Sony kp-51ws510 tv blinking light 6 flashes on timer/standby

this model did have problems with bad picture tubes---screen goes bright red,green,blue and set shuts down.

set also does this to protect itself---when fails look to see if specific sequence of blinks

Standby flashing light shows that tv got some internal problem. How many times standby light is flashing is info that provide info about what section of tv got problem.
Count standby light blinks and let me know, there would be 3 seconds long pause in blinks so count pause to pause.

B+ current shrted. Repalce the D board you can get a replacement D board at www.tvrepairworld.com

is there a cadence to the blinking timer light?

Please count standby light blinks and let me know.
There would be pause of 3 seconds in blinks.
Also confirm is it Sony KP-57HW40 model?

Plugged in TV. Timer Standby Light just flashes continusly. No Picture and No Sound.

eight blinks means, "High-voltage error" and the probable cause location listed is, "T8005 is faulty (D board)". T8005 is the fly-back transformer assembly.

* Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some newer models of Sony TV sets, this code means that T8005 is defective on the D board. That would be the fly back transformer and the horizontal output transistor.

The power supply or sweep power supply blew up, or the Horizontal/high voltage circuit went bad. If you have no tV repair experience, call in a pro to assist you in this repair. Good Luck
