Samsung Convergence Problem	Can't Post

Apparently this is a common problem, my HCN4226W shut off just after having convergence problem(s). Repairman came out, disconnected the power lead feeding the CG/AMP board and the tv came on with just the background screen. He said to replace the IC modules, STK392-040's $16 each, and it should fix it compared to his $270 estimate for him to do it. Replaced the IC's, no change in correcting the problem. Ordered a service manual from servicemanuals.net, $15.99, but it was very vague in the troubleshooting section. From another post that I read, I replaced the 2 caps on the board, still no help. Should I have just replaced the complete board, about $70 from vancebaldwin.com or does anyone have more suggestions on what I should check?

Did you ever find a fix? My HCN4226w did the same thing. There's lots of post about convergence problems but none of the post a remedy for when it wont turn on. Any help would be appreciated. Im prepared to buy the entire convergence board from samsung but I want to be sure this is the fix?

Replace the whole board assembly, $70 + shipping from VanceBaldwin.com. I tried the IC replacement but wasted $40 and time and worry. Still have a slight problem, but should be able to figure it out.
