Monitor Problem (No Signal)

Hi!
A friend of mine gave me an old monitor (hitachi cml158xw) which has a problem.
When I connect it to a desktop, the monitor powers on (power light turns green) but I get only a blank display. When I disconnect the vga cable, I can see the known messages (no signal, etc) and the light turns yellow. If I reconnect the cable, the light turns green again.
As I presume, the monitor receives signals from the vga card (I've also checked the continuity of its pins, and it is ok).
Also, because I can see the info messages (e.g. no signal) I think that the fluorescent lamp is ok..
I've also checked (visually) the monitor's board and I didn't see any burnt caps/diodes/resistors/etc.
Do you have any idea what to check next? What would be the fault?
Any help would be very much appreciated!!
