positive on the caps. The wafer board should say where the negative whole is, also the capacitors on the board will show a negative side. Just use a pen or a sharpie mark for the negative posts, there may be a few caps that may be bulged. On the Princeton I just fixed it had three of the same capacitors 470uf at 25volts. Make sure you get the right caps or you have the potential to mess your monitor up even more than it already is. Inspect all your caps on your power board, Im sure there will be some rather larger ones and some small ones, if they look bad or you even suspect them of being bad REPLACE THEM. Capacitors are CHEAP so replace them if you suspect them of being bad. Solder new caps onto the board and then clip the extra cap posts. A note on safety. PLEASE BE SAFE DESOLDERING OLD CAPS. They can be charged in some cases. Just don't cross the posts when desoldering. The new ones that are packaged should not be charged but safety first ALWAYS assume a capacitor IS charged at all times! You will live longer if you take that approach!

I just replaced the relay on my second-hand NEC2010X . It would go out after some period of time, but come back if I unplugged it and then plugged it in again. It finally died altogether, but when I replaced the relay, it worked fine. Apparently this relay is the weak link on many LCD's (probably the only moving part in the whole thing). So open it up, unsolder the relay, and put in a new one.

Monitor stops display


most likley the monitor has an internal power supply failure, generally the cost of repair could be higher than buying a new one.If your monitor is still in its warranty period contact the manufacturer,if not do you know of a local tv repair shop that provides free estimates to confirm cost of repair vs. replacement?
