FIXED - Pioneer Elite Receiver UE22 Error Fault Code

UE22 eror fault code on Pioneer Elite receiver is likely due to solder fatigue on the Texas Instruments DTS chip and not due to software update or corrupt firmware. I got lucky and simply fluxed and re-heated the DTS chip and the receiver seems to be working properly with no more error codes after more than 50 power-on initiations and a week&worth of usage. Be sure to check out these excellent videoS from another Tuber which shows thorough and very useful repair details: One Month UPDATE: Everything still working beautifully. To reduce further solder fatigue, I have added a heat sink to the DTS chip AND force cooling to the chip. I&experimenting with two different fans. One is a 5V fan plugged into the USB port on the back of the receiver which turns on and off with the receiver. Another is a 12V fan powered with a wall wart. The wall wart is plugged into a power strip. The receiver power switch is left in the ON position and both the receiver and the 12V fan are controlled by the on/off switch on the power strip.
