Acer LCD AL 1706 A will not come on but the power light blinks.The cables were loose several days ago, I tightened them and it worked fine until just now. Rechecked the connections, plugged in a different monitor and that worked. It was mfg Jul 2006, worth repairing?
The problem can be bad capacitors in the power supply, look for bad caps with bulging tops or seal, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

If your monitor shows a yellow light and it won't turn green, the problem most likely lies with the computer. If your computer is not sending a signal to the monitor, then you have a computer problem. One way to test this is to turn the monitor off and the computer off, too. Turn the monitor on and if it is working, it should display a message telling you that there is no signal. If you see that message, you can assume the monitor is working. If you do see it, now turn on the computer and see if the message changes. If you turn the monitor on and you get no message, you can assume the problem lies with the monitor itself. If you have access to another monitor, hook that one up to test the computer output.
You can now either get the monitor fixed or the computer fixed, depending on which one is bad.
It seems that you have a failing backlight lamp or inverter board, these components are inside monitor, you should take it to an Acer service center, don't forget to check if you have a valid warranty, in this way you can save some money.
This type of problems are commonly seen with the monitors and this generally happens due to a faulty display cable (vga Cable) or the connecting port or monitor driver (driver 10% only). Cable should not be tensed it should be comfortably plugged in. please connect both power and display cable properly. Also try replacing the cable at shop. just go on shop and check with a new cable. if this fixes the problem then get a new cable. otherwise this could be problem with internal display cable or something else internally wrong, which requires a technician.
Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.
i have experienced the same problem (power cycles on and off and on and off... nothing but Acer logo and black screen) on 2 Acer model 1706 A version 1706 Ab monitors both built in July 2006. Before the customer reported the 2nd monitor with the same problem, i sent the 1st one into Acer for warranty service (after testing in on 4 machines w/4 different video cards). They shipped it back with a paper saying the monitor was repaired. I returned the monitor to the customer and it exhibited the same symptoms (aka, not repaired). Could there have been a bad batch in July 2006? When I plug a new Acer AL1716 monitor into the same computers, I have no problems at all.
sounds like a slightly damaged power supply. try powering up with an equivalent supply. if only an ac wall cord is plugged in for power, then internal supply is at fault
