I got a neovo m-15v screen with a dead power supply.
First it made some ticking sound, like transistor was trying to switch. Measured the voltage form the net (230 volts ok) than after the diodebridge (aprox 300volts) And than there are 2 ?transistors? mounted to a pice of aluminum. Behind these the power seemed to switch on and off.
After a while there blew a service mounted resitor at the back of the circuitboard. And i couldn't measure anymore.
Now i'm looking for a scheme of the powersupply of this screen.
Can u help me out?
thanks in forward.

If issue persists, it is recommended to contact your monitor manufacturer for further assistance.
Try ordering a new power adapter from Neovo. Call them up. It could't hurt. Apparently adapters are tricky items. I have no idea how much they cost, but if its reasonable it would be a fair tade for the nuisance you are dealing with now.

Call the service dept. in the above post. Tell them the model and serial number of your monitor and order a backlight inverter board(approx. $35 plus shipping). Open up the monitor and plug it in, should fix the problem. This problem could also be caused by one or more backlights(small flourescent tubes) being bad. I just fixed a Neovo F-417 display by replacing one of the backlight assemblys. I also just fixed a Neovo E-17DA monitor by replacing the inverter board.
