This Sony STR-GX10ES receiver works great apart from the tuner seems
to be in the wrong mode.  It tunes from 79-90 MHz on FM and 522-1611
kHz on AM in 9kHz steps.  I think this is the Japanese FM band.
There's no obvious switch for changing tuning modes and I'm sure this

I recently got an old Canadian NT Meridian M9009 + phone, which works fine as a phone (dials out and receives
calls). The other functions, like a number display, Hold, Save, Rls, and some way of saving phone numbers to
buttons marked 1 to 5, a volume control, aren't accessible ...

Thanks Sam and Alan for causing me to rethink along my original lines
for wiring.  The series connection of the field of course was for the
higher voltage and the connection I orginally settled on as being for
the low voltage was indeed for the high voltage.  What I missed was ...

I've got a bulky Sony Trinitron XBR exhibiting weird symptoms.  First I
noticed that it was taking an inordinately longer time to come on when
turned on.  It takes anywhere from thirty seconds to two minutes to get the
degaussing click and for the red light to start flashing on the ...

Howdy all....Have been asked to wire up an old 1hp 115/230VAC repulsion
motor for the higher voltage with a desired rotation.  This is digging
back a little far into the memory bank for me......4 wire winding and no
diagram or legend on the wires but I tried the windings in ...

I ask you to read this letter till the end! Don't treat to my words
with indifferens. On Your understanding it will depend my fate and the
fate of my child!

I have a Sony KV1370R that is coming up on it's 20th year of service.  The
set works fine except that recently it "jumped" off of the table and the
Capacitor in Series with the UHF input was destroyed when the bulkhead
mounted F-Connector was ripped out of the back of the set.

I recently acquired (from the dumpster) several Sun Microsystems 20"
monitors, model GDM - 20D10, which appear to be Sony Trinitrons on the
inside. They are really nice when working properly, but were
manufactured in 1994 so probably aren't worth sinking $ into.

Christmas. It had to happen. My Grundig TV, ST 55-727, went duff. Sound
perfect, picture in Ultra ultra wide screen mode ie, 3cm in center. Ok
for a postman's view of programming but my other half not well pleased.
Vert's gone. Anyone with a cure?

Can anyone please help me?
I am working on a Crest 1400 power amp.
I replaced all 6 pairs of b600/d555 outputs (1 chan).
The amp played fine for 10 minutes at low volume

I'm looking for a Digital board for a Sony STR-DE945 I'm trying to
repair. Let me know if you have one you would like to part with.
Thanks.

Hi there I have one of these 28" widescreen units. It has developed the
fault once fully warmed up:
red lines in picture, brightness flickers, intermittently switches off.
 This is listed in the Euras database http://www.euras.com/ but I

I don't have a schematic; I've substituted out a few of the larger
capacitors one at a time (assuming a bad power supply capacitor).  But I'm
just guessing.  Anyone have experience with this model or know of a good
(cheap) source for the schematic?  I've done TV repair in the past, ...

I'm starting to diagnose power supply shutdown problem that has progressed
from about once per month during long period of operation to a regular
failure now within a few seconds of power-on.  I do have schematic repair
manuals, but no diagnostic procedures.

I need to replace the rear flap door of this unit. I have the replacement
part, I have moved all the necessary components from the old to the new one,
but cannot find how to access the screws retaining the hinge pins. I have
had all the sections apart from all sides but still cannot ...
