The UE22 appeared because one or both DSP chips have failed, or have lost their power supply voltage. Attempting to update the firmware corrupts the flash memory and the UE22 goes away, so now you have two problems. I have seen this happen on my SC-LX56, 86 and VSX-LX55.

Instead of trying to navigate the schematic diagram you may find the power block diagram easier first. That shows the 3 voltage regulators you need to check on Page 19 of the manual RRV4617. Once you find those on the schematic, locate the big capacitors on their output.
