 Ok thanks, I gathered that. In my case the capacitors between the transistors (the o.22uF caps) both had dry joints and were loose. I replaced these and resoldered the transformers. I have tried other similar NPN transistors but the result is the same. Turns off after one second. I will just have to wait for the correct transistors to arrive in the mail.
However, I replaced the transistors with common MEJ3055 transistors from Jaycar on a 15 inch dell (aka benq) and it works fine, but these do not have the same result in the benq 17 inch monitor which turns off after one second, so again, I think I just need to wait.
