Is LCD worth repairing ?

Archived from groups: comp.sys.ibm.pc.hardware.video (More info?)

I bought an LCD monitor about 3 years ago.

When turned on, a little light will turn green when there are video
signals. When PC goes into power-saving mode, the light will turn red.

Several weeks ago, when I turned on the monitor the light turned orange
with or without video signals. If left on this way, for about 15
minutes, and then turned off and on, it would work as normal.

However, it seemed that the time left power-on with orange light becomes
longer as days progressed. Past 2 days even if I left it on from morning
until evening it did not go into working condition !

Do you know what is the problem, and any remedy ?
