8 Blinks Error Code (TC-P42X1) Circuit Explanation

On this model, only the circuit used to monitor for physical connection between the panel and the SS board is used to trigger an 8 blinks condition. The energy-recovery- circuit portion used to monitor the operation of the sustain drive circuit is located

on the SC board.

Under normal condition, Q16280 is on.

When Q16280 is on, a low is provided to the anode of D16280 (D280).

If one of the FPC cables is open, Q16280 turns off and a high is provided to the anode of D16280 (D280). This high is provided to pin 66 of the CPU in the

A board. When this happens, the TV shuts down and the power LED blinks 8 times.

To determine if the 8 blinks is caused by the A board, SS board, or the Panel:

•Isolate the SS board and check if the TV stays on when it’s turned on.

•If the TV does not stay on after disconnecting the SS board, the A board is defective.

•If the TV stays on, then the SS is bad, the FPC cables are open, or the Panel is defective.

To isolate the SS board for 8 blinks condition:

Remove SS23 and see if the TV stays on
