CAUTION: Before servicing receivers covered by this service manual and its supplements and addenda, read and follow the SAFETY PRECAUTIONS. NOTE: If unforeseen circumstances create conflict between the following servicing precautions and any of the safety precautions, always follow the safety precautions.
  • Page 7 8. Always connect the test receiver ground lead to the receiver chassis ground before connecting the test receiver positive lead. Always remove the test receiver ground lead last. 9. Use with this receiver only the test fixtures specified in this service manual. CAUTION: Do not connect the test fixture ground strap to any heat sink in this receiver.

    A. Principle integrated circuits This new generation large screen color television is based on the latest 2in1 chip HAIER8829A-V1.0 developed by Toshiba and haier, integrate with other advance ICs, high performance and simpler circuit are realized by using I bus to communicate with all the other ICs.
  • Page 15 signal at pin 9 and pin 10 which come from N201(HAIER8829A-V1.0), the desired video signal will be available at pin 3, and then sends to AV switcher N802 (TC90L01N) after emitter follower V207 and V214. The pin 31 of HAIER8829A-V1.0 output SIF signal. It will go back into the pin 33 of HAIER8829A-V1.0 after C225.
