    I checked again on the number of blinks and had someone else check it and it is 6 blinks. Hope it is still a minor repair.

  • joandrsn Jul 04, 2008

    how much would the repair cost me?



  • joandrsn Jul 04, 2008

    So what you are telling me it will either be 300 or 200 to fix?

Very minor. Horizontal deflection is stopped Q8035 or Q8038 on the D board is defective. Change both just to be sure. If you need more assistance let me know.

    Thats alittle more involved as the +5 line is shorted or over loaded on either the A or B pc boards.

    A repair shop will most likely want to replace the A board first at about 300 if that doesnt do it then the b board at about 200. Most shops wont do component level troubleshooting on the A board. the b Board has no serviceable parts so that has to be replaced if the trouble is on that board

The Blue CRT has shorted and shutting the set down. You can verify this by simply sliding the Blue CRT drive board off the neck without unplugging any of its wires, Just let it hang suspended and then try powering up the set. If the set stays on you will know the Blue CRT needs replacement.

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.

Cant fix my sony KP-53S65

If the TV will not turn on and the red light blinks on the front of the set, it means that the microprocessor has detected a problem in the set and shut the set down. It then blinks the red light a certain number of times, and the number of blinks is the code for why the set has shut off. How many times does the red light blink before repeating?
