[PLUG] Monitor... dead audio

[Chuck Hast]

Yes, I have tried both inputs, and zip. There is something wrong in the
audio
path. I can feed another TV with the HDMI cable from the RPi and get good
audio, so the issue is with the TV/Monitor. I can tell you this much
Westinghouse
is useless, I sent them a note to the address given for such issues, they
sent
me a USER manual which I had stated very clearly that I had. Then they sent
me a 800 number, I called that, they told me they were going to send it
right
out to me, they sent me a USER manual, called them and told them that I
already had the USER manual, and that I needed the service manual, guy told
me he did not have it, asked to talk to a manager and he hung up on me.

Called back, got a chick, she pulled up the trouble ticket number and put me
on hold, and never came back online. Whatabunchaputzes...

I have looked high and low for it, I am trying to go through the FCC it has
a
FCC symbol on the back but no grantee code. So not sure what is going on,
flat screen tv/monitors fall under part 15 because they radiate, so they
have
to have gone through the radiation testing, unless the label is boggus.

Once I can get the grantee I will KNOW who the actual manufacterer is, and
I can try to go to them. Or FCC may have it on the site, I have got diagrams
of devices off of the FCC site before.
