Firmware version : ver.1021.1- If customer turns unit off and back

on,. Loss of channels. the TV displays "Weak or no

signal". the cable system's setting always

changes from "HRC" to "STD" though he set it to "HRC" before

- The problem happens at the region where the cable system is "HRC" or "IRC"

No Service Bulletins

Hot Item:Distorted Video: Use the internal

test patterns in both the main board (FE2) and the Logic board located within the service menu test patterns to determine location of distorted video prior to removing the rear cover. Refer to GSPN
