    I have the same problem with a sylvania model 568. I removed the rear cover and screws holding the circuit boards. When the power is connected and video source attached I remove the larger of the two ribbon cables. The backlight then illuminates and when the ribbon cable is replaced I have video until the video source is removed. I am unable to locate a schematic to troubleshoot this. any suggestions would be appreciated.

    I had the same problem with a dell monitor. the problem with that one was The transistors on the back lite inverter board. I don't know if this helps or not. Just a thought.

The monitor will not turn on. When power button


First--was it working?
Did it suddenly stop?
When you see the LG logo, then it goes away, does the power light turn from green to amber? Sounds like that doesn't happen.
So--if you are getting a signal, you should see something.
If there is no signal, then the power light should change from green to orange.
With no lights at all, I suspect a faulty monitor.

Monitor problem


The power light is flashing green can indicate start/restart of the power supply due to shorts circuits or failing power supply due to bad caps, look for bad caps with bulging top first, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

The power supply in the monitor is probably broken. Take it to a repair shop or purchase a new one. LCD monitors have become very inexpensive these days.

Falshing green power biutoon.


Verify all cables are secure, try reseating them. If the power led continues to flash, this usually means the power supply in the monitor is bad.

I had the same problem. power led would flash green for a few minutes then the monitor might come to live. the problem was multiple bad G-LUXON capacitors on the power supply board and inverter. the monitor is full of them. just search online for bad caps and they are near the top of the list. replaced them and it came back to life.
