Default 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


Sounds like the circuit that monitors the crt called the IK circuit or
something like that is cutting out the video because the circuit
thinks the CRT is going out of balance for the 3 guns.
