Thanks Ian, that's great. Will start work on it this weekend, and will let you know how I get on. Many, many thanks for your excellent, generous support. Ian

Many thanks for that Ian. Yes, it would appear that one of the through-holes has corroded badly, so that one of the pads popped off attached to the battery pin, even though I used proper de-soldering kit. Is it a multilayer board or just double-sided? Thanks.

I have stripped the dimmer down, and sure enough the battery has expired and leaked onto the board. I have de-soldered and need to clean up the muck left behind. The pcb tracks look ok superficially, but I need to clean up first before I can check. Any suggestions as to what to use for this cleaning job, so as not to damage the pcb or tracks? Also, if the RAM has reset then is there any way I can get a new chip for this box? Many thanks. Ian

Many thanks for this guys, I appreciate it. Will let you know how I get on. Cheers

Hi there, I have an ID1216 (3-phase input) dimmer that has not been used for some time. I tested it today for a gig, but it failed with an error message that the Triac cards could not be detected, and a message that the fan was set to 'On' (it was running) when the unit was running cold. Set the dimmer levels to the 50% and 90% levels with the menu on a few channels but nothing happening. Any ideas? (though I suspect it will not be a quick fix!) Many thanks in advance, Ian
