You have convergence output failure. The output ICs will need to be replaced and possibly a small component like a resistor or two as well. Expect to pay a service company $350-$450 to resolve this.

Blue Convergence on Toshiba 42H82 42-Inch


it should just need new STK392-110 ICs which is actually not very difficult. You will need two ICs both STK392-110 and you can get replacements at the following link and they provide instructions on how to remove and replace Convergence ICs.
Heres the link.
