So after someone forwarded' me this link I decided to try several different positions with my unit. I could not get it to Load (LOTR T.E. Triology disc 1 & 3. However, I can hear it both spinning and the slider on which both lasers sit, scanning back & forth. I take it that's NOT what you were hearing before...
But after trying different orientations to horizontal (including up to 90 degrees sideways It didn't alter the experience or playback and it was still UKNOWN - INVALID - Cannot playback this disc - Cannot Operate this disc.
So since my unit is a month off warranty & I have other BR players (now) I decided to crack open the unit and see if I could replicate your success. The design of the BDP-s560 reminds me of a 70's muscle car. PLENTY of room to work around in there. With the cover off, there are two screws and 4 vertical, 2 horizontal tabs holding the cover onto the top of the drive - and one cable that had to temporarily be unplugged as it stretches directly across & over that top cover for the drive. Got it off, gave a gentle dry air blow across the lenses as I could see just the tiniest amount of dust with my flashlight (made sure not to spit etc.).
Next I hooked the unit up to power and inserted a Blu-Ray disk that is known to work w/ this unit. Nothing happened (said No Disc) on the front. I pressed eject & then closed it up again with the Disc in. This time it started to spin and I could see the purplish color of the laser through the top of the disc. Somehow I thought it was going to be BLUE BLUE, as in NAVY BLUE. Anyway, it wouldn't play it would stop spinning and then give an almost immediate INVALID. ==> Which again is NOT what normally happens for many of us. For many of us, the Sony BR player is working hard for about a minute. Searching back & forth we can hear the mechanism that the lasers slide on very clearly (unlike the short search it maybe does for 5 seconds or less when it recognizes a Blu-ray) and begins to start in 15-30 seconds when it displays the menu or BDLive sequence.
I was getting panicky (i can never think right when my stuff starts going bad. I was wondering WHY isn't it playing is it like some of those old VCR's that have light sensors or switches in them? And they won't begin playback if the cover is off? Or is it that the cover which has the top part of the spindle mechanism that helps hold and grip the discs is not present so there isn't enough downward pressure to make the disc spin. I tried ever so lightly to apply a little downward pressure, but it would have taken something like a light weight washer to hold it in place? IDK HOW you were able to have it open & watch all this?!?
BUT here's what I can say after trying this experiment.
One there is NO ONE UNIVERSAL - UNKNOWN - INVALID - Cannot Operate This Disc - Cannot Playback this disc ===> Problem.
For some it comes directly & immediately after a firmware reflashing. This is what happened to my unit. Played 100% of the Blu-Rays I tried in it while on FW Ver ....08. Updated to Ver ....11 wirelessly (multiple mistakes there --> don't do it via the internet especially wirelessly and DON"T UPGRADE if you don't have a problem!!!). Anyway the update appeared completely successful, until I the next time I attempted to play Blu-Rays. From that point on the unit WOULD'T READ 60-70% of the Blu-Rays I tried including BR's that it had read just fine prior to the Firmware update. Still read 100% of DVDs.
Shipped my unit for $15 down to Laredo, TX to Sony's Repair center (under warranty). They re-flashed the firmware and returned it to me ---> no mention of anything else done to the unit and no repairs etc. listed on the invoice. That fixed MOST of the problem. However, since the repair, Three discs Two Brand new Rentals from Redbox (Limitless & X-Men: First Class) were UNKNOWN & The LOTR T.E. Trilogy BR's that came out well over a year ago discs 1 & 3 are Uknown. The first two I believe are DRM / new information that require an update to run. The discs all play fine on my Sony BDP-s370 but it has a much newer Firmware available & it's installed. Those that didn't install the latest firmware on the BDP-s370 reported a problem playing that X-MEN.
SO... for ME the issue was not a balance or centering issue. It was FIRMWARE.
OTHERS have reported that a dirty lens was their culprit and cleaning the lens restore it to reading those BR's. However, given that my unit is playing about 96% of the Blu-Rays since coming back from repair, I think I can rule that out as my small current problem. Not saying it's not the issue for some units. This is proving to be one frustrating thing!
