My monitor is an LG L1932TQ-BF. as I was reading the screen the brightness
flickered and the screen went dark. If I power down and then back up, I get
a very brief well lit screen with "normal" text showing. It lasts less than
a second. The power light comes on normally and changes color when a video
signal is there.

I have not had the need to get into the guts of an LCD monitor.

What sort of precautions are to be observed when replacing the light(s)?

I have fixed almost everything else electronic in the past. I have done CRT
TVs, PC's, Microwaves etc. What I need is a road map before I open it up.
Are there any good sites with directions and are there any preferred
suppliers of replacements.

I know I could just Google this but it is always better to get advice from
someone with hands on experience.

I could run out and get a new monitor, but as a retiree I have more time
than money.

Charlie,

While I'm no expert on monitor repairs, from what I've read the problem
is more likely to be with the lamp power supply rather than the lamp(s)
themselves. They are often some sort of switch mode supply on a small,
separate board that the lamps connect to. If you are lucky, you'll have
bad capacitors, if less lucks, a bad coil or transformer.
