9 blinks is a ZCD error code (zero crossing detection) which means it is a bad g board. I had the same problem with this tv and have yet to fix it cause you cant find the board you need anywhere and most suppliers have boards that they fix themselves which only work for a month or 2 and then die. but you need to replace Replace D6301 on "G" board and d6116, d6117 i use 1n4148 for the little smt diodes, d6301 nte116 should suffice
it will be those few diodes and 15-20 caps on the am board if you choose to fix it yourself. here is a manual that lays everything out for you if you choose to fix it yourself. click here for repair manual
if you need further assistance please let me know and i will be glad to assist you from there. thanks and good luck

I dont have a remote for my tv and it wont turn on manually the led light blinks 9 times and stops and starts again what should i do?


The blinking lights are a service code. You should first try to unplug your TV and leave it unplugged for at least 4 hours... then plug it back in again.

If the blinking light is still there and no picture, time to have the TV serviced. Good luck!

The tv wont turn on. the red light blinks 9 times.


There is a problem with one or two of the diodes on the G board.
Zero Crossing Detector 9 times 9:0 or 9:1
Probable cause • D6116 or D6301 is open (G Board)
symptom • No picture
I hope this helps and good luck!

Tv wont come on and a red light is blinking. I have a Sony Wide screen projection TV model kp-46wt520


Can you unplug the TV for about 15 seconds, and then plug back in and watch the stand-by light. Tell me how many time the stand-by light blinks in regular intervals. If it doesn't blink at all, you need to change a fuse on the g-board. Once this is done run back through the stand-by blink light process, and more troubleshooting can be done if problem isn't already solved. If the stand-by light just keeps blinking with a count over ten just tell me, and I'll look for other possibilities.

Tv wont turn on blinks 9 times then 1 time


I was inform that it could be a sensor (bad diode), you have to get a multimeter tester and test the diodes and if current flows from both sides then replace that diode.

Projection tv wont turn on


a sony should only blink up to 8 times. If its continuous without any pause that usually means No reply from the jungle (data bus is busy, shorted to ground or held
high), IK video path is defective.
Count your blinks again. let me know.
