KP-57WS500 8 blinks will not power on

Hi,
I can help you to solve your Sony tv problem.
Is it Sony KP-51HW40 tv or any other model?
How many times red light start blinking after three seconds long pause?
Let me know to proceed, can you check voltages with multimeter in tv circuit board?
Thanks.

power light if it shuts down should blink a error code--count the blinks and a pause?


SD TECH

Check fuses on power/delection board. Besides normal looking fuses there are micro fuses that are small and are yellow or blue in colour

High voltage in TV got problem and thats why TV gives 10 time blink error code.
Qualified TV tech will fix it as its bit complicated fix.

Go to this link and scroll down for info of the ten blinks.

There will be around 8 fuses . Four will be in and around and another four will be around main board . Did you count number of times the light blinks so that the problem can be easily diagnosed .

Ok I solved my own problem and posted the results here,

Hello,
Please mention how many times standby light blinks on your KP-57WS520
There would be bit long pause between blinks so count the blinks and let me know to help you.

KP46WT510 Shutdown 6 Blinks. 6 Blinks = Low B+ OCP/OVP
SOLUTION: Replaced Flyback transformer. It had no rings on the ringer test.
HQ
Comments: Any load on the B+ line can cause 6 Blinks.
Example: If the 200v line is loaded down will cause a drop in B+ due to bright picture current demand.

6 blinks means lamp thermal fuse blowing, replace thermal fuse.
