While finally screwing a double mains socket to the wall after a living room rebuild (and putting a socket behind my hifi gear) something shorted behind the socket and tripped the house power. I sorted the problem with the socket but since powering everything back on, the amp won't sync via HDMI with anything... Just comes up with "not support" on the amp's screen. If I plug the tv straight into Sky HD its fine. I do get sound via fibre through the amp. I love my amp So assuming the HDMI board is knackered in the amp is this realistically an economical repair? Considering this was my fault is this considered an "accident" in terms of house insurance? Any advice on fixing my problem would be appreciated.
