Hi all: My 15-yr old Toshiba 27" crt television has recently developed a
problem which is that approx 15 minutes after being turned on, the picture
bows inward on the left and right sides. Then, after a few more minutes,
the picture resolves and returns to normal and remains perfect for the
remaining time the tv is on. If the symptom described above means the crt
is wearing out, so be it, the set will soon be history. However, I'm
wondering whether some other, replaceable part, might be going bad and
causing the temporarily distorted picture.

Would appreciate any suggestions re. probable cause(s) of symptom described
above. Am basically novice, but handy and with soldering skills, and have
done a few simple tv repairs in the past. Thanks for your replies!

Probably a tube is getting weak. Remove the back, label all the tubes
for location on the chassis, so you can put them back in the same
socket. Pull out all tubes and take them to your local drugstore or
hardware store and test them in their tube tester. Replace any bad
ones and you should have a good working tv for several more years.

I doubt a 15 year old TV has any tubes other than the CRT.
