Opinion on Panasonic TAU Repair

[Arthur Shapiro]

I don't pretend to be an electronics heavy - OK?

A couple years ago, a friend and I purchased Panasonic CT-27SX11 TVs a couple
weeks apart.

Mine has been pretty decent over that time...there were two instances where
everything turned green, and two instances where I got an unusual pattern of
concentric diamond-shape rings over the entirety of the screen. In all four
cases, unplugging the unit for a few seconds corrected the problem after
powerdown/powerup sequences failed. I don't know if this is a firmware
problem or inadquate isolation of a microprocessor, but at least it was
correctable.

A couple months ago, his TV allegedly started giving a pronounced green tint
to the main (tuner) input, although I understand not on any of the three
auxiliary inputs. He could not clear the problem, and even turning the green
way down with the on-screen color controls was insufficient. He has finally
ordered a replacement Sony 27" TV, after trying a fancy 30" LCD unit for a few
days and finding it unacceptable.

My question to the gurus: does his particular failure ring any bells? I'd be
willing to purchase his TV as a secondary unit and to have it repaired (or
handle anything obvious in the non-HV circuitry if we're not talking
surface-mount technology) if this happened to be a typical and
easily-repairable failure mode in the TAU TVs.

Considering the age of the sets, and reading your descriptions, the CRT's
are probably going weak. This is to be expected. Also, many of the
components have aged, and are also going to be going off specs. This is
normal for the age and model series of your set.

I would consider replacing them, rather than putting time and money in to
them.
