Many thanks, I might well be in touch soon! Sounds relatively simply - I draw the line at soldering but doesn't seem to need it. Will try your suggested test tomorrow (want to get at least a few movies watched while its operational!) and if it doesn't come straight back on will go ahead with the PS replacement.

Good to know Mr Tech Guy is still going strong - think my G61R will be paying him a visit soon - 2nd time the unit's volume control has gone now frown.
