Question about Planar PL2010M 20" Flat Panel LCD Monitor
This is the same problem I've seen several times. Fix the power supply board inside the display itself. It's giving the logic board and backlights fluctuating power and they just can't keep up.
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 also. I've seen a lot of complaints for this "international" company.
The fix for most of the problems on these monitors is about $8 on new capacitors (Plus shipping).
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.
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 technitian 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.
