Dry joint?

I have a 7yr old (Mfd: 8/96) Panasonic TV model CT-27G11U that seems to
sporadically shut down. There is no popping noise or video changes prior to
shutdown. After shutdown it will not power on again for several seconds.
Some days it will shut down several times after varying delay times (some
quite short), other days - not at all. Any help would be appreciated.
Thank you.
