I have a toshiba 57hdx82 got it in 04 replaced the scan converter in 07 and now almost 2011 the set is giving me a convergence error the red and blue crosshairs are fine cant get the green to go straight...


It sounds like it has cost you a fair bit of money over the years. It would be great to get it going again but if you stand back and look at what it may cost, would it not be wiser to put your money into some more modern technology?
Convergeance errors are unlikely to be easy fixes. I expect the power supply is getting noisy and producing distortion on your picture. Replacing the many aged capacitors will possibly repair it.
Hope that helps.
