Well Peter, it looks like the new WEGA XBR is still the same old "Noisey"
XBR as my old 1989 XBR. I hope you have better luck with yours than I did.
The HF noise, worse on 15/17/20 meters, usually became stronger the closer
the TV got to failure mode. Usually the power supply failed. I had it
repaired 3 times in last 12 years. After the last failure this spring, I
went out & bought a Panasonic. No NOISE & NO TVI!!! Didn't even have to
install ferrites on the internal speaker wires like I did on the XBR.
I also got the "buy a RS powerline filter" runaround from Sony. They didn't
have anything else to offer when I told them I already did. I first owned
the XBR when I lived in an apartment so I didn't discover the noise until I
bought a house & set-up the HF shack there. While I had it in for one of
the numerous repairs, I explained that HF noise was eminating from the TV's
case, but they said that's normal! The next shop said they'd try to fix the
HF noise, but didn't. I called to ask why it still had noise on HF, and
they said they couldn't hear any noise. Suddenly dawned on me they meant
with their EARS! They didn't know what I meant by HF. (It's so hard to get
good help these days!) In that same shop, the manager actually offered me a
job when he saw me fiddling with the TV in their lobby while I waited for
them to unload my TV. He said none of his techs could get it to look that
good after hours of work. That should've been a clue.
If anyone wants a Free broken XBR with lot's of inputs & outputs, drive on
over to Omaha and it's yours, ferrites & all! My wife wants it out of the
basement. I keep saying I'll get rid of it after I tear it apart for the
ferrites, but never seem to have the time. Plus it'd be easier to haul out
in pieces; the XBR's are damn heavy!!!
Although the XBR trinitrons have a great picture, the EMI-EMC quality is a
real problem with Sony. And they don't really care since only a small
number of customers will be affected. I recommend Panasonic or maybe JVC
which also has great picture quality, but I have no experience with JVC.
Panasonic just had the better price for features available.
