Onkyo TX-8050 repair: Part 1
We recently had a customer send in an Onkyo receiver with a reported problem of no audio:
This model is a great general purpose receiver for home audio. With 4x 80W channels, it was originally released in 2011 and has a clean sleek look.

This receiver came with a known problematic Texas Instruments chip which was recalled from the manufacturer, so the failure is not a surprise at all.
