O.K. Have a seat for this one.... I am hoping it is simple but with my luck
I have this detailed as much as possible and I hope you all understand what is going on.
I have a SCPH-3001R (v4). I hardly used it except for the first year and it sat for a few years on a shelf after a home move. I found it and started playing again. After about two months I bought a Crystal Chip 2.0 SLE. I was installing my CC 2.0 SLE one night and to make the story short, I was spooked and solder dropped onto the small DVD control chip pins. (CXP 102064) when I was almost done. So I could not remove the solder from the tiny pins and ordered a replacement v4 motherboard from richspsxparts. I told them what I had but what came in was a v4 motherboard that was a bit older (scph-3001 with older DVD version - not a big deal). It was dirty and the metal casing actually had corrosion along the edges of it. I used my own metal casing from my motherboard and tried it out. It appeared to work just fine. My daughter played her new (DVD) Barbie game for many hours on Saturday and a few hours on Sunday. It worked with all disk except my DVD remote setup disk (blue). I decided to let someone else (someone here on this forum) do my modchip install as I was already frustrated.
I was told by the modchip installer that my laser had trouble reading DVD backups and that he adjusted the DVD pot. The problem now is that it will not read over half of my DVD games. I put the DVD pot back to the original position and it was worse. I put it back to the 'adjusted position and it had more trouble with DVDs over the course of a day. OK that happens... lasers die right? I even tried to adjust with an O-scope but the DVD would never give me any kind of useable clean signal.
I ordered a replacement 400Q laser from richspsxparts. While waiting I fooled around with setting up a hard drive with the crystal chip (I had v34/BM on it). During this time once I could not get the system to load the boot manager. It would only come up with the Sony browser??? I do not remember what finally allowed me to go back to the boot manager (BM). I continued with the hard drive setup until the laser came in.
The new 400Q laser came in and I installed it Thursday night on an ESD station and took some photos to document the laser change. I was surprised/shocked to see that the static solder joint on the laser was already removed. . The bushings where the rod goes through looked clean/unused. Maybe richspsxparts does that as a 'service'? I replace the laser with no physical problems.
I power on the unit and I get the Sony browser??? I turned the unit off and back on and the same thing - no Boot Manager. Ok I tried a ps2 DVD and it does the same thing as my old laser does. [BTW my old laser reads CD and not DVD. The DVDs will spin excessively fast and the laser lens will bob up and down until it hits a disk read error.]. I try a CD and it does not read that also! I put back in my old laser and same thing...no DVD and no CD and no boot manager. This time I hit the reset 6 times to 'turn off CC' and the CDs now load when I disable the CC. I put in the new laser again and the CD will only load when I disable the CC. After many resets and power offs I was able to read a firmware 34 CD. I flashed the CC and reinstalled BM. I was now getting BM again every time I turned on the console. This is the second time in a week that I lost Boot Manager.
So... I can put in either laser (old 400B or new 400Q) and they both act the exact same. CD = fine. DVD = excessive spin and laser eye will go up and down. I have a lot of variables here.
1. Bad MB from richspsxparts (one of those DVD control chips BA/LA maybe?)
2. Bad CC 2.0 SLE (doubtful but at this point lost BM 2x for no reason)
3. Bad professional install on chip (loose wire, wrong location affecting DVD? Installer has a great reputation and CLEAN good looking work)
4. Bad original laser (lightly used but worked flawless before I wanted a mod-chip [I know things happen thou]) AND bad replacement 400Q laser.
Oh I also have the numbers on the new laser and I decided NOT to touch the pot settings until I get an idea on how to resolve this. BTW I have my guts in a new clear case and that was modified so I can change the pots without disassembly. I also soldered a ground wire and a signal point wire for o-scope testing. I even have a small hole to change the white cog wheel to try that (original position is marked).
Old laser was within specs as far as the pots go. I can get a clean o-scope reading for the CD (about 640 mV Vpp) but not for the DVD (looks 'noisy' and small - no matter the adjustment).
New laser pots:
DVD= 657 (is it me or do these seem a bit on the low side even for a replacement non-Sony laser)
O-scope readings for the CD are only about 320mV and the signal is not clean/clear. DVD values again are small and worthless.
UPDATE: while taking the reading for the CD side I noticed that my Final Fantasy VII CD (original disk) will no longer load on the new laser. It will see the black bottom in boot manager but it will not load and will eventually stop spinning. A ps1 back-up would not work either. Only ps2 game that would work is Crazy Taxi (CD based). FF VII is what I used to test the CD side before. So maybe I am leaning towards a bad 'new' laser.
So please let me know what you all would do? I can always send the unit to richspsxparts and let them determine if it is a bad laser or motherboard (both came from them but I did have a CC SLE installed). It would seem like a waste because to replace the laser seems so easy. Would a modchip problem cause a problem like this? Could the BA/LA chips be suspect (version 4)(BA/LA Symptoms)? Any other testing that I could do with what I have to narrow down the list of possibilities?
Am I asking too many questions?
