Sony KP-51WS500 FBT

Do you know how do you replace the FBT? I have the HV block on way, and IF the FBT isnt too difficuilt to replace I may look into that as well. I appreciate your time and input. Does it just press into place? or is there soldering involved? Fro the below picture it look like it may just stick into place.

KP-51WS500 Flashing 6 Times


Well, it's DEFINITELY the High Voltage power supply is DEAD! Won't start up...or goes into OVERVOLTAGE SHUTDOWN....

Most of the time it's overvoltage problems...

The KEY to knowing which one is actually occurring is the amount of time it takes before the 6 blinks occur...

A DEAD HV circuit takes a lot of time, while the OVERVOLTAGE will take less than 40 seconds for it to register the 6 blink code....

In this case (overvoltage) replacing the HV oscillator/regulator IC is mandatory...

A dead HV circuit could be anything in the HV circuit, from the Regulator IC to the HV splitter...
It's really wiser to consult a TV technician on this....

I have a sony kp-51ws500 that the red is bowed across the screen.


If you are referring to the convergence ICs (STKxxx), then look in the area for fuses and/or low valued resistors that may be open.

Let me know what you find.

Green Screen then off...8 blinks


According to service manual, 8 blinks is a high-voltage error. A link to the manual and a how-to guide for retrace lines is here: http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html
