Question about Planar PL2010M 20" Flat Panel LCD Monitor

Bad power board Planar PL2010M

Testing on the power board shows voltage starts at 12.25 and quickly drops off as if a capacitor is discharging, until it reaches about .4v then slowly re-charges to about 12.25 and drops off quickly again. I can't even get the power LED to come on. Do you know where I can get a replacement power board?

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!

"Bad power board Planar PL2010M"

I opened up my Planar PL2010M and the capacitor's 1,3,4 do not look the same as the part numbers you listed (P10275-ND)etc look on Digi-Key's web site.

The part number you give are in capacitor slots 22,40,60,54,,52,55,56,57

Any ideas on what I am doing different my monitor part number is 997-2827-00

He is right... I got one for (almost free) by replacing a few caps on the power board after someone else gave up on it. In this case it was easy because the caps in question were visibly swollen and thus easy to spot. Local electronics store had the replacements for maybe a couple of bucks.

I have a GE microwave oven model J VM131K002. It came with the house and may be twenty years old (I have been here 11 years)


read carefully with common sense:
can take some time. This is where you must be able to read a wiring diagram and do some "live" checks on parts. First easy check is to make sure power is coming off your control board at the MW relay. Make sure of the wires and test here, if you have 120 volts at this point, you have ruled out a lot of parts that could be the problem. You have now ruled out any switch problems, control board problems, or a thermostat or 2.If you do not have power from that MW relay on the control board, you must trace the wiring back to see if the proper voltage is going through your switches, any thermostats, and arriving at your control board. Your wiring diagram on your sheet will show you where and what to test. Below is a general switch test troubleshooting guide.

mwswitchtest.jpg mwswitchtest2.jpg If the proper voltage is coming into your control board and you are not getting voltage at the MW relay, then you need to replace the control board. If voltage is interupted by a thermostat or switch from your testing to the control board, then replace that part.Now, testing from the MW relay on to your transformer, high voltage capacitor, magnetron, and diode. Do not do any voltage reading from the secondary side of the transformer on, this can be a deadly microwave oven repair if you do not follow directions. This can result in electrocution and the "blowing-up" of your voltmeter, only do OHM testing with the power off and the capacitor discharged. Someplace in this circuit, usually before the transformer, you will have another thermostat to test. It is usually mounted on the magnetron. Do a quick OHM test to see if it is open or closed.
Now to test either the transformer, high voltage capicitor, magnetron, and diode, you must test each part separately. A good rule of thumb, if your capacitor is bad, change the diode also. Another note, if you are working on an OTR model and you have determined to be one of these "heating" circuit parts, you can not test these parts until you take the unit down. If you don't have the parts with you and you have to order them, order the magnetron, capacitor and diode and you will have a 90% chance of solving the problem. If it is an older microwave, order the thermostat also, most times you can return un-used, un-opened parts. Check with your parts supplier. This way you only have to take the unit down once.

My Planar PD470 will not power on when I press the power button. Any suggestions???


Common failures are due to bad caps in the power supply, that will be the first place to check.

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?

Planar monitor goes black, what's the solution


Check the power supply first.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Pl2010m orange standby light, black screen


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.

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!

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).

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.

Replacement External Power Supply


So the old power supply doesn't have the output voltage, current and polarity noted on the label? What a ripoff! *grin* Did you look on the case near where it plugs into the monitor? Sometimes that will tell you the voltasge and polarity. Poliarity? Get that one wrong and the monitor could be cooked instantly! But it's usually positive. I found a completed eBay listing that had this info: "the power supply which the seller used to power up this Planar Flat Panel is inventoried as follows: ViewSonic 12V Power Adaptor Model # SYS1126-5012" I looked that one up, and it's listed as 12V at 4.17A. PC Hub has them for $28.62: http://www.pchub.com/uph/laptop/345-19804-2285/AC_Power_Adapter_5V-12V_Others_SYS1126-5012.html Good luck!
