Below is exploded view of your Sony KP-51HW40 TV rear side which shows board names and location.
You need to check D Board for convergence ICs and these are marked as IC8001 & IC8002 on circuit board.

Replace Both of your STKs convergence ICs they are big black ics they will have STK numbers on them STK392-560 ect. Parts you can order on line www.electronix.com or call 1-800-223-3205 you also need silicon heat sink white compound to put on back of new ICs. Use same # on stks but if they are 110s use 180s if 020s use040s.

Blinking 4 times - Sony KP 51HW40


Hello scramble5,

This might be a convergence amplifier problem or a problem in the convergence coils. I would suggest that you have a qualified TV technician check this TV out. This problem is usually due to the convergence amplifiers malfunctioning, to replace then the two modules and their biasing resistors must be replaced.

I hope this helps
Thank you,
