| 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 | |

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. |
