Is can the c707 be changed easily with the board still in the tv? The C707 in mine has a burn mark through it and I have the replacement. It looks tricky to get in there with a soldering iron and replace. Should the board be removed or can it be done without removing the board? I am also confused as to the discharging of the residual power. It has been unplugged for a couple of days, but I did not understand the diagram on the front cover to discharge the system. Any advice? Thanks!!!
