I recorded Montalbano (BBC4 Saturday 18th) and watching it last night the video kept dropping out. It was as if the HDMI stream stopped for a second. It then took the amp a few seconds to re-handshake with the screen. Happened about half a dozen times. Watched a couple of other recordings (Homeland and The Diamond Queen) with no problem.

Setup: Humax FoxSat (original model) - Denon AVR23120 amp - Panasonic plasma. All connections HDMI.

Never had a problem before.

Watched my recording from the 18th last night and had no problems at all. Hopefully this was a one-off for you.

Thanks. I think I've got to the bottom if it. My amp runs as master on one of those master/slave plug units with a trailing socket containing all my other A/V bits (except the always on Humax FreeSat) - i.e. nothing is switched on in stand-by mode until I switch the amp on. I think the master/slave unit had started to fail and temporarily dropped power to the TV, only a fraction of a second but enough to cause a HDMI handshake and loss of picture for 3 seconds.

I thought it was the Montalbano source material because when I re-ran one section the fault occurred at what I thought was the same place. It must just have been one of those unlucky coincidences.

Any a couple of days later I got a similar symptom watching something from DVD and, in that case, I could see my DVD player power off.

Master/slave unit replaced with a wireless remote control socket - gotta keep turning off all the stand-by stuff to save the planet.
