Years ago I used to have some long tubes for getting spray cleaners into
difficult areas.  They were 24" long and I believe we got them from Caig,

I have a Sharp 32U-S60 TV that is nearly new (35 days), and I've
finally figured out what bugs me about it.  The Image is too big, and

have no schematic but I did look up the NTE equivilent for the TA1268N

Has anyone got specifications or part numbers for the drive belt and
speed control belt?

I got a slimline CDRW drive from Ricoh that doesn't show a sign of live.
Someone must have removed a blown fuse and soldered a bridge across the

I have an older Fisher "Studio-Standard" TV set (digital) which will not
