I have a Panasonic CT32d32.  When I turn on my TV I see a grey screen
with multiple horizonal lines.  Sound is good but there is no picture.
The good people @ Circuit City have told me I need a new Video Card @
$350.  However, I cannot locate that part at Panasonic's website.

Greetings, all!
I recently purchased a Magnavox Hi-Fi VCR, model # VRU364AT21, from a
pawn shop.   The unit includes a remote control which apparently can
also control a television and a cable box.  I'm wondering how to input

Someone just posted a ton of service manuals in
alt.binaries.e-book.technical
Get 'em while they last, folks!

   I don't service as many Sony TVs as other brands, but I can't remember the
last time I had to replace a FBT in a Sony TV.  This set apparenty has a bad
FBT based on tests I performed and using a scope (ringing) with a loop around
the FBT core.  The V reg (+135V) is good using a ...

Someone wants me to look at their Sony KV36XBR400 which failed and now only
makes a click and degauss sound when turned on. Obviously a power supply
problem, is this something that's common for that set? I'd like to have an
idea of what I'm in for before I go over there and tear ...

I have a couple of older controllers, which no longer have the satisfying
click when pressed. I read a tip on-line about a year ago that explained a
simple technique for restoring the "click" to the rubber pads under
controller buttons. It stated a specific substance to use, which I ...

I've been reading about problems with Aiwa CD players and I was hoping
if anyone could offer any advice for my situation.  I have an Aiwa
CXNMT90 system whose CD player will attempt to read a CD where the
head will spin the disc several times and eventually give up after a

I think this is the last of a long list of problems this set had. Remote
itself is fine, works with a P5075, remote sensor seems to be good as well,
I measure a voltage change at the main board where the front panel plugs in
when any button on the remote is pressed. No response from ...

My tv is broke and I cannot afford to have it repaired, so I want to give  
it a shot myself, so pleaee any input from you is greatly appreciated.
I have a 6 year old 32 inch sony widescreen tv and yesterday the problems

Leading Edge (Daewoo) 14-inch monitor.  Works fine but there is a buzzing or
steady arcing sound, apparently from the flyback transformer area.  Is this
a failing flyback or something else?  I am familiar with high voltage
precautions but haven't been keeping up with monitor repair. ...

I'm using a portable DC TV (Magnavox CCR095) on my boat in marginal TV areas
(low signal). Can the auto-blanking in the RF front end be disabled to allow
for marginal reception? Weak stations go from "watchable" to "blue screen"
over and over. Is there a threshold pot in the tuner ...

Norcent DVD remote KF 8000B, worked for a month,
than totally dead. checked all the solder joints and cleaned everything,
batteries are good. is it just a real cheap made remote, or a common
problem? universal remote works,but only half of the functions.

    I've got a Philips "Sound Enhancer" IS 5021 from around 1994 or 1995 in
for service. It is an A-D and D-A converter that Philips does not
acknowledge the existence of.  There is an external power supply based
on a MC34166T IC.  The supply has an open fuse made by Wikman (sp?)

Would really appreciate if somebody could send me a schematic for the Nokia
446 Pro monitor.
I have some burned SMD mounted components that I can not read out the
values.
