Mag Innovision 765S power supply light blinks and monitor power led blinks and no picture

Greetings! We have a MAG Innovision 765S monitor that was no longer producing a picture and I had given up on it until I started reading some user comments on this web site. When we plug it in to the computer and power it up, there is no picture, but the power LED blinks and it makes a regular clicking noise like it's trying to turn on. We notice that the power supply, which also has an LED, is also blinking on and off. So that leads me to believe it may be a power supply problem rather than a monitor problem. Any thoughts? (don't know where to buy another power supply!)

Thank you!

    I confess I'd have to take it to someone with the tools and the talent in order to accomplish your suggestion, which makes sense. It is not easy to find places where they repair monitors. When I took the monitor to Best Buys, their response was that they would have to send it out, and due to the high price of labor, I may as well think about buying a new one instead.

    I have a mag 578 and the power "supply light" is solid green, im guessing its the light on the cord. anyways the monitors power light blinks like so, long green, off for 1/2 a second then back to long green. long green is about 2 seconds. The monitor was given to me and ive already torn it apart and searched for burnt board and loose cables but nothing. would love to fix it as its the same size as my current crt monitor :)

I'd suggest looking at the mainboard. I assume the blink is rapid? A slow on, followed by a short off and back on again is normal. The fast blink thing is a mainboard issue, and the absence of blink (or light) is power "supply dead."

There is a problem transistor on the mainboard that seems to be the problem most of the time. Replacing it takes about 5 minutes if you have the tools and the talent, and the parts cost under 3 bucks at Radio Shack. Just pick up a pack of NPN switching transistors and de-solder / solder your way to a working monitor. There's usually only one on the board, so it's easy to spot.

There are several Mag monitors that use external AC adapters that plug into the VGA cable. Look on the blue connector and you should see the hole where the adapter plugs. The adapter is 12v 5 amp such as this one.

check your cables especially to the power supply or check your outlet if it is giving the complete consumption of power to the monitor.

I dont know about capacitors or regulators i just need to know how to turn this thing on.

on the specs from ebay I see you need a 12v dc 5 amp ac power adapter .
normally they have an led , but if you can't get power you will have to verify that you have the 12v at the tip, you will need a multimeter or 12v bulb connected to the end.
if your getting power then the panels circuit is at fault.
talk to a local geek about checking it out.

Mag Innovision 765S Screen Flashes on and off.

It sounds like it is trying to re-synchronize it self and not going back the the default setting. Compare the resolution of the game to your monitor capabilities.
