The power supply on my brand new LCD display just went bang -- more of
a "pop" actually -- and now it doesn't work anymore.
Lucky for me it's external and the display is OK.
I'm worried by what could have caused it though, since it's brand new

RF-out and the line-out, I get a picture that is barely visible and very

The battery has died and I'd like to replace it with a wall wart DC source.

Last year I gave my grandson (at his request) a copier for his
birthday.  It was a Konica 1112 I found at a garage sale, and it
worked for awhile.  However, this year he has asked for a repair
manual for it.  I fully expect this to cost more than the copier, but
