Sony tube tv going bad?

Hello:

This has not been a good week. Last week something killed my (14yo) gas range.
While baking dinner it made a loud snap/crack sound like a light bulb exploded
and stopped working. Clocks dead, ignitors for the stovetop and oven won't work.
Looks like I'll have to replace it.

Now last night our Sony 30" tube tv (aprox 7-9yo) started to act up. We were watching
a dvd when the picture went to black, but the sound was ok. I immediately thought it
was a defective DVD but that's not the case. I turned off the dvd player and tried to
watch some tv but had picture problems. As I flipped channels the picture would be ok
for half a second then go to half brightness, freaky colors and distorted image, then pitch
black. The aux inputs Video 1, Video 2, etc. also were effected. Turning the tv off for a
minute and then back on fixed it for a while then it happened again. The tv seems to be
working ok so far today. So, what do you think? Tuner crapping out or the picture tube
going? I thought the Sony Trinitron sets were long lived and pretty much trouble free...

Thanks, Phil

I expect a range -- gas or electric -- to last at least 20 years, maybe 30.
This sounds like a power-supply problem that ought to be fixable -- though
whether it will be at a "reasonable" price, I don't know.

It /can't/ be the tuner, because the line-level inputs also have a problem.
My guess is the chroma chip, or some nearby component.

Sonys do seem to be reliable. My KV-1920 lasted more than 20 years (needing
only a $70 power-supply repair), and my current 400-series 36" flat-face is
almost 10 years old, with no problems.

Get the set properly checked, preferably by a Sony authorized service rep. The fault can be the power supply, scan amplifier, pin amplifier and or a combination of these areas. Considering the age of the set there are many types of components that may have failed.

A defective CRT will usually be fading out, not be be able to color track properly, or have focus issues before it fails. Normally a CRT fails very slowly.
