It loads but doesn’t come on

Try holding Option key at power on, does it show boot choices?

Follow these steps, testing after each step:

• Mac Doesn't Turn On.
• Mac Startup Options.
• Mac Startup Methods.

If that didn’t help, then I recommend service.

Service Checklist:

• Mac service pricing.
• Check AppleCare Coverage.
• Get your Mac ready for service.
