Quoting Jack O'Neill from the famous SG1:
"Well, this was an intergalatic waste of time..."

Yes, upper buffer is bad.

You need to replace the IC on it (about $5 each) or the entire board (pricey & hard to get.)

You also need to replace the 88N30W FET on the upper most heatsink of the Y-main, closest to buffers.

Tieny's thread is a good place to look as he had the same issue.
