This TV shut downs every 10 min. I resoldered
the PSU and deflection area and replaced the high
ESR caps but no help. TV is old and have no sleep
function. Does anyone have any idea as to what's going on?

Thanks in advance,

Troubleshoot for thermo sensitive components, especially in the power supply
and the scan circuits. I have had capacitors become thermo sensitive, thus
causing sets to shut down.

Other areas in the set having poor or cracked solder connections inclusive
of the regulators and horizontal deflection areas. What is the regulated B+
level? Other diagnostic measurements and test's you already have preformed??

All the voltages are OK included B+ which is 135V.
No ripples, nothing seems out of ordinary. I resoldered
the deflection area and PSU. What puzzles me is that
TV shuts down excatly in every 10 min. As far as I know
( I don't have the remote and the manual) TV does not have
any timer function. Any idea?
