LG 1510S Monitor Issue

[FercHeliX]

Hi
There's this LG 1510S LCD Monitor that had 2 issues, one with the 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 stay on and disconnect 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 Vin of regulators and 3.3 and 2.5 on Vout ?!

please help ... thanx alot.

Regarding the issue with the no signal message not appearing when you turn on the monitor using the power button, it could be an issue with the mainboard. You may want to check the connections and cables between the mainboard and the other components, and also check if there are any damaged or burnt components on the mainboard. Overall, it's difficult to diagnose the issue without more information or being able to physically inspect the monitor. If you are not experienced with repairing electronics, I would recommend seeking the help of a professional technician to avoid causing any further damage to the monitor
