6 times red light blinking is error code that shows " no DD 6V output " Check GM board, its known as Power Supply board.
Above is technical explanation of error code for techs.
Let me know further question, if any.

    ==============================================================

    If you want to repair power supply on component level that needs fair knowledge of electronics, tools to check/ test components, soldering tools and skills to replace defective parts.

    Please check +6 volts at IC1607 pin-1 and output +5 volts ate pin-3

Problem with KDF-70XBR950 TV. The TV won't come on. The power light blinks green for a few seconds than it blinks red for a while until it turns solid red.


How many time it blinks will tell you what the error is. This site will provide you with the service manual and on page eight of it will give you the list of blinks vs problems.

I recommend that you check the power supply for any blown or faulty capacitors as well as checking all the plugs on the tv internals( all the plugs that plug into the circuit boards) Good Luck.
