I just replaced the convergence IC's with 150's but my red convergence doesn't align. When you go to the convergence menu, the red line is off to the right by a good couple inches and I cannot bring it over to where it needs to be, nor can I adjust the other colors over to it. What is the deal?

The red convergence IC has failed. There are I believe 3 total convergence IC in your tv. The prefix for all three is STK392-xxx. If you can solder you can try and replace yourself otherwise you need a tv tech. With Hitachi's sometimes some critical resistors will change value as well and have to be replaced with exact equivalents. Sorry wish it was an easy solution..
Yes, it could be from the convergence amp having a loose connection. Big Screen tv's have problems with loose connection especially when moved or bumped. If you can take back off and find convergence amps then safely tap on ic's and see if it changes picture then it's maybe just aloose conn. If no change then you need to check resistors inline to red. At the most replace IC's these are the large STK's by a heatsink. Hope this helps!
Your convergence ICs are bad. They are about 20 pin chips located on the D board. They are on the largest heatsinks on the board. Check the resistors and fuses underneath or next to the heatsinks with an ohm meter to make sure all are good as they can fail with the ICs. This is a difficult repair but can be handled by a moderately skilled electronics tech. After all bad parts are replaced, run the magic focus to hopefully re-align the colors. If you have to go into service mode to re-align convergence data, the complexity of the repair just went up another notch. On a sony, service mode is tricky and a service manual would be highly recommended. Your tv uses two stk392-150 ICs (ic 1502 and ic 1505)
