I do not have schematics to this set, but check the following in the
power supply circuit: Check resistor values in circuit, pay close
attention to large value resistors that supply B+ to the power circuit
start up for changed values (possible open) check all diodes for shorts
in circuit and all electrolytic caps first in circuit, if read abnormal,
then check them out of circuits.

Hi, I've got a Philips TP3669 TV - Chassis 36Z500-7563
Set would not turn on after the power went out. On two previous
occasions I have unplugged it for 5 minutes and it reset and worked
fine. This last occasion the power did not go completely out, the lights
just dimmed. The TV was not on at the time, but now the set is
completely dead and it won't reset like it used to. I did hear a small
click when it was plugged back in. I know others have had the same
problem with this model. I'm figuring it's something in the power
supply. Fuse is good, I didn't see any obvious signs of destruction
inside. Is this an easy fix? Which part usually fails? Is it worth
fixing? Where should I take measurements to determine the problem? Any
help would be most appreciated before I just go and buy a new TV, but I
hate to if this one is repairable. I'm no longer in the repair field,
but am OK with most repairs.
Thanks in advance,
Jim (vcrfix@xxxxxxx)
