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. In this video we test the unit, and start with diagnostics. After initial testing, we found that the DSP (Digital Signal Processor) chip has failed. 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.

We use a hot air rework station to reflow the DSP integrated circuit, and confirm this fixes the issue. While its exciting to see immediate fixed results, reflowing the IC is only a temporary fix. We have ordered the IC and will cover replacement in a future video. For now, check out part 1:
