I have a dual deck Sony tape player. I put a tape in the other night
and it wouldnt play. When I tried to eject the tape, it felt like there
was resistance on the eject button.

I opened it up and looked at it. The ejector itself is somewhat stuck
but can be pushed very hard on the inside to eject the tape. Is there
anything I can do to fix this?

Audio cassette?

Thats correct.

Thats correct.
You know what, the tape wont play even If I get it in there. There is a
little white piece of plastic that is supposed to be mounted down and
clear of the ejecting mechanism. It is kind of floating around in there
preventing the ejecting of the tape but even more important is when a
tape is in there it seems life the heads dont want to move. A belt
maybe?

That is probably the write protect detector. I suspect the mechanism is out
of whack, but you may not have much luck looking to diagnose that over the
net.

It is very possibly a belt. Assuming that this model has indirectly operated
decks i.e. the head plate is cranked in and the take up drive is shifted
courtesy of a cam gear driven from one of the capstans, then it is quite
common for a slipping belt to only be able to drive the cam gear to the
first point it encounters any mechanical reistance. At this point, the eject
lever blocking bar will have shifted into place, preventing you from being
able to operate the eject button to re-open the door. You should be able to
see what is going on quite easily. If you see the capstans start to rotate,
and then come to a stop, try 'helping' with a finger.

However, one word of caution. Many later Sony decks use a flat main drive
belt of an odd size, which is critical for correct operation of the decks.
Sony do not supply these belts as as a spare part, only a complete deck, and
I have not been able to source the exact size here in the UK, but that
situation might be different elsewhere in the world.

So I may be better off with a new one or a call to a service center.

One place to try is a hydraulics supplier. They often have all sorts of odd
neoprene seals.

So, can you bend it down a few hundred megahertz into the amateur 10GHz
band? Without spending more than you would for a Gunnplexer?


Probably not if the tuning element is a DRO.

Bill
The DRO has a tuning slut above it. You might be able to tune off frequency by a
few MHz. The DRO puts out very little power <-30dBm might be a good idea to add
an amp from mini-circuit, smdi, rfmd or hittite microwave, you should be able to
get free samples from those companies. Another idea is to just get another puck
in place of the one in the cavity. free sample pucks are available at shf
microwave.

Also you might try trimming the cavity to give it more area thus decreasing the
frequency.

Sorry for my ignorance but I need some specific information.

I found several sites but still they are not explaining the things I do
not understand.

More over I need initiatives as a beginner in professional field.

Googling and reading books as a student while I was in my country,
Myanmar, I got a lot of knowledge background but whenever I met with
the real situation, I forgot everything!

I remember a certain experience of reading a book of Assembly
Programming for five months and Testing Practically with a computer and
facing with failures and problems before my graduation. When the
lecturer came and began his first lecture in Assembly program after my
five months of struggle, I found my first assemgly programm assembled
fine and ran on my computer.

That is why sometimes I asked silly questions in the forum.

All I need is a good initiative and some personnel gudience from those
who already have experience!

Regards

chassis no.? I think most Bush was Vestel (11AkXX).
I assume you have checked all the menus and tried different inputs to
eliminate the possibility of a setup error, and have the original
remote to check it with?
next step power supply or scan coils/ associated components. could be
bad eeprom.
see www.repairfaq.org for troubleshooting tips.

If none of that makes sense, then you shouldnt be poking arond inside a
TV, cheaper and safer to take it to a tech. These things can be lethal

Does the capstan spin? If not then check the capstan flywheel drive belt or
the motor itself. I found that Frys had a decent stock of belts.

Failing finding the right size, if you can find one that is too long you
could try shortening it. You'd need to cut it on an angle, and weld it with
perhaps a bicycle tube repair kit that uses heat to fuse.

Hi Homey and b

Yeah, it's a real problem with these Sonys. The trick is not so much the
length of the belt - although it *is* an odd length that's not one of the
readily available general replacement sizes - it's more the width. Although
a flat belt, it's narrower than they usually are. When a standard width belt
is fitted, it rides on the capstans with a slight overhang - just enough to
catch on the back of one of the other pullies. I've even tried cutting down
the width of a normal belt with a scalpel and steel straight-edge, but it is
virtually impossible to do it with enough accuracy such that the belt does
not then ' wander ' in normal use. It is ridiculous, considering the crying
of all the green eco-warriors now about electronics going to landfill, that
Sony can / will not supply such a simple item. There is no excuse for not
stocking it, even if they buy that deck mech in. I've done a lot of them
within warranty period, so a whole new deck is supplied. I used to keep them
in the fond hope that something else on there would become useful in the
future, but now I just bin them.

On ' adjusting ' the size of normal square belts that are an odd length.
Yes, I have done this on many occasions over the years, even on the small
1mm types. I tend to cut the ends dead square with a razor blade, then apply
a single tiny drop of cyano-acrylate "superglue" to one cut end, using the
point of a needle, then bring them tightly together by hand, and hold for
about 1 minute. The slight ' squeeze-out ' of glue can then be removed with
a piece of very fine oxide paper ( car paint wet 'n' dry rubbing abrasive
paper ). As soon as you attack it with the paper, you will see if you have
got a good bond. You can then stretch the belt about without a problem.
Superglue bonds neoprene like the proverbial, and I can't remember ever
having had a belt thus ' manufactured ', come bouncing back.
