Hello, I have a monitor problem!


My Specs first:


i7 3970 x

Sabertooth x79

Nvidia GTX  690 

32 gig corsair Dominator RAM

Windows 7 professional


Monitor issue and the problem solving steps I've taken are as follows.



I have 3 x 27 inch ACER LED monitors,  Model number S271HL. I use a high quality DVID cable for all three monitors.  All three worked great for a long time, and two still do.  Currently, Two monitor power buttons turn blue when on, auburn while in sleep mode, and off when powered off.  This is normal.


Problem: The monitor in question, has problems starting after the power has cycled on and off.  The power button on this monitor stays auburn when the display is working. It does not turn blue at all, anymore.  It only turns auburn or off.


When I turn the computer off, that monitor stays on, and the screen starts to cycle through Green, White, Blue and Red screens.  If I pull the power cord from the monitor and plug it back in, when I am ready to turn my machine back on, the monitor flashes the auburn color on the power button. 


When the power button is flashing, My computer can see three monitors, but the display of the monitor in question, stays black or off even though it is giving a signal to the machine.


The flash will slowly get longer and stronger until the monitor comes back to life... Light tuns solid, monitor comes back on.


Note:  I can sometimes turn the power light off while it is on a long flash, and if I wait a minute, the power will come right on.(That is only if the flashes are getting stronger)  Also, sometimes I can plug the DVID cable in and the connection bumps the power switch solid, It may just be a timing coincidence.  My power button on that monitor has been flashing for two days now.  It is getting stronger, but very slowly.


I have plugged in the DVID cables into the other monitors, and switched ports to problem solve. Cables and ports are not the problem.  I have tested and the other monitors work in all ports and with any cable.


  Thanks for your help!

I don't know if this is a hard fix, but I will tell you what I did.  My monitor power button went solid orange, and finally powered itself on.  When it was on, I went into the monitor settings, and put everything back to default settings.  My power button is now blue again, and my monitor powered on with no issue.  I hope that was the issue.


Fingers crossed!

I have the same issue with both of my s271hl monitors. Please Help! I picked these up at SAVERS for $7.99 each so i can experiment on one of them if you want.


One of mine will work for a bit then go back to on and off. Also, it will flicker the blue light sometimes. Is Energy save mode messing it up? IDK

Numerous kinds of faults such as these are caused by electrolytic capacitors failing in monitors, and someone able to solder in replacements can often have success sorting them out. The site below wasn't dealing with exactly the same symptom, but shows what needs to be done:




Another possibility where the monitor is powered by an external power brick, is they can also have capacitor problems. If you have two with different behavior, swap the power bricks and see if the problem moves, or stays in the same monitor.

The images on the page Platypus references are excellent.  I've been down this road, but not for a monitor, but a plasma TV.


There are two small things I didn't see mentioned as I scanned through that page.  One is that most electrolytic capacitors these days are going to be in a "can" type enclosure and if you look at the end opposite where the leads are soldered they quite commonly have three channels in the top that are positioned like the arms in the Mercedes logo.  That's the type of capacitor that's used most often and many are shown in the images there.  There are other styles, though.


One telltale sign that you've got a capacitor going bad, if not already blown, is that a slight dome will form on the top of the "can" where these channels are located.  If you see a capacitor that looks "fat" in any way it definitely needs to go.


One of the best online sources for electronic components like this at rock bottom prices is Futurlec.com.  (I have no financial interest or connection whatsoever, I've just used them on multiple occasions because their pricing is so good).  See their capacitors page for photo examples of electrolytic capacitors plus most of the other common types.
