Hi Jeff and welcome to JustAnswer,
Thank you for the question and your patience. Should you still need assistance for information purposes only...
Initially, if the RESET was not corrective, then it would be indicative of an internal hardware issue.
Similarly, if all external settings & configurations have been re-checked with all connections & wiring correctly in-place, then the Pioneer should work as expected.
With the above in mind and more particularly the description of "...got sound...switched...to AUTO/DIRECT..." would point to the DSP (digital signal processor) circuitry in the Audio Assy Board P/N 7028071641060-IL as the most likely suspect. Going DIRECT would mean that the DSP is bypassed.
In most instances, this would require a board replacement rather than component level repair.
It would be to your advantage to evaluate other options considering cost of repair, down time, cost of shipping, age, parts availability and comparable prices of newer/better models; replace rather than repair.
I realize that the above information may perhaps be not what was expected. Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.
