Question about Televison & Video
SOURCE: Vizio VF550M volume stuck at 100
The 2 suspects are possible but there is a way to find it..try to get the control board and remove the vol+ button on it..then back the controller then power it on again try to push vol- on remote or TV..if no help you have faulty main board..

These new plasmas are very sensitive to dust I had the same problem with mine I would press the volume and the channel would change or i would put it on one channel and it would go to component by itself I took it apart and blew it with a can of computer air and cleaned the buttons with alcohol and swabs works perfect now. hope this helps

Im having similar problem and with my limited knowledge of lcd tvs and the voltages ALL being good except the pwr on or sw on voltage from the main board to the power supply which tells it to switch everything on Im guessing that something is going wrong on the main board. In the condition where it freezes it (the power on V) which switches everything on i get varied voltages such as 2.5 or 3 or (the normal 5v) and then when nothing powers up (blank screen) i read 0v on pwr on voltage but all my other voltages are corect (24v to inverter, 12 v to main board, 5v, etc.) Im guessing from researching this is that there is in improper voltage somewhere in the main board circuit. I have been unable to find it so i may order another board and post back.
