    The red light blinks 9 times, pause, 9 times, pause 9 times...........

    I just ran the self diagnosis test and all numbers are followed with 0's except #9,
    #9 code ZCD is 255, does this narrow down the problem.

    OK, 9 times red light flashing shows problem with Sound output chip that seems defective.
    Please check following to fix the issue.

    +/- 19V line is shorted. (A, B boards)
    IC708 is faulty. (A board)
    PS701 or PS702 is opened/ blown. (A board)

    Note that above info are applicable for Sony KP-51WS520 tv as your question shows that is model number of your tv, iftv model number is different, let me know to reconfirm cause of problem.
    Thanks.

Won't turn off unless unplugged


Ther eis a stand by function on the Television. If you have the owners manual read about that function. Th ered light stays on because it is programed to come on a t a certain time. Go to menu and find the stand by function.
