not reading

So my Super slim PS3 is not reading games, it can read DVDs and CDs just fine, everytime i put a disc in the consoles, it tries to read about 3 times without success before it just stops trying, just replaced the laser, still the same issue, i tried resetting the system, rebuilding system files...

Ok so here's everything I've tried so far and what symptoms I'm getting: I was having MAJOR trouble getting my scph-77001 to read any kind of disc, getting a successful read roughly 1/25-30 tries/boots. Tried adjusting pots in ~25Ω increments, both up and down in regards to the stated factory...
