It could possibly be one of the regulators in the stand by circuits especially if the power light is not lit up. I would check the stan dy voltages and see if they are present. If you dont have the service manual you can get one emailed to you at the following link, and they provide free tech support to help you diagnose the problem when you purchase one of their manuals. Heres the link in case you dont have the manual.

You will have more then one fuse on this TV set. Check for the letter F follow by a number to find the rest of the fuses and test them all.

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.

check all the fuses especially the pico fuses on the D board as the led should at least light up if the fusese are all good, then the set should throw an error code when you try powering it up. Let me know if you need more assistance

KP-51HW40 - Picture not Clear


Your problem is a typical convergence problem that happens on almost every tube type projection TV set ever built. There are two Convergence amp IC's that need to be replaced. If you have no TV repair experience, play it safe and call in a pro to assist you in this. Good Luck
