Fujitsu-Siemens P15 TFT power/picture problem. it take time to turn on.

My monitor has recently developed a problem when being turned on. The power light flashes orange in a steady rhythm (approx 1 second on, 1 second off, repeat) and no picture whatsoever appears. The PC boots normally, I can "guesstimate" the user login location for WinXP on the welcome screen, and sometimes can hear the startup noise through the TFT speakers (very faintly as the light pulses on). I have tried 2 AC Leads, 2 analogue cables and my DVI-D cable as alternate inputs, and the mainboard graphics too, but still no signal. The monitor usually puts up a grey box saying "No Signal - Entering Sleep Mode" when no signal is detected, but this has not appeared. A second monitor on the same graphics card, with the same cables shows a picture, as it does on the mainboard Graphics card. Sometimes, I can jiggle the leads in their sockets, and eventually (after many hours) it appears to solve whatever the problem is (or just wishful thinking after hours of frustration), and return the picture. Sometimes when this happens, it is a normal start/power-up sequence, but sometimes the screen is totally whited-out, and I have to cycle the power to get a "waxy", striped effect which disappears from top to bottom as the real picture appears. Any help or ideas would be welcome, but for the meantime, I'm having to buy a new TFT tomorrow, as leaving this one on 24/7 to prevent the problems and frustration, is not really a long-term solution. Thanks. When i turn on my LCD its blink the orange light and automatically turn off and there is no any picture appears just a dark screen this process continued for few minutes and then it appears the screen, something I diagnose the problem that in the cool whether and atmosphere it take much time to turn on rather then worm atmosphere, might be its capacitors are not working correctly but not shore. Can you help me to overcome this problem?
