Lots of generalizations, Asimov. They don't tell the whole story. They are
in some cases very much WRONG, like saying "nearly perfect images even as
the tube ages." The partial truth in your observations also adds nothing to
this guy's problem. We still fix most sets like his profitably, BTW.

Well, modern tv design has become much more integrated into very large
scale IC's (VLSI). Basically you find integrated functions of a tuner,
an audio processor/output, a microcontroller, a video processor, a
vertical output. Only the horizontal output and deflection is still
mostly discrete but these are under direct control of the
microcontroller. TV's are mostly empty space inside as nearly everything
can fit on a single small board including the power supply regulator.
The rat's nest of wires, pcb modules with myriad jumpers, and countless
adjustment pots are a thing of the past and a good thing too! This means
tv's consume a lot less power and the computer control means nearly
perfect images even as the tube ages. The savings in materials also mean
a large reduction in price to the point where repairing tv's is
basically unprofitable except for high end projection models and the
latest hdtv technology to some extent.
