1) Unplug the AC cord.
2) Connect a 100 Ohm resistor (R) between
pins 4 and 5 of the IC951. This discharges C960
that may still be charged if the Over Voltage
Protect circuit was activated.
3) Remove the 100 Ohm resistor and apply
power to the set.
If the problem still exists, the IC is probably defective.

you have to lift one leg out of circuit and touch the leads to each end of the diode then reverse them and take the second reading,

Use the analog meter reverse your probes you should get no reading one way and get a reading when the probes are reversed. You will need a diode vhecker to test for a leaky diode as often times a diode will fail under load. Its best to replace a questionable diode if you dont have an actual diode checker meter.

Check the connections on your front control panel PCB to see if they are all secure then trace them back to where the plug into the chassis and check the connection there as well

Over Current Protection
Pin 1 of IC951 is also the Over Current Protect input.
The internal FET.s ground return is at pin 2 of
the IC. The voltage drop across R955 and R956
indicates the FET.s current, and is coupled through
R953 to pin 1 of the IC. The Over Current Protect
circuit is activated if the voltage at pin 1 of the IC
exceeds 1.35 volts.
Stabilization and rough regulation are provided by
feedback from pin 3 of T951 to pin 1 of the IC. Fine
regulation feedback is from a secondary supply,
through the Photo Coupler, PC951, to pin 1 of IC951.
Its possible that Diode D953 is leaky allowing the voltage to rise on pin 1 of the IC

Look for 2 resistors off of pin 2 of IC951 R955 & 956 they are hooked in parralell and the tail end of those resistors are grounded.
