CTL 170Lx repair

SYMPTOM: 
NO PICTURE,
FLASHING LED (AMBER & GREEN),
FRUSTRATED USER,
BROKEN LCD DUE TO FRUSTRATED USER


PROBLEM:
I spent hours and hours troubleshooting the electronics on about 6 of these monitors which were brought in for repair. I just couldn't figure out what the heck was wrong with them. And I eventually just attributed it to UNKNOWN and NOT WORTH MESSING W/ ANY LONGER, two commonly used "solutions" here lately. Yes, I've been struck with the equivalent of writers block. The last 3-4 weeks it seems that I can barely get anything done. At first I just said to myself, "NO MATTER HOW GOOD YOU THINK YOU ARE, YOU"LL NEVER BE ABLE TO FIX EVERYTHING." And that led to "WHAT THE HELL IS WRONG WITH YOU, YOU CAN"T FIX ANYTHING." But today I'm turning it all around. I rediscovered a good source of information that I once heavily relied on:

www.GOOGLE.com

After revisiting these again, and asking my friend GOOGLE, I was able to come up the following solution....

	Monitor Reset Guide

If you have a monitor that is blinking Amber and Green that means the monitor needs to be reset. This usually happens when the monitor goes into a failsafe mode to prevent damage when there is a power spike or power drop from its power source.

Only for the 190/170lx and 201LX. For the 171Lx, 191lx, 195uw and 220uw, see instructions at bottom of page.

To reset the 170/190lx monitor first unplug the power from the back of the monitor.

Then you will want to hold down the middle button and the button to the left of the
Middle: O-X-X-O-O

While holding those buttons down plug the power back into the monitor.

The light will flash green to amber and after the third flash you let go of the buttons
Green amber, green amber, green amber, let go.

The light should then stay on and be steady (either solid amber or solid green). The display will come back if it is connected to a computer. The computer may need to be reset to re-sync with the display.

You may need to try this a few times before the reset will work.

You also may need to unplug the VGA/DVI cord from the back of the monitor, some monitors can only be reset when they are not attached to a computer.

Also, rarely, some monitors need you to hold down the reset buttons until the Energy Star symbol appears and the light stays solid.

171Lx / 191Lx 195uw 220uw Procedure:

The reset procedure is the same as the 170lx/190lx except you press down different buttons to perform the reset.

You need to press and hold the buttons on either side of the center power button: O-X-O-X-O

The rest of the reset procedure is the same.
