Voltage Distribution (Panel Drive Voltages Vsus)

Analysis of a shorted Vsus condition

Vsus is generated by the Power supply and is used by the SC and the SS boards.

A shorted Vsus is usually caused by the SC board or the SS board and very rarely the power
supply is damaged when this occurs.

To check if Vsus is shorted, unplug the TV and discharge any possible residual charge from
the Vda and Vsus lines. (Use a 500 ohms resistor at least 5W).

Then measure resistance or continuity on pin 1 of either connectors P2, SC2, P11, or SS11.
(A resistance reading lower than 1K (1000 ohms) is considered to be abnormal.)

If a short circuit is found, isolate the SC and SS boards to determine which board is defective.

Depending on the model, a short circuit of the Vsus can cause a 3 fast blinks or a normal 7 blinks condition.
