Question about Acer AL1715 17" LCD Monitor
It comes on and shows the picture but then turns off and comes back on and shows the picture and turns off again repeatedly. It seems to keep doing this forever. It is getting power and is connected to the computer or it wouldn't show the picture. Hi all! I have a Acer LCD AL1715 Monitor and it is repeatly flashing on and off and making a clicking sound. I can see the Acer splash screen when it turns on for that second. It wont even power off it just keep flashing on and off. I had to unplug the power cable to get it to stop. Is there hope or is my monitor going to end up in the place where electronics retire? Thanks in advance
I have been repairing LCD monitors for several years now. i work as a technician in a steel plant and we have hundreds of these in service. What i am finding is that it doesn't Matter what brand it is or what model. If the Screen is flashing on/off/on/off/on/off most likely 98% of my repairs anyway are Capacitors on the powersupply board. when you get it open look to see if any of the Caps have the tops or sides bulging this makes it easy. If you dont see them bulging out then what you need to look for are pairs of caps close together & almost always near the mosfets/transistors mounted on a heatsink find the pair with the lowest microfarad rating and replace those first if possible replace with a higher voltage rating as i am finding most manufactures are using to close a tolerance and this is whats causing the issue in the first place.
I hope this helps.

Does sound like a power supply issue... they are fixable but it's somewhat involved.
