Question about Envision 19" Widescreen Flat Panel TFT LCD Monitor
The on light is blinking but the monitor will stays black
The monitor is probably on protection.
To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.
If it is computer fault and no video signal , then test:
If it is monitor fault , then the monitor is on protection.
When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.
If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults that can occurr are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.
Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing statebecause of the video cable.
Try moving the video cable, and if the cable is not built in, then also try a replacement cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

A blinking blue light indiactes that your power-inverter board is not
putting out what it should. It needs an overhaul which may be a simple
as changing out the capacitors on the boards.
It could go beyong that to transistors or even a bad bulb.
It will have to be opened up to do that.
A picture may show visual signs of damage. If you can take one and email it to me , I'll take a look.

it sounds like your mointer is ****, i highly doubt the game caused it. try another mointer, or sell that one on ebay and buy a new one

The blinking power light is a sure sign of a power supply failure. The heat buildup in the case causes parts called capacitors to blow and short out the power supply making the power light blink. Go to our web site at:
www.ccl-la.com/badcaps.htm we have pictures of what blown capacitors look like. Now open up your monitor and ook at the power supply. Replace all of the caps that look like the pictures and you should have a working monitor again. The replacement caps will need to be high temp which is marked 105c. The values that you need to get will be marked on the sides of the bad caps you take out such as 220uf, 470uf or 1000uf plus a voltage rating. The caps can be ordered from several places on the internet or we can supply them for you. Do not use caps from Radio Shack they are not rated for this type of use and will blow out in a few weeks of use. When you replace the bad ones be sure to insert them with the polarity stripe on the side going the same direction as the old ones come out. If you have any questions just ask. If you don't want to do the repair yourself we do offer a repair service for $30 + return shipping.
I hope this helps, if so please rate our solution.

It has shorted out transistors in the inverter circuits, also look for cold solder joints, fuse.
If you are going to DIY and have proper tools and know safety precaution then please read on:
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
