Got this nice professional twin cd player into my shop, a Pioneer
CMX-3000.
Customer claims "left player doesn't play cd's".
I tried some cd's and got the message E-8301 in the display.

I have a sony car CD shuttle that doesn't read any CD in the first three
trays.
If you put CD into any of the first 3 trays, it does not play, but plays in
the other 7 trays.

I have 3 perfectly good STK7216 voltage regulators, left over from a
long drawn out VCR repair long ago. I have no idea whether these are
still in any demand any more, but if they are I'd like to get rid of
them and turn them into cash.

Old FM radios never die, they just fade away...
I have owned and used quite a number of ordinary table top (or
portable) radios in my life. All of them tend to go bad in the same

 Got this set in the other day, model CS-28EX1C. This is a 26" set from
'93. It came in dead, and once I got it going (replaced the STR regulator)

I have this small TV on my kitchen table and watch it everyday to catch the news
while I munch down my breakfast. It is about 10 years old but it functions well
with that built in antenna. However, it intermittently loses ...

Hi, I just got a Panasonic 27-inch TV (model CT27G31U) and it's been
shutting off every few minutes for some reason. It's happening at
different invervals (sometimes goes out after 5 minutes, sometimes
stays on for 20 minutes before going out). When it comes back on the

Desperately seeking a 2SC2527 transistor to repair my scope. I live in
the UK and no one here wants to sell me one (or has even got one!!!!).
There seem to be plenty in the states but when you find the shipping
charges they make to cost uneconomic, so my question is does anyone

I closed my doors recently. I still have some office and workshop fixtures
and fittings left in my
storage unit, these are going free if you are willing to collect from the
Cleveland area of the United Kingdom. The lists is as follows:

Orion VHS player model VP-0040, ~1995 mfg.
I have the above VHS player, that will occasionally jam when
unloading the tape. Fixed once, but came back 3 days later
with a tape stuck in it and the mech jammed again.  

NAD 7020e receiver just failed most strangely. If only one source is connected to the appropriate input (such as CD),
the signal can be heard on both channels at about 1/2 volume when tape monitor or video is selected. Tuner is also
audible regardless of which input is selected.

I have a Sony CDP-CE315 CD changer. The display doesn't work. Well, that's
not quite true; sometimes, once in a while, the display does work for about
5 minutes.
There are no buttons on the remote for disabling the display.

    My faithful oscillating fan has given up the ghost. I know I can
go buy a new one but I like tinkering and fixing things so I'm looking
for some help.

Hello, I have a problem with my surround sound reciever, Pioneer VSX-D411. It
keeps flashing "AMP ERROR". I have opened it up, but didnt see anything burnt
or broken. Then again, I dont really know what I'm looking for.
I have tried just unplugging for a long time, which did ...
