9 blinks error is for zero crossing error
your problem is 2 diodes on the G board that are leaking

D6116 8-719-074-43
D6301 6-500-567-21

One of these is surface mounted u will need a guy with soldering skills to replace it without damaging the board

Sony Wega kp46wt520 no power up, 9 times it blinks red


You will need to replace the G board. You can try replacing the two diodes that usually fail, But because its a complex circuit with the zero cross detection the diode replacement never fixes the issue. Replacing or remanufacturing the G board is the only sure way to fix that issue.

57 "SONY, DOES NOT TURN ON BUT STAND BY LIGHTS BLINKS 9X, THEN STARTS OVER


Hello,
I dont think your unit has big problem.
1. 9X blinks means 9 VDC supply is shorted either in A or B board.
2. IC708 is faulty in A-board
3.PS701 or PS702 is opened in A-board.

Dont forget to Rate!

Good Luck

Sony KP46WT520 blinks three times


They are on the main power supply board. Yes if you can solder and are careful around the high voltage items such as T60s you should be able to do the repairs easily. I would recomend a service manual however. If you would like a link to get the service manual and parts let me know
