v-com (vcom) value for Panasonic LCD/LED TV in service mode

The meaing of the v-com (vcom) value for Panasonic LCD/LED TV under the service mode.

Wonder why the LED TV screen flicking like crazy and look washed out in white noise? Particularly when you enter the service mode for the first time?

With a wrong v-com value, the TV screen will look washed out with continue flickering.

When the vcom value was wrong, you cannot even see the service menu text clearly. The screen just flick like crazy. When you getting close to the correct value of the vcom, the text on the service menu will became clearer and clearer with a relatively steady background.

In one case, a vcom value around 0x60 gives better result.
