I've had one of these sets (fantastic BTW) rigged up in our bedroom for the past couple of years and its recently developed a problem. Its become extremely hard to turn on, sometimes throwing up the occassional gibberish but usually kicks straight into standby and then refuses to accept commands from the remote or the facia. I can eventually get it going and from then on the picture is its usual excellent self but it still sometimes refuses commands. i remember there being a control circuit issue with these on original release but was assured the problem had been fixed. Any ideas? Any good engineers recommendable in the Thurrock, Essex area or thereabouts?
