Pioneer 50" Plasma

Archived from groups: alt.tv.tech.hdtv (More info?)

I have a problem with the above only when watching SD or HD TV.After the tv
has been on for about 15-20 mins the picture staggers for about 1 min then
it will be fine for 2-3 hrs and then it will do it again. In the past 2
months Pioneer have changed 3 media boxes 3 set top boxes (diff Brands inc
pioneer)and last week pioneer delivered a new screen. I have changed 2
sets of RGB leads & put an amplifier on the antenna.I have also shifted it
to another point in the house with a new quad shield Rf lead and it still
does it.i have had a 42" fujitsu plasme for 2 years in the other room on
the same antenna and it has not missed a beat the only other thing I can
do is replace all the coax to all the points with Quad shield but I was
hoping that someone out there knows how to fix it as I don't think the
antenna is the problem.
