Of course they will. But this radio is old enough (I assume) that Sony

Businesses (in general) seem to be increasingly less worried about

In the UK it's common to get long warranties on quite low price things - a
3 year one on a 20 quid cordless drill. But they don't repair them if they
go wrong - just give you a like for like replacement or your money back.
Perhaps that's why such things cost about twice as much as in the US. ;-)

Or if you were happy with the features and sound quality, you can usually
find a used replacement unit for whole lot less at your local salvage yard
or by searching E-Bay.

Hi All,

A couple weeks ago my radio in my ford fiesta started to behave very
strangely.

I wonder what it could be. Is there any chance if I restart it somehow
it will work fine again or I just need to go to a ford service
company?


For all intents and purposes, car radios are disposable. It will almost
certainly cost you more to have it fixed (if it's fixable) than to replace
it.

Seriously, it's junk, go get a new one installed.

Or, like top-posting Bob notes, junkyards are sometimes good. Don't let
'em rip you off though. Ford radios ain't known for their sonic purity.
For many years Ford used the car's frame as the signal return ground from
the speakers... not a good idea if you know anything about RFI, but it
saved them the cost of 15 feet of 18ga wire, maybe $0.50 if that.
Times a few million vehicles.

It shouldn't be too difficult to locate battery operated wireless
speakers (the transmitter uses a wall-wart); I passed up some
rather substantial ones (solid heavy cases, features visually

were priced at $4.99.

It's usually the other 'way round -- products cost less (for whatever
reasons) in the States. I bought a nice name-brand 12V cordless drill for
$20 at Home Despot last Christmas. Hardly pro quality, but fine for light
home work.
 
The DC jack on the side of my Toshiba SD-P1600 has a small
barrel in its center, and that barrel has broken off, rendering
the machine unchargable and therefore unusable.
Don't make things worse by sneezing on the unit.

Have you contacted Toshiba?

I was thinking more along the line of purchasing a part. There's a good
chance it's a standard hermaphroditic power jack, and you might be able to
get a replacement from Newark, Allied, Mouser, etc.

I guess I'm the only person here who knows who Billy Gilbert was...

My Dick Smith Series II meter is giving me fits. Upon initial power up,
it works fine. Then it starts giving erroneous high ESR readings. When
this happens, I attempt to zero the meter. Instead, it shuts off, and
refuses to zero out.

After a few moments, it works fine again until the entire cycle starts
again.

I subbed a 9v battery for the included pack...mostly because I didn't
have any AAAs around when I first built it. The unit gets light use
around my hobby shop. The battery reads 9.05v open circuit, and pulls
down to 9.01v under load, so I don't believe it to be the fault
(although I included the info, just in case).

Anyone have similar issues?

Hello all, I am trying to replace this damaged component (attached photo).
I'm pretty sure it's a surface mount capacitor but I can't figure out what
it's values are or where to get a replacement (digikey?). Thanks to anyone
who can help!

Nathan
It is a surface mount electrolytic cap. The value could be either the top
figure, 100uF or the bottom one 10^8 pf which is also 100uF. The other
figure on there only makes much sense if it is the working voltage at 16v.
However, I have to say that most sm electros in a value of 100uF, are
usually rather less than 16v rated, if only because of restraints in
physical size. Just as a matter of interest, what do you believe to actually
be wrong with this cap ? I have mostly found them to be pretty stable and
reliable unless they actually leak onto the board. You should note that if
you check them with an ESR meter, you are likely to get readings which are
rather higher than you would get with a conventional leaded cap of the same
value / voltage rating. This is quite normal, and does not necessarily
indicate any fault with the component.

Don't know the 2420. Is there a special button for the test which is
activated by a misaligned box and/or faulty cable, connection, plug...,
telling that the test is needed? Or a misplaced (too long) screw kills a
cable, or a cable is squeezed...

So remove the box and check again.

I'm not sure which 3-digit number represents the value, but I hope this

For example, if the first number, 100, is the value:
Look it up on the first link I included, and it turns out to be 10pf, 2%.

I did find that, but as you said, don't know which one is the value. I
remember once seeing a website that could decode these but I can't
find it.

Since its obviously a SMD electrolytic, the value suggested elsewhere of 2pF
is monumentally silly!

Its hard to judge the size with no other reference so if it was the 108 at
the bottom indicating a one a zero followed by a multiplier of 8 zero's that
could be 1000uF, but it doesn't look that big so I'd go with the top number
"100" as 100uF and 16V.

If there's that much pickup on the box or downlead, there's something

To e-mail, change noise into sound.

Looking a bit deeper the main problem stations are on UHF Channel 33, Mux D
the highest frequency of the local (Rowridge) group.
Unless anyone knows how to push the problem into the totally junk and so
deleted shopping channels, looks like a new yagi and downlead.
A near neighbour has no problem with any freeview channel with a relatively
short Yaggi in his loft space.
The immediate neighbour, so yaggi only a couple of feet away and parallel,
uses a line powered headend amp which perhaps could be
radiating/interfering/coupling. Perhaps a different mounting position should
be considered also.

If you can ascertain the age of the aerial in certain areas, as has been
said, it may not be suitable for all the FreeView muxes - in the same way
as some weren't suitable for Ch5. It all depends on the frequencies used
locally. In the London area the muxes are within the existing grouping -
you'd need to look it up for Rowridge. There are probably some yagis
still in use from the early BBC2 days which were peaked for just the one
frequency.

Could be a wideband type.

position should be considered also.
A few feet can make a difference. But while you're up there you might as
well change it. If you're in a reasonable field strength area go for a log
beam. Nice smooth response and good DP. And use a decent satellite cable
rather than plain UHF. I like these people for such things - and their
strap chimney mounting is a delight to use.
