This is a common problem due to capacitors in the inverter circuit going bad. The inverter provides the voltage to light the backlight, so the lamp is usually not the problem.

If you open the case on the monitor (sometimes that's a challenge all by itself) and follow the wires from the backlight to the circuit board, you'll find the inverter circuit. There are normally a couple of transformers (they may be small square cases or round coils of wire on black or gray forms), some transistors, and the infamous capacitors. The caps are small cylinders with printed values on them, like 4.7uf, and also a voltage rating. Most of these are values you can find at Radio Shack, so if you or someone you know has soldering experience, you can try changing them. Stick with the original capacitance value (the uf number), but try to get a slightly higher voltage rating if you can. The voltage ratings come in standard values, like 16 volts, 25 volts, etc. The higher voltage parts will be a little bigger but should still fit. They go bad because the rating wasn't high enough to begin with. But it saves the manufacturer a little money on each unit. Make sure you observe the polarity of the capacitor (plus and minus, with some kind of marking on the circuit board to show you) when you put in the new ones.

Have a Mag 19" monitor, model LT916s. Screen is


Sounds like a silly question but have you checked the fuse? If it isn't that then it sounds like a problem with the power board. Check it for burn marks and bulging electrolytic capacitors (they're the little round tube like things that stick up), also check any fuses on the board. If it's the caps or a fuse then just replace them, if something else is burnt out then you'd have to replace the board but you might not be able to find a replacement since it's old.

Monitor reads no connection


1. Check the cable connection to your PC. It might be disconnected.
2. If your have more then one cable input on your LCD monitor(VGA or DVI) check if you selected correct input; digital for DVI or analog for VGA.

Good luck!

Mag problem


Hi..there,
The lamps has nothing to do with it... what you need a new backlight inverter or repaired it by replaced a couples of bad capacitors... Sound easy... right! Not so... It's not always the caps problems.

MAG Innovision LT916S monitor problem


Hi this is the way how to examine what's wrong with your monitors. After you turned it on and the screen went black, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,
Tan

MONITOR MAG LT916S


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!

How do you open a Mag Innovision LCD Monitor LT916s ?


There may be some interior support hooks that keep it together.  look for metal clips between the crease of the front and rear pieces.  Definitely use caution with opening as you do not want to force pressure against the screen.
