Planar PL LCD Monitor Fix Print
Monday, 03 November 2008 13:22

Problem: PL series Planar LCD monitor has no image and the power LED is flashing green and amber.

Solution: The solution to this is to reset the LCD. There are 2 different model revisions and in order to reset the memory, please follow one of the two solutions below.  You will need to check your serial number to find the correct solution for your monitor.

If your monitor has a solid amber light or flashing green power light, this usually indicates there is no video signal going to it.



  

If the serial number begins with an A:

 

Depending on the revision of the monitor, one of the following 3 methods should reset it to a normal state.  This reset generally requires both hands and possibily another person.

  1. Remove the power cable from the back of the monitor.  Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 3 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in. Keep holding the buttons until the green light is solid and the let go quickly.
  2. Remove the power cable from the back of the monitor.  Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 3 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in. As soon as you plug the power back into the monitor, release the buttons at the same time.
  3. Remove the power cable from the back of the monitor.  Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 3 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in. Keep holding the buttons for 5 seconds after the power has been plugged in and then let go.


If the serial number begins with a B:

I also had to remove the video cable from my Planar. Only then did the procedure work. You will know it worked if the monitor diplays "No Signal" message when finished.

Helpful Hint: Use a power strip, then you just have to turn the power strip on/off. As noted, VGA cable with signal cannot be attached. Rock on.

I just completed this on a Serial # B model. It worked with the VGA cable plugged in, but man, in 20 years I have never seen a crappier monitor than a Planar.

Well...I've know about this reset with the CTL monitors, but in attempting to do the reset on this Planer...it ain't happening. Tried all 3 solutions, both with video cable disconnected, and with it connected, still get the toggling amber and blue. Any other info, possibly capacitors to be replaced?

Thanks!

I had to leave monitor cable and power disconnected for about 10 minutes before it reset. (I have type B monitor).

Geesh, all I did was turn off the pc and I left the monitor on. Who would have thought that would screw it up?

In my case (with a PL2010M) I needed to hold down keys 2 or 3 until the on screen menu appeared. I could then release the keys and the screen would be OK. After a while the on screen menu would disappear and everything was back to normal.

My serial number starts with B. I had to remove the video cable, hold down the indicated keys (2 & 4) and had to have the yellow color turn solid. I first waited for green to stay on, but the yellow stayed on for a little bit, and then it started blinking between green and yellow.

A power surge took out my monitor one time ago. I recalled this site and again my monitor was resurrected! I love to talk geek and when nerds share their wisdom I will pick at your brains all day! XO for teaching us the unknown intricate complexities of our stone aged technology.Who needs a new one when this one doesn't die..lol it just has dementia.
