lcd monitor won't turn on

I have three of these Acer AL1916 LCD monitors and am still using two of them. The third one was in perfect working condition when I disconnected it a week ago and set it aside. Yesterday I plugged it in and noticed the power switch did nothing: no power light and no "no signal" message. The screen never lit up in any way. I tried hooking it up to a computer but that didn't work, either. I have not attempted any dismantling but something inside must have gone awry. Is there any use sending it to a shop for repair, or is it time to recycle it? Can you suggest any likely cause of the malfunction? Might it be something that I could fix, myself (I am experienced working inside desktop PC boxes)? Please advise. Thank you!

Re: lcd monitor won't turn on

Dear friend,

There are many reasons for this problem. The first comes to my mind is the lost connection of Power cables and that can be soldered easily. You can get it rectified in locals.
Please note : This model comes with 3 years warranty, Dont take any self decision to rectify it else you will loose warranty. Check acer service stations in locals.

Regards,
Atul

Re: lcd monitor won't turn on

Have a look at the monitors case, at the power cable and at the connections.
See if something seems damaged.

See if you can change the power cable of the monitor with the power cable of the PC unit.

If everything seems ok you just have to take the monitor to a specialized service.

Re: lcd monitor won't turn on

hi if atul is right and your lcd monitor is under warranty then claim for warranty dont do any repair if your unit is out of warranty then like youve said your into desktop repair im sure your hardware enthusiast and as technician first you look into your hardware maybe its just burnt fuse inside the lcd monitor look to other electronic parts and think like technician

if you find nothing and cant repair yourself dont be ashamed thats normal you cant know all thing bring the unit to authorized repair center for lcd monitors

post answer wish to solve your problem

happy repairing

Re: lcd monitor won't turn on

Thanks to all who replied to my post. The monitor power comes from a direct plug-in to the wall using a common power cord; there is no "power supply" externally. Clearly something inside the case, or maybe the switch, failed. Since it is out of warranty and Acer did not respond when I asked them about factory repair, I'll probably peek inside out of curiousity. Who knows...might get lucky!

Re: lcd monitor won't turn on

it sounds like either bad cabling to your computer (check the cables?) or the ribbon cable inside the LCD monitor has come unseated.

The unseated ribbon cable problem is more common if you recently moved the monitor or dropped it a bit. You can open the back of the LCD monitor (unplug it first of course) and check to make sure the signal ribbon is seated properly, this is a common problem.

peek inside out of curiosity and maybe you would get lucky you dont have to say this statement if your really is into hardware repair luck is not the word for repairing its the process of knowing what is the problem logically

i suggest you bring your lcd monitor to authorized service center

Re: lcd monitor won't turn on

Hi Friend,
Its sounds almost certainly like a power supply problem in the monitor. It's quite common for the back light power supply on those monitors to go bad. If you can even find one, you can probably replace it yourself.

Thanks,
James

Re: lcd monitor won't turn on

Once the monitor goes bad its too expensive to fix it. Either buy a new monitor or spend too much to fix it which is not worth it.
