Unscrew the internal mainboard assemblies to expose the audio output power transistors clamped to the rear wall. Clean away old, flaky white thermal compound using a plastic scraping tool and electronics cleaner. Apply a thin, uniform layer of premium non-conductive carbon-based thermal compound to ensure efficient thermal transfer from the components to the aluminum body. Step 5: Address Component Code Errors ("Display Safe")
Overworking the laser makes the unit hot. Use a CD lens cleaner, or physically clean the laser lens with isopropyl alcohol.
