What special interfaces are you talking about on ALL newer HDTVs? Which
manufacturers require factory authorization to get service manuals? I
service many major brands and don't have problems getting manuals for most
of them. I use no special interfaces on the sets that I service. Computer
monitors and many of the LCD and DLP projectors are another matter, but for
consumer HDTV most are not that big a problem.

Also, many repairs are not done in the home. Lots of sets have light boxes
or easily removable chassis and CRTs. We do minor repairs in the home and
pull to shop for majors, leaving only final alignments on reinstall.

I can't imagine that anyone is still profitable in the consumer TV business
not working on PTV.

It is mostly component level repair in the house. ALL the newer HDTV
sets REQUIRE special interfaces and factory authorization in order to
even be able to get the service manuals. Plasma sets are all board
level repair via the manufacture, NOT PTS. The least expensive boards
on the Plasma sets are typically $350 authorized servicer cost.

I would expect you will have a significant investment in order to start
doing repairs on anything current technology.
