SMPS TEST
: Removing connector P814 will force the SMPS into full run mode.
Only do this with AC power removed then reapply AC power.

Complete testing of the SMPS requires that you load VS
with 2 100 watt light bulbs with P811 and P812
unplugged to verify it is functioning correctly.
TIP:
If A/C DET is low or missing, Remove AC Det (pin 28) out of P814 and
jump it to any pin carrying 5V STBY. Then reapply power to the unit. If the
TV now stays on, suspect a defective SMPS.
The 17.8V on pins 1 ~ 4 is
derived by the Y-SUS PWB.
Voltages are reference to floating ground.
