I need help to solve the problem with my LCD monitor. I think it has a problem that some people have already told in this forum: it starts for a second and then suddenly black out forever. Actually there is a very faint image in it. But it was so dark. I have already followed the suggestion to replace the six 470uf 35V capacitors. But the problem remains. Do you have any suggestion? Thanks.

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.
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.
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
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!
my monitor is 17'' lcd...... mag innovision model: LT716s..before was working well but now the lcd monitor don't to turn or either the led doesn't turn or make any sign.... no matter whta the lcd stay blak,,,,,do not want to turn on....
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.
