I have a three year old Panasonic 32" CRT TV.  Does it exist a way to
have it start up in AV input mode and not in tuner mode?
I haven't seen anything in the config menus...
Thanks for tips and comments

Our lcd computer monitor is causing alot of static on some am radio
stations.
Was wondering what type of capacitor to use to filter?
Thanks.

I'm looking for mains 0.1 - 150A range current sensors with some kind of
computer interface:  1-wire, RS232/485 / Ethernet etc...
Induction (transformer) or Hall type, one or three phase.
Not high accuracy, 5% would be ok.  Hopefully not too expensive ;-)

I have a Kenwood VR-407 which keeps going into protection.  The ±12VDC
supplies are unbalanced.  The schematic for the circuit is posted in
a.b.s.  It's just a basic circuit, it uses a center tapped transformer
feeding into a full-wave bridge, with the center tap grounded, with a

I have a Sharp Camcorder model vl-ah50 that won't power up. Is there
some way to manually eject the tape? Thanks!

I'm repairing my flatbed scanner but I can't figure out what the output pin of
the 7905 connects to.

Does anyone have any data on electric fence controllers? I'm trying to fix
one that uses a 6V battery for power.

Replaced it with hvr 6x2 diode however once again it and fuse burned
though "high voltage rectifier" diode hvr1x stayed ok

Does anyone know the date codes that Mallory uses on their electrolytic
caps a 1900ufd at 450v?  Here's a couple of lines..

After 4 years of bulletproof service, my Canon digital camera has gone

I will be upgrading my mother-in-law's (the Big Kahunah) TV in a
couple of weeks.  Part of the deal is that she is switching from cable
(Charter) to FIOS (Verizon).
Is FIOS from the outside box to internal TVs the same old RG6 and F

Dirt cheap but 1 scart only but an almost punch-out in the case for a second
scart for other models. To use on TV and a recorder. Easy to get in the case
and cut out hole and mount a second scart. Can you just straight parallel
jumper across the video and sound and ground lines ...

I need the following parts for a Mits. HS-U410 VCR.  All these parts
are NLA from Mitsubishi, and this model is probably too new (1996) for
any aftermarket parts to have been made for it.  If anyone has any of
these parts laying around, I'd be glad to take them off your hands.

I'm trying to replace the defrost heater in a Whirlpool fridge/freezer.
The calrod heater delivered yesterday has no connectors on the wire
leads, and I don't know where to get them or what to call them.
Description -- These crimp-on connectors are similar to the familiar

I just managed to get hold of unbuilt Heathkit alarm clock GC-1107.
The electrolytics were dry and the speaker is shot.
Finding replacement caps was easy, but does anyone here know the impedance
of this 2,5" speaker?
