i think it is the cheap chinese parts. with some planned obsolescence thrown in.
and price is the cause. if these same parts were made in the USA, a 32" tv would cost $1500. and most everyone would still be watching SD.
$2000 for a receiver . if that were par, these forums would be pretty lonely.
afa my 32" tv crapping out. i am going "round & round" with toshiba for a warranty repair.
If you knew a fraction of the technology that has to go into a modern Hi Def TV, receiver or pre pro, you would understand the severe disconnect.
Basically at the prices you are prepared to pay you should be watching SD.
Do you realize the size of the chips and spacing of the components on a board is now an issue?
The finite time, placing and characteristics of a board now determine whether it will work at all.
My son designs chips and is an expert in electromagnetic modeling. Gone are the days when you could make a breadboard circuit and expect it to work. He has to do a lot of advanced theoretical math down to the nuclear physics level of the components and circuit board.
It takes practically nothing to really upset these circuits.
He sees much more unreliability in your future, unless people are really prepared to pay the piper.
These failures are very costly to industry. I think the low end of the market actually will disappear, because it is rapidly becoming impractical.
So it may get lonely.
However if we were really the center of all this design and manufacture, there would be people to pay the piper, because we would have high paying jobs; lots of them.
As it is we have dumbed down our education to where the population is becoming as stupid as pig dribble. But the Koreans close their airspace on high school exam day, and have now placed a curfew on children and gaming.
The world is getting more and more complicated by the week, and our population are becoming stupid and irrelevant. It is time to wake up and smell the coffee.
There are much broader issues behind your failures than you realize.
