My friend Steve, who is unable to post here for some reason has asked me to post the following for him. Obviously he'd be grateful for any ideas. I've already suggested a larger hammer. Having just dubbed from hard disc onto blank DVD and finalised the result, my Panasonic DMR-E100H went into 'Self Checking' mode and has absolutely refused to come out. The machine will not turn off and after being removed from the mains and then reconnected turns itself on and immediately goes back to 'Self Checking'. I've left the machine switched on for 24 hours in the 'Sel;f Checking' mode in the hope that it might work its way through checking the DVD and everything else, but it remains determinedly in the 'Self Checking' mode. The manual states that 'Self Check' means that 'the unit is carrying out its recovery process. Wait until the message disappearsd.' If only!
