Default PS4 Not Reading Disks

Got a issue with my ps4 where it isnt reading disks, makes a whinny noise like it constantly accelerating and slowing down over and over again.

Anyhow i originally replaced the laser, no good.

Thought it might be maybe the motor in the drive so just replaced the entire laser deck.

Still no luck doing the same thing.

PS4 is the newer CUH-12xx model.

Any suggestion would be welcome, before i throw anymore money at it!

so you replaced the entire sled assembly & frame?
all that leaves is the pcb isnt it?
unless there is a problem with one of the rubber shock-mounts putting it at an angle.

Yes the metal frame and sled assembly, this

Mines the newer model drive that doesnt have a PCB. Could it be the PSU not supplying enough juice?

It does read and recognise disks to a certain stage, but when you try to play the game it give the unrecognised disk error.

Yea it is a bit new for that, watched a video and the guy was saying itís this

https://m.ebay.co.uk/itm/For-Sony-PS...72.m2749.l2649

That causes the issue. Another motor in it, might be it as the whining noise sound like a motor struggling.

If you still have this drive: make sure all the cables are reconnected to the drive (internally and externally). Otherwise, the drive revs up and down.

With regards to the solder blob: depends on when/whom you purchase them from. I've purchased lasers from 2-3 different eBay sellers, but sometimes they have it, sometimes they don't... can you post pics?
