Updated PMCv2 Installation and Operation Instructions (for purchases on or after 25 April 2015)

…because you want your Panasonic Plasma TV to look as best as possible! Your Panasonic Plasma TV may still be the centerpiece to your entertainment system, or it may have been moved to another location (master bedroom, game room, guest room, etc). Regardless of where it is, you want it to look its best. The PMCv2 will help you reach that goal.

Over time, all Plasma televisions adjust their black level. However, certain Panasonic Plasma televisions adjust their black level incorrectly. It is a factory design flaw that has been repeatedly tested and confirmed, and finally a solution has been found. The PMCv2 bundles up that solution into a neat, clean, tiny package that plugs into the back of your TV. Simply plug it in, and enjoy. “Plug and Play” at its best.

The Black Level of a display device (be it TV, Projector, Monitor, etc) is the blackest black that can be displayed. It is the minimum luminance (or brightness) that can be displayed on screen. In other words, how dark a dark, night-time scene in a movie can actually get, when viewing it on your display. This absolute darkest dark is the display’s MLL, or Black Level.

Every time your TV is powered on, the PMCv2 will ask the TV how old it thinks it is. If the TV thinks that it has been used for more than 150 hours (total), then the PMCv2 will simply reset that value back to zero (0) hours.  All you need to do at that point is turn the TV off and back on again, and the TV will now think, “Hey, I’m brand new!” and your black levels will be at the deepest possible (for that unit).

The back of your TV has a service access cover.  On some models it is a hard plastic rectangle that snaps into place.  On other models, it is an adhesive sticker.  Below is an example of just one model..

Remove the access cover and you should find one of the connectors shown below.  Plug the PMCv2 into whichever of these two connectors you have on your TV.  PMCv2 units ship with BOTH connectors for 2008-2009 and 2010 model year TV’s.

2008-2009 Model Year Panasonic Plasmas:

2010 Model Year Panasonic Plasmas:

Some examples with the service connector area circled:

Some examples of submitted customer installations:

The PMCv2 will reset the black level on your TV approximately every 150 hours of TV usage.  Assuming the TV is on for three (3) hours per day, it will reset roughly once every seven (7) weeks.  If the TV is on for seven (7) hours per day, it will reset roughly once every three (3) weeks.

The PMCv2 has been designed to “plug and play,” with maximum convenience in mind.  That means that you plug it in once and forget about it!  You can, of course, remove the PMCv2 at any time.  Once it is removed however, no more resets will occur (until it is re-installed) and your TV will once again begin to experience Black Level Rise.  You may unplug it re-install it as often as you see fit, but that kind of defeats the convenience factor, doesn’t it?

If the LEDs on your PMCv2 are too bright for your liking, you can instruct the PMCv2 to turn them off by moving switch #1 (the switch closest to the protective heat shrink sleeve) towards the “LED OFF” label using tweezers, a toothpick, etc. In this condition, the LEDs will turn off after about four (4) seconds. To ensure that important PMCv2 activity is not missed, blinking LEDs are not affected by the LED OFF switch (see “LED Blinking Patterns” section for more information). Additionally, even in the LED OFF condition, every time the TV is turned OFF, one of the LEDs will re-illuminate (red or green, depending on the mode switch) for about four (4) seconds to remind you that the PMCv2 is installed and operating properly, and then turn back off again.

• The PMCv2 LED (green or red) stays on (not blinking)
  If either LED is solidly lit (or stays on for four (4) seconds then turns off because switch #1 is set to “LED OFF”) that means the PMCv2 is operating normally, waiting to again check the TV the next time it is turned on.
• The TV’s front LED is on, no image appears on the TV, and the PMCv2 green LED blinks once every few seconds
  Congratulations! The PMCv2 has just successfully reset your TV’s black level! Simply turn the TV off and back on again. This is normal and will happen again every 150 hours of TV usage to ensure that your TV’s black level remains at its best.
• The PMCv2 green LED blinks twice every few seconds
  The PMCv2 has just attempted to reset the TV’s black level but something went wrong and the value was not properly stored in the TV. Try turning the TV off and back on again to let the PMCv2 try again. If this condition continues to occur, then the PMCv2 is not compatible with your TV and you should flip the switches on the PMCv2 towards the UND label and turn your TV off and back on one more time. This will instruct the PMCv2 to restore the original values back to your TV and the PMCv2 will then go forever dormant.
• The PMCv2 red LED blinks once every few seconds
  The PMCv2 has just successfully restored the TV back to its original condition (e.g. like it was before the PMCv2 was installed), and the PMCv2 will no longer attempt to reset your TV’s black level. The PMCv2 may be left installed (it is now dormant), or removed / discarded.
• The PMCv2 red LED blinks twice every few seconds
  The PMCv2 has attempted to restore the TV back to its original condition (e.g. like it was before the PMCv2 was installed), but the value was not properly accepted by the TV. Try turning the TV off and back on to give the PMCv2 another chance to restore the TV back to its original condition. You may additionally try removing the PMCv2 completely. If your TV functions normally with the PMCv2 removed, then you may simply discard it.
• The TV’s front LED blinks and no image appears on the TV
  The PMCv2 is not compatible with your TV and you should flip the switches on the PMCv2 towards “UND” (Undo) and turn your TV off and back on one more time. This will instruct the PMCv2 to restore the original values back to your TV and the PMCv2 will then go forever dormant and not bother you again. At that point you may leave it installed or remove it from your TV. (NOTE: If pushing the TV power button does not work, try holding the TV power button for at least five (5) seconds and then release it. The TV should “click” off and then try to turn back on automatically.)

No Way! The PMCv2 only resets how old the TV thinks it is. The PMCv2 does not reset any of your contrast/sharpness/tint/etc settings, nor does it reset your channel list. The PMCv2 does not touch any settings except for how many hours the TV thinks it has been used.

Of course not!  The “service menu” and “service connector” are two very different things.  The on-screen service menu (accessible by several button combinations while the TV is on) does contain an hours counter and a cycles counter (how many times the TV has been turned on), however neither of these counters affect MLL/Black Level.  The counters that affect MLL/Black level are on a different area of the TV and are not accessible through the on-screen service menu.

There is no need to reset the counters in the on-screen service menu, as it has been proven to be ineffective at reducing MLL/Black Level.  I rather suggest you leave it alone and it will continue to give an accurate indication of the ‘true’ age of the TV, while the PMCv2 is quietly maintaining your inky blacks behind-the-scenes.

If for some reason you are unsatisfied with the PMCv2, then you can flip the operational switch from “RUN” to “UND” (short for Undo).  The next time the TV turns on the PMCv2 will restore the values in your TV to their last known-good values before the PMCv2 did its magic the first time.  The PMCv2 will then forevermore just lazily sleep and not bother you ever again.  You may leave it installed or remove it from the back of your TV and curse at it, throw it away, run it over with your car, give it away with stale Halloween candy, sell it and recover your investment, hack it and make it finally do something useful, or any number of other alternatives.

Your PMCv2 has been fully tested before shipping. If you believe that your device was damaged in shipping, please contact me for a replacement. Aside from shipping damage, there is no other warranty offered for the PMCv2. You assume all risk and liability for the use of the PMCv2. I have spent a great deal of effort to reduce the likelihood that the PMCv2 will cause harm, but I cannot and will not assume any liability for any damage caused by its use or misuse.

That is a very good question.  All I can do is give some of my background and let you make a decision.  I have updated the About Me page for just this very reason to include more biographical information.. I worked very hard for over twelve (12) months to produce a quality product that is both reliable and inexpensive.  At the end of the day, it is your choice to make. Hopefully the PMCv1/v2 Feedback Page is filled with enough feedback from existing customers to show my reputation as both an engineer and a businessman.

You can! AVS Forum user mironto has created a fantastic DIY page that uses an Arduino processor and some software to perform the same reset that the PCMv1/v2 performs. In fact, mironto’s DIY page is what inspired me to create the PMCv1/v2 for those who wanted access to the solution without all the “do it yourself” hassle. Check out mironto’s DIY page for more information.

Actually, a lot. Tons of thanks and credit is due to my wife for putting up with many late nights working on this project. An abbreviated timeline of the Panasonic Black Level (MLL) problem and major milestones towards a solution (including mironto’s DIY page and audiodane’s PMCv1/v2) can be found on the PMCv1/v2 History page.
