Not a simple question. What makes a good or bad set is a moving target.
Its not just a good pix. Its Pix, audio, serviceability ( both physical & circuit
design ), parts availability, tech back up, and on ........
So a little finger pointing now.
Warwick ( sears ) are all toilets but well designed.
GE improved with SS sets. first ones OK. The EC chassis was trash due
to griplets. The PC chassis was a solid great running set but when
they finally got it right they pulled out of TV.
Same with Admiral. The M10 chassis was highly unreliable. Other chassii
for consoles were very good sets. Latter AOC chassis one board sets
were very good for a few yrs. Then they decided to limit the FBT's life
( smoke ! ) to 2 years !!
Maggy sets were decent but prone to MANY cold joints. The best they
built was the C-1 chassis that was as good as anything out there.
Enuf fer now
