I have a Hitachi 55HDS69 Plasma TV. Can the Hitachi JP50761 (JA06715) Main Digital Board, cause the following problems: 1.Dark video 2.When I pull up the volume bar, it shows three volume bars, instead of 1. Does the Main Digital Board being defective cause the issues I am having or are these issues normally caused by another part in the TV.
Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
