It does the same when attached to another PC? Otherwise I would look for caps with domed tops.
If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), 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 monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Cant get LG HBS-250 into pairing mode


Make sure the headset is off when you hold the call button for 5 sec. And don't stop holding it when you hear/see something happen after the first 2 sec. Keep holding it for the full 5 sec. The blue light will become solid which means it's in pairing mode.

A vertical white line appears on my LG L1520B 15 monitor


This is a horizontal sync circuit gone.
In English, probably cheaper to replace than repair.
Wouldn't hurt to get a quote if it is free.
