Syncmaster 920NW wont show any signal until heats up

[shaun_shaun]

Currently my Syncmaster 920NW not showing any VGA out signal until its warming up for nearly 1 minute. this issue normally happens after the monitor turn off for few hours..

First I thought this might be a issue with my VGA or Motherboard, then I tested monitor "Self-Test Feature Check" by removing my LCD from my VGA. then it didn't show the "Check Signal Cable" signal. usually this issue will fix after it LCD warms up (nearly 1 minute). And I m not currently having any other LCD issues while using my PC .

This LCD is 3 years old..

anyone can help me with this ??

Replace the monitor, unless you are also taking about when the PC is off. If you shut off the monitor while the PC is on, does it also happen?
