Not Panasonic / Quasar. Build style distinctive, much neater &
easy to work on.
Most of these 5" sets came from Korea & built by Gold Star,
Samsung or Orion. There were also quite a few almost unknown
brands building clones & branded sets all around Asia. They can be
almost any brand inc some big US ones.
Unless someone says "I got one ! " I think all you can do is check
both sides of the PCB's for brand or logos.
