Your #1 suspect: LCD inverter, a circuit which supplies white light to the screen.

Step 1 (this is a workaround only)
Attach a regular CRT to the monitor port on the back of your system. You'll be able to use
the computer as before using the CRT as your display rather than the system LCD display.
Reasons to do this sooner rather than later:
(a) flickering with a frequency of 2 seconds is likely to cause headache.
(b) your LCD inverter is about to die.

Step 2.
Use your computer software (you didn't mention what OS you're running), hunt up any/all
vendor-supplied video diagnostics for your system, meaning any diags that run at any of three
levels: (1) BIOS (just above hardware level), (2) MSDOS, (3) MSwindows. The diag most likely
to help will be a BIOS video diag - though its possible that all video diagnostics may pass
without detecting an impending LCD inverter failure.

Step 3: Download the manual for your motherboard & computer system (they're probably from
different companies, with different web sites - you didn't mention the make/model/BIOS version of your motherboard, on your LG R405 computer). I went to http://www.lg.com
but couldn't find any laptops manufactured by LG - they're heavy into cellular telephony, though.

Check AC Adapter for voltage output using multi-meter. If Adapter is GOOD, remove battery and try again. Does fan run? Does screen show Flash Screen? Please advise in detail.

Lg r405 laptop screen flickering


most likely a loose connection if it is flickering.. if there are red squiggly lines usually means driver issue.. and if there are blue banding lines, typically means the chip is overheating/desoldering.

Brand New laptop, won't start


Try taking the battery out before you turn it on. Have seen completely a dead dead battery keeping a laptop from starting up. Does the hard drive activity light flickering? If it is you can try holding down the Function button (FN) and there should be another button to hit to switch between LCD\CRT.
