Yes, the red picture tube has what is called a cathode to heater short. The only solution is to replace the tube. Problem is that it is no longer availible. There is a solution however. The tube can be pulled and sent off for rebuild to a company called Video Display. They do good work but this repair is expensive. Usually running around $400 to $500.

Heater-to-cathode shorts come and go like throwing a switch when they occur. If this comes on gradually as the set warms up, then there is a problem with the drive circuits or the screen (G2) voltage. That is a much less expensive repair.

I have a sony kp-51ws510 projection tv, i replaced the convergence ic's and a pico fuse and then reset the convergence. The tv looks good except for a green shadow on lettering, also on the convergence...


Did you check the two pico fuses on the G board? Usually at least one will blow when the original ICs failed. I am attaching a pic that shows the 2 pico fuses on the G board.

Sony kp 51ws510 upgrade to HD - how to do this


There are inputs on the back of the set. If your tv is Sony 51ws510 then it is capable of HD, but you have to have component or DVI cables to connect the tv to the HD device (HD cable box or DVD player).
<br>

<br>
On your set the component inputs on the back of the tv are video5 and video6 in the middle located in a vertical line (red, green, blue rca video connections with red and white rca audio connections).
<br>

<br>
You also have a DVI input toward at the top of the input panel (white connector with red and white rca audio connectors).

My sony 51" model KP-51WS510 flahes red 6 times when turning on.


Six flashes of the Red Stand By Light means the +5V line is probably shorted on the A or B board. Could also be an overload. Replacement boards can be ordered here: http://servicemanuals.vstore.ca/

you need a green CRT thats whay you have the white kind of concave lines with the green screen. You can try adjusting the green screen control but you need anew CRT ( tube) the speaker cover has two plastic plugs that get removed on the lower edge os the grille which covers the two screws that hold the grille on. If you need more assistancr or where to get a green CRT let me know as I have a link that has some green and red Tubes for your model.
