Did you replace the convergence board or the convergence power supply board? usually one color will be a problem with the convergence board and more than one color means the convergence power supply is the problem. Ebay isnt a good place for boards as you never know if the board is good. You can get the convergence or the convergence power supply boards at the following link along with free shipping and tech support.

I had the same problem, I resoldered the fyback (LL008) and changed the fuse (FL231) had my voltage back, but still no convergence. I read in the service manual that disconnecting BW001 BW002 on the Converagence Amplifier board may remove the load on the Convergence Power Supply. I unpluged the TV did remove it and turned the TV on, let it boot up and run for two minutes or more, then shut it down, waited a few minutes. Unpluged TV and I pluged back in BW001 and BW002 connector back in and turned the TV back on and it was back. Some adjustment and had had a great picture back. If this done do it your out of luck, the Convergence Power Supply and Convergence Amplifer Boards are no longer avialable. Make sure that all the flyback leads are resoldered real good.

OK on same circuit board as fuse up on the front part of board look at capacitor cp150 if it is swollen or puffed up it is bad 2200uf 16v use 25v and replace 2 other capacitors in same area cp114 cp120 220uf 35v.
