Hi, Try this link http://www.pchub.com/uph/category/43/LCD-Inverter.html In some instances inverters for other brand/model will also work for your Mag. You just have to match the part number. Good luck and kind regards.

I have a mag innovation flat screen computer monitor but I need the power cord for the monitor it is a LT717S model # 700P made in 2006

The power lead you need for this monitor is a standard EU 3 pin. you can purchase these from any good electrical or computer store.

The look like the old Kettle plugs if its of any help

Screen went black/won't power on

This is a common problem

The first step is to check the fuse on the power supply board. Next, disconnect the inverter board to eliminate the possibility of it shorting down the main and or power boards. Be careful as the inverter board supplies high voltage to the cold cathode tubes (backlights) and it bites HARD. If you disconnect the inverter and the power led comes up then replace the inverter board. (The screen will appear blank because you have no backlighting). If the power indicator still fails to light you need to suspect the main board first before the powwer supply board. The main board tells the power supply board to come on. You need to check the trigger from the main board to the relays on the power supply board. Also check the power connector to the main board because you should see +12V and/or +5V on at least some of the pins. If no power on the relay triggers then replace logic board. Then replace Power supply board last. Or buy a new monitor!!

I don't have the origional plug but I have an identical one, but my monitor won't turn on.

You more likely to thave power supply problem.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Mag Innovision LT982s screen problem

Hi,

Based on your post/description, I will initially suspect the inverter and/or the CCF Lamps since as you posted "dim screen picture" indicating that there is ** backlight(s) and/or it is **t receiving power from the inverter.

If the unit is relatively new and under warranty, it may be to your advantage to have it replaced or seek the services of their Service Center. Should you want to do a DIY, it would be required that you be familiar with electronic circuitry and components, use of a DVM and a soldering iron and access to a service manual or at least a schematic diagram.

Incidentally, there are k**wn cases where similar issues could be resolved if you try lowering your display properties (resolution and refresh rates) but that would also include the powerlight changing colors.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Below is a re-post of my response to similar issues.

Mag Innovision LT776s Model 780

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!
