This is really annoying me.
From time to time I get a dead-bulb warning on the mini display. It usually clears a few seconds later, but from time to time I've managed to stop while it's still active but have never found any of the bulbs to be out.
I've checked all the sockets, and all the connectors I can find, waggling them without provoking an error and then cleaning them anyway.
Finally, I've decided to disable the warning system - but does anyone know which pin on the lamp warning module is the output to the mini display?
