Sony KV-32S40 has audio but no picture
 

I have a Sony KV-32S40, which I purchased in December of 1998. I have
not experienced any problems with it until today. I turned the TV on
today and everything was working fine as usual. After about 3-5
minutes the screen turned black but I still had audio. I turned the
TV off for a couple of minutes and turned it back on. It appeared to
be working fine until about 5 minutes later it did the same thing.
The screen just turned black. I turned the channels to make sure that
it wasn't the channel and turned on a different TV in the house to
make sure that it wasn't the cable. I let the TV set all day before I
tried turning it on again. After about a minute, the screen started
getting a bunch of lines in it and the picture appeared to be
shrinking from the bottom of the screen to the top of the screen.
Then the screen went black again. I again let the TV set for a little
while and tried it again. Now I don't even get a picture when the TV
comes on. I still have audio and can even switch channels, but there
is no picture. The red light on the front of the TV that says
"Standby/Timer" just keeps flashing. I didn't hear any noises when
the picture was going out. I talked to a repair shop today and they
said that the picture tube is probably bad and that it would cost more
to fix it than the TV is worth. I feel that I am a technical person
but I have never worked on a TV before. Does anyone know what this
sounds like or have any suggestions?

Whatever you do, do not take that tv to the "repair shop" that you talked
with. There is no way they can determine that the picture tube is bad
without doing proper diagnosis. From your description it does NOT sound
like a picture tube problem.

You need to take the tv into a reputable and good shop for proper diagnosis
and repair. Given the description of the symptoms I would start by checking
the vertical circuit for intermittent solder connections or weak capacitors,
and then check for other common solder connection problems.

Typical repair if you take the tv into a reputable shop around here varies
between $90 and $125 total for 90% of the repairs on that size of tv set.

Agreed, call around and find out which service is SONY authorized and
experienced in repairing these sets. Take it to them and ask for an estimate
of repairs before getting in too deep, Then make a choice if you care to
actually have it repaired.

Thanks for the advice!! I took it in to a different shop today. They
said it might be a week before the can get to it. I will post what
they tell me.

Hi BR,

I am having the same exact problem with my kv-32s40, how did you make out
and the repair shop.

Achan,

I just started experiencing the EXACT same problem on my kv-32s40 today! Wondering if I should take it to the shop - what did anyone find out about the cause of the problem and how to fix it (or the cost to fix it)?

Is there any On Screen Display at all? Any indication of High Voltage being
generated? Has there been dfnative diagnostics preformed on theteles yet
that you may post to this N/G?

If you have the on-screen display, this means that there is high voltage,
and maybe proper biasing to all three electron-guns in the CRT. If there is
no on-screen display, this means that there may not be high voltage, or
there may be a bias or drive problem to the CRT. Also, a common problem with
these sets is that a bad CRT will cause the set to have no picture. If there
is a video drive failure on all three colour channels, there will also be no
picture.

An experienced tech should be able to diagnose the basic cause of this fault
in a matter of about 15 to 30 minutes, unless the particular fault is
complex.
