MY LCD PLANAR MONITOR PL2010M, 20.1", IS GONE BLANK

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?

Sorry, but this sounds like a controller issue. Are you able to open the monitor's menu? If yes, try the monitor on another computer with other cables, if that doesn't help its a internal problem. The only thing you could try yourself is opening it up and reseat all of the cables. If that doesn't help, you should contact a professional or consider replacing the unit.

To find out, I would browse through the on-screen menu using buttons on the monitor to find an option "Reset to default" or "Factory Settings" or something to that effect.

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!

A Chip on the monitor circut board must be reflashed. You need to send back to Planar, do an rma. They were very responive to me, sent me a replacement.

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.

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.

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!
