A “dead” retro console often isn’t dead. Here are safe checks to try first, the most common causes, and what a professional diagnosis involves.

Start with the simple checks

The power supply. Retro consoles use external adapters that are easy to mix up, and a plug that fits can still be the wrong voltage or polarity. Use the adapter made for that console, and compare the label on the adapter with the label on the console.
The outlet. Try a different outlet, and plug straight into the wall.
Power light versus picture. If the power LED lights but there’s no picture, the problem is usually the video cable, the TV input or the game, not power.
The cartridge. Dirty contacts can cause blank or blinking screens. Try a game you know works.
Switches and jacks. Power switches wear out, and DC jacks loosen over years of use.

Safety: don’t open a console while it’s plugged in, and don’t use a power supply that’s hot, swollen or damaged.

Common reasons a retro console won’t power on

Inspecting the outside for damage, missing screws, signs of liquid, and the condition of the jacks and ports.
Testing with a known-good power supply and cables to rule out accessories.
Opening the console and inspecting the board for burnt parts, corrosion, failed capacitors and earlier repair attempts.
Tracing power from the input through the fuse and regulator to the board, to find where it stops.
Explaining the problem to you before any repair work begins.
