Hi, I wonder if anybody can advice on this
The monitor main problem was a flashing power LED .
I did replace the two bad 5707's the other two checked OK
The bottom CCFL SMT 4431 was completely fried and fried the trace too. I did manage to replace it to find that the small 3 leg transistor (if not mistaking) right next to it is fried too so I replaced it. the back light came back alive while the top back light stays off which was really weird !!!, If I bush the start button the top light will come on too not as bright as the bottom one. If I push the button to turn it off just the top light will go off while the bottom one stays ON. So I removed the SMT 4431 that control the bottom CCFL and run a jumper from the drain on the top CCFL to the drain on the bottom SMT 4431 as showing in the image and the monitor works just fine now – any ideas to what damage this will case ???

But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
