Home Theater Questions? Ask a Technician for Answers ASAP
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, have you tried a RESET of the Pioneer VSX-01TXH ?
Thank you for allowing me time to compose my reply.
I understand and presumably the user's method. Did the display showed "RESET?"
There is a technician's RESET but may and can cause (further) damage where the faulty part may overheat. Would you be comfortable giving this a try?
This is both an attempt of a fix and as a test by "brute" bypass.
Please click HERE.
All others would point to an internal hardware issue.
If the above is not corrective, please confirm that you are considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even a soldering iron?
Equally important, could you make use of the repair/Service Manual or at the very least, the schematic diagrams?
I can provide both the Service manual and the schematics should reference to it may be needed.
Were you able to try the Bypass Mode?
Please post back with an update upon try of the Release (bypass) Mode (technician's reset).
Additionally, re-check/re-tighten the screws at the rear of the unit. These and the rear panel serve as the common GND BUS of a number of circuits.
