Last week I started a new repair project: a 42" Philips TV. The power supply was obviously defect, but I ran into another problem as well...
This unit sold from 2012-2015 as the top-of-the line AV Network Receiver from Denon. I got my hands on a unit with power protection issues. Here's the repair log the Denon AVR-4520.
Another lucky find: Rotel RB-970BX Power Amplifier with one defective channel. Let's fix this!
The venerable Marantz PM80 Mk2. This unit was completely dead, but I was able to bring it back to life!
A classic 1989 Denon PMA 720a Integrated Amp that made a bang and wont't turn on. Let's solve this!
A Marantz SR5200 receiver with a non-working front-right channel. Let's fix that!
