Hi again,
   Would anyone have or know where I could get a schematic for this
old portable B&W TV which was once sold in Australia?
   Thanks!

G'day,
   No, so far I've only e-mailed High Country Service Data without
getting a reply.
   Thanks for your suggestion - I hadn't thought of Speedy Spares even
though I've dealt with them in the past.

No worries - they're pretty good for schematics for most of the major
brands/models. I haven't been in the repair industry for a few years, but
their email address used to be:  sales@speedyspares.com

**  Well,  I have a schem and PCB layout for a  " H.M.V. 1184 "  12 in. B&W 
portable,  right in front of me.

Cos I actually own one -  and it is a goer.

Care to carbon date it,   anyone  ?

You'll probably still get a reply from HCSD - he's usually pretty good.

Hi,
     You could try Television Replacements in Doncaster 0398504144 they have
lots of circuits for older sets,and they used to be the Panasonic agents.

Don't you know Phil here is into "Verge Side Electronics"? 
Anything electronic left out in the street in Summerhill 
gets spirited away at night.  BTW ask Phil how old his CD

Thanks to everyone who replied -  appreciate it.

BTW, I've got a Sony CDP101 too. :-)

   Unfortunately it has the symptoms of a dying laser... skipping and
trouble finding tracks. It was great before that happened though.

** Is the disk draw moving sluggishly ?

If so, the nylon gear lubricant has gone sticky.

WD sprayed into the affected areas does wonders.

Might fix all the symptoms.

I doubt that the disk drawer is the cause of this problem, more likely it's
either the laser diode going down or a problem with the sled. (I'm assuming
that you've cleaned the lens.) Either too much wear, or bad lubrication. The
first is hard to fix, unless there's a power adjustment trimpot in the
circuit, but if it's only a lack of or sticky lubricant on the sled rails,
re-lubricating could fix it. In the case of Sony Playstations, when the sled
rails are worn, turning the unit upside-down often helps. (No good in this
case)

How old is that?

I've got a Sony D-22 (walkman-size) that I bought ex-warrantee
repair in about 1989 IIRC, and it's still going strong. Makes
an awful noise if you accidentally try to play a data or MP3 CD,
but still...

   I haven't powerd it up for a long time. No, I haven't tried
re-lubricating the sled rails. If I ever get time, I might give that a
try. I was assuming it to be an electronic problem, and we all know
that technicians should never assume anything. :-)

   I bought it in 1984, back when domestic electronics was built for a
long service life way past the warranty period. :-)

  **  As do I  -  kindly read what I wrote to Bob.

**  The " sled " uses the same sticky grease.

   Must be 20 gear wheels and other bits involved.

 **  Bad grease is my hunch.

Seeing as 100 % of  CDP 101s have that exact issue.

Shame you have no clue.

   Maybe you should dig up one of those newfangled ESR meters and check

Phil, you just can't help yourself, can you?
What did I say to upset you, and when will you grow up?
Or maybe you're right, I have no clue and am just making things up. I know
that you're not too bad with electronics - it's a shame that your social
skills aren't up to the same level.

Phil, I feel very sorry for you. You really are a sad case. I couldn't be
bothered wasting any more time on you. I hope for your sake that you
eventually sort out your problems. (My advice is that you seek help, since
obviously you haven't already done so. You're sick.) I didn't say anything
offensive about you, so what's the problem? I was only trying to help Bob.
Anyway, you've about done it for me, as far as these electronics newsgroups
go - I won't be back.

There's nothing superior about Phil.  He just thinks he's a legend in his

Here's something that Philthy would appreciate -
