Hi
There's this old LG 1510S LCD Monitor that had 2 issues, one with inverter board and one with image display (mainboard maybe), the issue with the inverter was that when i turned it on it goes off after 1 or 2 secs. and the problem was with the tuner caps on inverter board, after i changed the caps monitor stays on but there's another problem that if I turn it on by the power button, no signal message does not show on the screen, but if I let it stay on and disconnect by the power cable and connect it again the no signal message will appear, and one more thing...the 12V power is 17V before i turn on the monitor but after turning it on it will drop to 12 volts, and about 5 volts to main ... I have 5 and 4.3 and 3.3 and 2.5, the 4.3 is on one leg of regulators on mainboar instead of 5 volts... souldn't it supposed to be 5 volts on the v in of regulators and 3.3 and 2.5 on Vout ?!
please help ... thanx alot.

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...
