Measure Vsus
(*3)
at pin
1 of CN P11 and Vda (Approx. 75V) at pin 1 of
CN P12. Plug in the TV and turn it on.
Note: CN = Connector

Are
any of these
voltages
missing?
Warning:

connection
(*1)
= The reference number of the sustain data connector is different
in some of the models:
TH-42PX80U = SS23
TH-50PX80U = SS23
(*2) CAUTION:
Before connecting P2/SC2 or P11/SS11, discharge is
necessary to prevent potential shock caused by VSUS
.
(*3)
Make adjustments according to the value provided on the label
normally found above the SC board or the SS board
(*4)
Place a jumper across pin 8 and 10 of connector P12. The unit
will not enter the standby mode without the jumper.
(*5)
= When measuring Vsus and Vda, make sure to place the
meter’s probe on the pin indicated before turning the TV on. This
way, a voltage reading can be obtained before the TV shuts down.
Does the power LED stay on
when the TV is turned on?
