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.

Good luck!

Hi My Planar (PL2010M) suddenly went black. On restart, it flashes briefly but never comes on. Any suggestions?


I have a similar problem on my Planar PD470; power supply failed after about a year and a half. I heard that their HDTV power supplies had a higher than normal failure rate. I have someone working with the company to resolve, but I'm not optimistic... Bah Humbug. How long have you had your set?

Monitor will not start


Most common failures in Dell E153/152/172/173 are blown fuse, shorted transistors in the inverter circuits.
Please look at my albums to get some ideas.

Try booting the pc in safe mode (press f8 at startup). It may be possible that the pc is trying to send too high a resolution to the monitor...unlikely though. The symptom you describe usually indicates that the power board or the inverter board in the monitor are defective. If it does the same thing in safe mode, you have 2 options.

1. Replace the power board and inverter board (do the inverter board first.......it's the cheaper one (10-20 dollars).
2. Send the monitor back to the seller for a refund, or get a new monitor.

Sorry I couldn't give you more positive feedback. Hope this helps.

No Display on my Samsung 204B monitor


If you know how to open it up and get to the power supply you will find three capacitors 2-820uf and 1-330 @ 25vdc 105o.they will have puffed up tops replace them. FYI the monitor has a 3 year warranty.

Backlight replacement


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.

Monitor Black, Green Power Light Flashes Monitor is 4 yrs. old


Assuming you've already checked your driver and system settings, tried a different monitor, and checked the cable and connector pins, this would almost certainly be a problem with the power or signal circuit board inside the monitor.
