This may be related to a power supply problem that these monitor have. I think you need to fix the power supply board inside the display itself. It's giving the logic board and backlights fluctuating power and they have weird / intermittant problems.
There is a supplier of power boards online, you can google them with numbers from the board but I don't suggest using them. Look for information on the company before you buy from them. I've seen a lot of complaints for this "international" company.


First check that you are getting a strong 12V from the external power adapter. If so, the problems may be as simple as changing out a few capacitors. (about $8 in new capacitors, plus shipping)

On the PL2010M monitors you need the following parts. I've added digikey part numbers to make life easier:

P10271-ND 220UF 25V Capacitor (3 or 4 depending on PS)
P10275-ND 470UF 25V Capacitor (1)
P10221-ND 470UF 10V Capacitor (4)

If you're not comfortable with soldering and de-soldering electronics, take it to a local technician for the work and give them the parts list above. That should work to fix your issues. I've fixed several of these monitors so far. All the problems were related to the power supplies having bad capacitors. Same with the Planar PL1700 LCD monitors.
There is also a single capacitor on the display logic board, but I haven't seen this one go bad yet.
Good luck!

Auto adjustment locked and picture is fliker


Its not auto adjusting because of the flickering. Its flickering because the screen itself is losing voltage so it cant stay on. You can try hooking up the monitor to another computer just to rule out a bad video card but it looks like replacing the LCD is the only solution.

Display problem


the adjustment box for colour, brightness and contrast stays fixed on the screen. i tried pressing the exit button.... after a few times it disappears only to reappear within a few minutes. also the auto adjustment option, for which we are supposed to manually press the i button, keeps auto adjusting the screen whenever it feels like it. the box appears right in middle of the screen and is a real nuisance as it blocks out the main portion.

Hi,
In case you have connected both the DVI and VGA cables to the back monitor can cause this problem. Try unplugging one of the cables and check if the problem gets resolved
