Hi,

I am working with above Touch Bar macbook and when turn on, Apple logo appearing and progress bar goes for about 10-15 seconds, then screen goes off and fan works very fast. CPU is getting very hot too. Where should I check?
After few seconds again apple logo appear and goes it as a cycle.

Start with DFU revive/restore.

Any history available?

I didn't try DFU revive/restore since customer needs data badly. Any way to recover data first? Don't see any lifeboat port in this model.

No water damage or any other burn marks etc.

Also forget to mention that CPU is very fast when turning on.

Try Target Disk Mode to backup the data.

Revive option in DFU does NOT delete any data.
Restore wipes internal SSD.
