It is a bit unusual, but yes, likely an IC. Some problems go back to the convergence generator, but the first step is to change the IC if you cannot adjust it.

If you have normal range of adjustment in all three colors, you may have corrupt data. The only way to resolve that is to start from scratch, align the green geometry, and match the red and blue to the green.

If it shuts off it should give a different error code. My first guess would be that you cracked another connection, blew the output amp, and a fuse in the PS opened. This would give you a 2-2 error, however. Perhaps you have a problem with the front panel control switches. Try unplugging the control panel and turn it on with the remote.
