Its 2 times blink error code that shows +B volt supply (+135 volts) is shorted, most probably horizontal output transistor is shorted, replace it.
If you are good in soldering parts in circuit board then take out horizontal transistor, check it, found shorted then replace it with same number.

Horizontal output Transistor Q502 number is 2SD2578 and available in Part Store for $10
Let me know for further query, if any.
Thanks.

    ========================================================
    Yes, I have required board part number as follows..

    A1316498A... G BOARD COMPLETE (KP-61V90)
    Please search above board over internet for best price, if available because Tv is bit older model.

    Below is an image that shows location of G Board in TV.
    Thanks.

TV turns red,shuts off, stand-by light blinking 8Times


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 projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

Sony kp-51ws520 when turned on just has standby light flashing . the rest is all dead, no picture or voice.


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.

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

My Sony KP-46S25 TV is blinking red light and is not turning on, please advise.


Please update this with the blink count. The standby light shouldbe blinking a repeated count with a pause. This will indicate the problem circuit and allow me to provide you with the probable defective part(s).

Thanks,
Dan
