I have a 20 year old fisher 25" tv and it shuts itself off randomly. If I unplug it, it will stay on a few hours, but after a while it will shut off every 5 minutes
20 years is too long and the components ternmial might be loose or crack at this time, I'll susgest you look for any dry cold solder on the main board and do resoldering to the components terminal.
