It may be a bad connection in the display adapter. Try another adapter. Beware, some after-market adapters are not wired correctly.

I would just replace them because monitors are very cheap right now, only about $100 for your size on sale at Fry's electronics.

Hello, I had the "short long short" blinking led problem with my 23" ACD after a power outage which left my screen blank and my cheek wet with a tear for my baby. I read somewhere that a guy was getting a 1 volt reading on the middle pin of his damaged 90 watt power block. I figured maybe the display might work if I could somehow block the middle pin. So I cut a small strip of paper wide enough to block just the middle pin and long enough to cover both sides, folded it to look like a "W" from the side. I then carefully pressed it into the brick receptacle with a toothpick leaving just a little slack so it would not tear when I pushed in the small white plug. It was a bit of a tight fit but guess what. IT WORKED! I am now enjoying my beloved monitor anew and saved $$$ on replacement brick or repair. If you want to try it and you feel you’ve nothing to lose, make sure you cover just the middle pin (both sides) and you may have to try a couple of times. It worked for me. I hope you have good luck too. Regards, Moozleredit December 2016. Still working after 7 years. ***CAVEAT AND WARNING***Use this fix at your own risk.A faulty voltage regulator is probably the cause of failure. Voltage regulators can start a fire if too much voltage is applied.Bud Martin's post below describes the electronic component failure that causes this problem. Thank you Bud.

Internal Fuse? Internal Switch Mode Power Supply Faulty. Unless your a technician you'll need to take it to one or an Apple Centre if under warranty.

Sometime the cross-talk of signals is caused by the wiring behind the computer, touching. Separate the wiring.

Try clear epoxy glue. It will come in two tubes that you mix together. You will need to have a way to hold the parts in place until it reaches full strength ~ 24 hrs. Available at Harbor Freight online or HF stores.

Hi, Please check it monitor color adjust button. If ok then you check it monitor cable if change possible then change it or power cable also proper connect. If not solved contact Good Monitor technician. Thanks.

Power supply failure

No solution available? This is a short circuit problem, can only be solved by repair

You can buy a "can of compressed air" in most computer and retail stores. This would be a better option then disassembling the monitor.

Change display settings in energy management to NOT turn off when closing the laptop

yes you need to.

Please download the service manual its available online. it will guide you to reset it back in position.

The only way to test is to use a known working power supply or known working cinema display with the parts you already have.

the best sway to deal with apple products is to bring it to apple themselves......9 out of 10 times they will fix it for nothing

Here's something to get you started. I've honestly never heard of that website though, so buyer beware.
