Strange Sylvania Problem

[[email protected]]

Sylvania console TV circa 1990. Model RPS 590. When set is unplugged
from the electrical socket and then plugged back in, it can take up to
a week (or longer) before the set will come back on. It's done this for
about 8 years. This time 9 days have passed and the set is not working.
Yes the electrical socket is hot. I have power to the main circuit
board, no fuses blown. Any ideas? TIA

Given the generic nature of the symptom description, it is probably a
component that was thermally sensitive, likely a capacitor. Need to do
some basic tv power supply troubleshooting to determine the cause now.

Why not just bring it to a service center and have it properly
serviced? This is not something that without the proper training,
tools, service manual, and experience you are going to fix yourself.

Broken/cracked solder connections have accounted for about 40-50% of all the
things I have fixed. A light tap in the area of the suspect problem is often
enough to see if a loose connection is possible.

A close and careful examination of the solder joints is called for. Since I
see you have already measured power going into the board. Good luck. Scott
