Hi again,
As I said its problem of +17V and -17V that foes to audio output section of tv and these volts supplied from G1 (power board).

http://www.fixya.com/support/t5290453-kdf_70xbr950_lightning_storm

Since G1 board has been replaced but tv still shows 6 blinks error that means audio output section has problem and most probably audio output chip is bad and causing shut down of +/- 17V supply lines.
Do you have multimeter and can measure volts in tv circuit board?
Thanks.

    afraid I dont have that and wouldnt know what to do with it if I did. Sounds like this one goes over my head. Should I just replace it and if so is there a part number or should I call a repair man and if so any suggestions in my area Mokena ILL

    OK, there is simple test, unplug connector CN1624 on G1 board that provides voltage supply to audio output ICs on A board. Turn On tv and it should turn On if audio output ICs are cause of problem.
    If tv still gives 6 blinks error then its serious matter because next suspected board is C1 board and its complicated. TV repairman is needed to replace it.
    Let me know your findings please to move ahead.

Good day!!!

6 blinks its the clear indication that you have bad power supply board..


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Tv won't turn on...light flashes red 6 times


According to Sony's diagnostic chart, a six blink code means the plus/minus 17 volt line is not being supplied from the G1 board. (The Power Supply). I would replace the G1 board and that should fix your problem.
I hope this helps,

the g1 board is your issue. 6 blinks means there is no or low b+ coming from the g1 board.
