SOURCE: check signal message when data cable unplugged. blank screen when data cable plugged

This problem is most likely to be caused by a bent or broken pin on the CRT video cable at the VGA connector, OR, this could also be caused by a damaged VGA connector on the back of the laptop. If neither VGA connector is at fault, the problem could be caused a damaged (kinked) CRT data cable, or internal damage to the VGA connector on the back of the laptop, though I suspect the problem is more likely to be external, and you probably won't have to disassemble the laptop to locate the culprit...

SOURCE: Light on power on switch keeps blinking, screen blank.

Definitely a problem with the monitor. If you can get the back open then look at the main board and the power board. You will want to look for puffy capacitors. Instead of a flat top it will look puffy like its pregnant.

If you find any like that then you need to replace them with new capacitors that have the same Uf rating and at least the same voltage or higher.

This will take some unsoldering and soldering skills. Make sure the stiped edge gets aligned with the striped edge on the board.

If you replaced them then the monitor should turn back on. If it doesn't then its a screen problem and you'll need to get a new monitor.

SOURCE: hi everyone , ive got a LG Flatron monitor model

Check out for bad caps in the power supply first.

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 LG and other 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.

LG LCD Monitor L1530S problems


Most screens will show nothing or go to power saving mode until the PC is turned on. The monitors need a signal in order to be 'active'.
From your description it could just as well be a problem with the PC rather than the monitor. The easiest way to find out is to connect another PC or laptop to the screen or connect another monitor to the PC unit.

Did you try pressing the Del key or F2 key when you turn on the unit to get into the Bios?

My monitor lg flatron l1730s keeps going into powersave mode


check your powersaving options in windows>control panel>power options

there is a bunch of options in there that could make your monitor go into power saving mode.
also check your video card options and menu of the monitor itself all could possibly contain a sort of powersafe option.

most likely indicated with amount of minutes untill... either power off screen blank or screen saver.

LG Flatron L1710S Monitor stuck in Power Save Mode


Try wiggling the Cord on the backside of the monitor.. Not the Power Plug Cord, The Other Cord that attaches to the PC. Do this once the monitor turns off , grab ahold of the cord about 2 inches from the back of the monitor, then bend the cord to the right, keep bending from the right to the left a couple times to see if your screen comes back, if it does, than you have a Loose connection and this sometimes causes the Symptoms you are receiving.. Hope it helps.
