Re: Problems with Sony Bravia HDTV

Good point - - in my situation I watched the VCR output on a different
monitor, so my isolation device was not shorted out by an additional
composite or S-video cable from the VCR to the Sony TV. Looks like the only
solution for low channel noisy picture is to get rid of the filter
capacitors on the VCR AC input, eliminating the AC leakage. I'm not sure
that would be a legal modification.

The 1st thing I would try is to eliminate the VCR from the situation!

Connect the cable directly to the HDTV. Depending on the results from
that experiment we can decide what to do next.

Generally, the optimum solution is to connect the cable to a splitter,
and connect the two splitter outputs to the TV and VCR. Then run
composite or S-video cables from the VCR to the TV.

Hello. Recently, I bought a Sony HDTV. Specifically, I bought the
following TV:

40-inch Bravia S Series LCD Flat Panel HDTV, model number KDL-40S3000

Here is how my TV-cable-VCR system is set up. My cable provider is
Comcast, and I have only basic cable. Thus, my cable consists of
nothing but a coaxial wire (coax, for short). The coax comes into the
house and is plugged into the VCR's "in" slot. Another coax connects
the VCR's "out" slot to the "cable" slot on the TV.

----------

There have been a few problems with this system:

1) On the HDTV, the digital channels look good. However, the analog
channels sometimes look good and sometimes look bad. By "bad", I mean
that the channels are full of snow and are grainy.

For example, channel 7 (the ABC station in Chicago) might look bad,
but channel 7.2 (the corresponding digital channel) looks great.

Also, the analog channels are inconsistent in their behavior. On some
days, the analog channels will look bad; on other days, the analog
channels will look good.

So, why are the HDTV's analog channels looking bad? And why are the
analog channels looking bad only sometimes?

----------

2) Another problem seems to be my VCR. This is a Sony VCR with an
analog tuner (model number SLV-N750).

The VCR is set to analog channel 4. Here in Chicago, channel 4 is also
a Spanish channel in my cable lineup.

One thing that sometimes happens is the following: I turn on the TV,
and I turn on channel 4. The channel looks good. However, when I turn
the VCR's power on, the channel starts looking snowy and grainy. Note
that the snow happens when I simply turn the power on. I have not yet
pressed the TV/video button on the VCR remote control in order to
watch TV via the VCR tuner.

So, why does turning on the VCR cause channel 4 to start looking bad?
Is my VCR properly connected to the TV? Are my coaxial wires weak or
malfunctioning?

----------

3) Another problem with the VCR is the following: Sometimes, when I
play a recorded tape, the image is snowy and grainy. Sometimes, the
image is good.

Prior to the HDTV, the same coax that connects the VCR's "out" slot to
the HDTV's "cable" slot also connected the VCR's "out" slot to my old
analog TV's "cable" slot.
The material on the tape was recorded when my VCR was connected to the
analog TV (Mitsubishi brand), and the tape looked good on the analog
TV.

So, why does the image from the VCR tape look bad on the HDTV?

----------

4) When my VCR was connected to the analog TV, the analog TV *also*
had some problems with snowy analog channels. However, in the case of
the analog TV, the only analog channels that had problems were
channels 2, 3, 4, and 5. These were the channels that were closest to
channels 3 and 4, the VCR channels.

On the HDTV, the analog-channel problems are not limited to just a few
channels. On the HDTV, most or all of the analog channels experience
snow and graininess.

----------

5) At one point, I was trying to watch the digital ABC channel, and
the TV said "no signal". Hours later, the signal was there again.

Also, our cable subscription is very basic, and we do not get channels
like "Comedy Central" or "Cartoon Network". However, one day, I was
scanning through the digital channels that we have, and I saw "Comedy
Central" and "Cartoon Network". The next day, we again did not have
these channels.

So, what is going on with these signals? One day we have Comedy
Central, and the next day we don't?

So, please give me some advice. I appreciate any info.
