HD19A / 19-Inch light flickers but no display

Check for blown capacitors on the power supply board, this is a very common problem with LCD monitors. Here is a link to a web article showing what to look for. The second link is to a source for capacitor repair kits for that series monitor.

Disconnect the lcd from the computer. Turn on the LCD and see if it still flickers fast. If it doesn't then go ahead reconnect the lcd back to the computer. If its still flickering, then go ahead and hook it up to another laptop or desktop. If it doesn't flicker on another computer then that means there is a problems with the video card on the original computer.
If it still flickers then that means the lcd is bad and would need to be replaced.

Hi there. Try to remove and reseat your video card first... maybe there's nothing wrong with it actually...

But if you check the on-screen display, like the brightness controls in your lcd monitor blinking... then you need to have it repaired or replaced.

Hope I gave you an Idea.. ^_^

Time for a new monitor.

It could be the Monitor, the VGA adapter, or the PC itself. If you power on the monitor without anything connected to it, do you ever see anything on the display?

If not, it is probably the Monitor. If yes, it is likely the vga adapter and/or PC.

Cut and paste from another site:

I was called to repair similar incident last week. A Compaq box (don't remember the model) with a 'smart' usb keyboard. By this I mean that the keyboard had a row of what I'll call hot buttons. The client had pushed a button with a moon on it causing the monitor to go into sleep mode. I suspect that whatever key you pushed had the same effect.
After plugging a known good monitor into the faulty box I verified that the box was OK. This left me to think the monitor itself had a problem. Plugged the suspect monitor into a known good machine.. and it worked fine!!!
Set machine and monitor to original configuration and still had no video. Decided that the monitor was too smart for its own good and maybe there was something in the monitors menu. Pushed and held the 'menu' button on the monitor for a few seconds and menu comes forward. Green power led also comes on (surprising me) so I powered up the computer and lo and behold the problem is fixed!

its cheap buy a good one!!!!!!

I have had similar problems. It would appear that the power supply is at fault, not the monitor.

It is the same problem I experienced and now it suddenly stopped and dead.

what the manufacturer of the unit has to say about inherent design fault which they are liable under UK consumer law to rectify within 6 years

And incidently who are manufacturer to this Licon make is please
