Having problems with your Mag Innovision InnoVision LT 765S 17" Flat Panel LCD Monitor ?

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

\015 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!)\015\012\015\012Thank you!\015\012- Jolie\015\012Westfield, IN\015

Answers :

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.
