    Hello, if it's a bright blue it may have a bad crt socket panel or a shorted blue crt, not an uncommon problem with these sets. If it is a crt issue the crt panel can be removed carefully off the blue crt, make sure it isn't touching anything, then power the set up and see if it stays on, it just won't have any blue. If it does, it either has a bad crt or a bad blue crt socket panel.....tks....Terry

Have sony kp51ws500 won't turn on, it clicks then shuts down and i get 7 blinks on front--had green, blue, and red line issues before

Hi wright
To answer your question;
The 7 blinks code(sony error codes) means that the horizontal deflection has stopped.
The common cause for this are transistors Q8035,Q8038 and the horizontal output Q8024 all located on "D" board.
Hope this help and let me know if you need further assistance.

My 3200 has shut down and needs to be rebooted. I tried the recovery disk- 1-3. It states that there was a recovery failure. M.Wright

Your problem here is more then likely a hard drive issues due to bad sectors. Back up information and replace hard drive.

What do i do with the third wire

You do need a neutral for a timer switch, that is the white wire coming off the timer. The black wire is for the hot wire coming into the box, and the blue wire is the wire going to the light.
