I have a JVC 27 inch tv with standard picture tube. Its about 15 yrs old
now and I like the set because it has a built in surround sound system. My
problem is that it appears that the picture tube is getting weak. When I
turn it on, it is very bright, like the contrast is turned way up, but as

You have unwittingly answered your own question. Factory torched
contrast settings are a sure way to sell TVs, but are sure to kill CRTs
like yours and CRT projection sets early. Turn down the contrast as
far as you can and can still see the picture. 15 years the phosphors
on the tube face are probably toast. You may also bring up the
"brightness"(dark shadow details) a little. This will bring out the
light-gray pinstripes on a darkgray suit.

time goes on, the picture come closer to normal, but it appears the colors
are out of alignment as well. What I'm wondering is, is it cost effective
to replace the tube? If its not more than a couple of hundred dollars, I
think it might be. Any tv techs out there know what a ballpark price on
something like that might be? Thanks in advance.

Color maligned - is it too red, too blue, or oversaturated in general?
Turn color down until it just appears b&w - then turn it back up until
color reappears. Think: Do the colors on that NASCAR paintjob really
bleed into each other like that?? It's time to get the overbright,
cartooney image of TV imposed by manufacturers out of your mind - NOW.

As for tint - trust me on this - tune to History Channel or C-Span when
a closeup of a speaker is on. In the absence of blue bars or test
patterns - simply adjust the tint until people look
like...well...people!

These contingency settings will get you a vieweable picture while you
evaluate your options.
P.S: These lowered settings will after a while reveal the ringing and
artificial lines the sharpness control is no doubt adding to subjects
on screen - turn it down a little on a daily basis - you will start to
see details previously lost when color and contrast were set to guide
planes into municipal (laugh).

regards and happy viewing!
