They'd likely just replace the entire PCB if they can still find one.
Probably would cost you around $300. The days of a repairman with the
skills to get in their with a scope, troubleshoot the problem, and
solder in a new capacitor or drive transistor or replace the flyback
transformer are long gone.

Of course people are giving away CRT TVs for nothing on Freecycle, or
worst case selling them for $50 on craigslist, so it may not be worth
getting it fixed.

If this is a thermal problem (it might not be, but probably is), wholesale
parts replacement in the deflection circuitry might fix. You might also try
squirting the parts with liquid freezer.

It's probably more cost effective to just get a new TV.

This sounds like a capacitor in the vertical/frame circuit. Should be
an easy fix and a part costing cents - but given the size of the set,
I imagine that taking it somewhere is tricky. A call out will be
prohibitive, cost-wise. So I suggest you have a go - do you have a
soldering iron and som e solder? (available in a hardware/hobby store
I imagine). if you can post some pics of the main pcb , we can guide
you to the likely problem area. It would be a pity, and wasteful, to
dump an otherwise working set....

However, as the saying goes, "You get what you pay for."

First (and less important), a 32" HD TV has about 20% less vertical
picture height thatn the Quasar. Yes, to a certain extent it makes up
for it by improved resolution. Still, the objects on the screen are
smaller than they were on the 32". You have to go to a 40" HDTV to
get the same image height.

Second, the $300 TVs are house brands, or otherwise have very
limited service availability. The Insignia and Dynex brands available
at Best Buy may look good while they are in teh store, but once the
warranty expires, the buyer is SOL.

The Vizio, Viore, and Haier TVs represent an even worse value. A
failure under warranty will get you a replacement TV of uncertain
history. In the case of Vizio, the full warrant only covers the first
90 days. After that you have to ship the Tv to Vizio AT YOUR EXPENSE
to get a replacement.

I almost agree with you. It might be worth spending a few minutes
with freeze spray and a hair dryer trying to find the thermally
sensitive component (probably a capacitor). If that fails (or reveals
other problems), it's not worth it.
