Hi, i have this monitor with 2 second to black. It use 12V DC power supply.

I check CCFL lamp with tester and they are ok. Here is the picture with voltages.

When monitor turn off lamp i can see picture with my flashligt. I check visualy caps and they look ok to me. I try tu change 2-3 of them but no differance.

I also check the secundary wining of transformers and they are not shorted.

Please help

ok, now i noticed that i did not test one lamp at time. Now i discovered that one of the lamp is dead.

i replaced the connector (purple with blue) and monitor working (with one lamp down) but working.

maybe there is IC monitoring only one connector for lamp feedback and when i connect working lamp in that conector IC did not pull it down.

Yes that sometimes happens on these smaller monitors. Maybe you can get a replacement bulb from a cheap faulty even cracked 17 inch monitor. Although it is difficult changing a bulb.
