My LG lcd monitor Flatron L1530S goes flashing blinking when i turn on the power button,and the power gone off,

Hello, If is goes to sleep when you turn on , it has a power supply problem.

LG W2353 dvi power saving mode
how to fix ?

To un-lock the OSD - press and hold the MENU button while the monitor is off and then press power button to turn the monitor on.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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 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.

It sounds more likely to have power supply failure if you hit the power button and it does not turn on.

HI,
your monitor is not working properly, bcoz monitor data cable no connected properly into the System or any internal problem in your monitor.

Thanks

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?

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,

shorted components on the circuit. send it to a repair shop if you don't have experience on electronic troubleshooting!!!

Smacking the monitor works for me. Really.
