most probably the lamp ballast is defective ,you need a new one

Hi, it is the problem with the Planar (motherboard).

this is a common problem with the capacitor, try opening your monitor and see if there is a capacitor swalow like gonna blow... the capacitor has a form like a AA battery... if changing the capacitor the problem persist maybe is a problem with the board and you need to search if the board have continous power....

If the adapter goes out its most likely the adapter. Check the voltage on the adapter and try and match one up on the internet as the one you order from the company will most likely cost 10x more. You need to know the output voltage and amps.

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!

Hi...there
Sure, you can fixed by replaced the backlight inverter or repaired it.

I have a red tint on the left side of my display at all times. also red smear after any white boxes in display. Has anyone else had this problem?

Are you sure it's the backlight? Many Planar LCD monitors have issues with the capacitors on their power supply boards. The symptoms include a power light and no picture, or just a flash of a picture when powering up and then nothing.

The fix for some of these problems is about $8 on 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 (3/4 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 if the failure looks like I described. I've fixed several of these monitors so far. All the problems were related to the power supplies. Same with the Planar PL1700 LCD monitors.

Yeah, only mine was a blue line. this is usually caused by a faulty capacitor. The only simple way of fixing this, is to replace the monitor, or try a different, one and see if it still occurs. If it does, then try a different, Cable. if this still does not fix it, then you are looking at an internal problem with the video hardware.
