What about my ps4 going on x?

Sa

Have a normal ps4. The problem is she does not show me a picture anymore and always turns off automatically. Say she goes from now on the same. The problem with the picture I have managed once last time to fix. I went into the safe menu and set something as it was on the Internet. After that, the ps4 had issued as usual again for no reason and since then I can only turn on briefly and get no more picture. I can't get into the safe menu anymore. (vllt because they generally can't stay much longer?)

I have also just screwed and completely removed from the dust. So also the fan and the hard drive, etc. So everything.

The ps4 still turns on, but shows no picture as usual and turns off quickly.

So what else can I do? What does the playstation have and how can I repair it or how expensive is the repair?

I do not want to buy a new one because soon the ps5 comes out and I only need it for a game.

Ho

Turn off Ps4

turn off the TV (completely, unplug the plug)

turn on the Ps4

turn on the television

it helped me try it out.

You have to do it exactly in that order
