Hi all,
I just got myself a dissasembled SCD-1 off of fleabay for around $730. I knew the risks that are associated but I figured I can levarage my SCD-777ES to fix this puppy.
So lo and behold it took me two nights and I was finally able to assemble the whole thing. It was missing a few screws and I had to resolder the wires going into the RCA ouput board (because they were ripped).
I also had to "fix" two of the ribbon cables that connect to the Transport Assembly. I cut them while opeing the box. One I was able to to trim the end of and the other had more damage so I eneded cutting the part and sanding down the plastic to expose the pins. I checked for continuity on the ribbon and looked fine. I added some scotchtape to the back of the ribbon to mimic the backing material that goes into the plug.
And that was all of the repairs I had to do.
TLDR:
After I assembled everything I checked all the connection and decided to power it up.
Upon power up I heard a mechanical noise of gears going back and forth and a second later I read "System ERR e001" on the screen 🙁
I was hoping for a "NO Stabilizer error" or a "TOC" error but with my luck there is NO information anywhere on this error!
When I removed the cover I saw the the noise was coming from the Tilt Mechanism on the Pickup and it was moving the pickup up and down quite notecably! I have never hurd this type of noise from my SCD-777ES
Only one person reported the same error after replacing the firmware chip on his motherboard :/

Has anyone else seen this before? Is the main board fried?
Is there a way to check if all my power supply oputputs are workign correctly without the motherboard plugged in?
Thanks!

I did something that I probably shouldn't have... I removed the cover on my SCD-777ES and swapped in the firmware chip with the one from the SCD-1. The player booted up and I was able to play a CD. It's version is the SCD-1 firmware is 2.4 and the 777 is 2.2.
However I could not play an SACD... got the No Disk message. I swapped the old chip back and I couldn't play an SACD as well 🙁
I think I have to perform the alignment procedure :/

TLDR (Too Long Don't Read)
I go ahead to do an Overall Adjustment. I initialized the data and had to power down to remove the cover in order to load disks needed for Overall Adjustment. I discover a piece of lint on the laser diode! SACD playback works again on my SCD-777ES!
long version:
So I started getting ready to perform an "Overall Adjustment".
So I pumch in the code in the remote control "to initialize data" (steps 1-2) and go ahead to insert the CD for adjustment and I can't open the tray!
Doh, they actually state to NEVER have the cover on when aligning the player. So I had to power it down, remove the cover, and bridge the two solder connections next to the cover connector.
So I go ahead and turn on the player to see how it works naked... and I notice something on one of the lenses... "gees, that a wierd looking diode with a wire inside of it... hmm, maybe I blow on it". Guess what! There is a piece of freaking lint! So I almost blew it inside one of the crevices of the laser, so I picked my ESD tweezers and carefully removed it. Lo and behold SACDs play again!
I am going to assume that the firmware chip from the SCD-1 was working and it was the piece of lint that was causing the No Disk on SACD. Dodged that one.

I am one very lucky guy today!
So I finally decided to sit down and test all of the I/O and Rails of the Connections on the Main Board. It looked like all the rails/voltages were proper and withing spec but there were some clocks missing and some weird voltages.
I did all of the connectors except for one of the ribbon cables when I noticed some physical damage on the board!
I noticed that IC703 (DSD Decoder Chip) had damage on two pins, as if someone had stabbed between them and pushed them aside. I took my multimeter to see if they are shorting with the adjacent pins but it didn't seem so. never the less I used my tweezers to ever so gently push them away from the adjacent pins and make sure that they are not touching anything.
Than I noticed damage on IC730 (Buffer). It looked as if someone just smashed it sideways so all the pins on one side were kind of laying on top of each other. It looked like pins 11-16 were touching/laying over each other and shorting. I checked them with the multimeter and they were shorting... but according to the schematic they all go to ground so I was good there. I checked the other pins to make sure they are not shorting and they were good. I poked a little with my sharp tweezers but nothing forcefully.
Than I noticed some smearing/damage on IC701 the CPU. I looked like about 4 pins on the IC were rubbed/pressed against something and there was some crap that could have been shorting them. So I took the multimeter again, checked if the are shorting or not but it was very difficult since they were so close. I took my sharp tweezers again and scraped between the pins to make sure that I break any shorts that might be happening. I tested with the multimeter again and it looked like they weren't shorting.
I inspected the board for more damage but didn't see any on the top side and decided to plug it and turn it on to see what happens. It was a sight to behold!!!!! I did not see "SYSTEM ERR e001"...... I saw "Unloading..."!!!!!
I powered down, installed the optical drive assembly, turned it on and there was no weird noise or movement from the laser... I put in an SACD and it read it like a champion!
To make this even sweeter, someone was selling an original SCD-1 remote and Stabilizer for $65!!! They came it today!
I hope this helps someone.
This error is definitely caused by a shorted or a dead IC on the main board. I was ready retrace the whole board and make sure there were no discontinuities. Than I would have started repopulating the board with new components... a very time consuming and tedious process.

Thank you very much for this info. If this ever happens to me I´ll know what to look for. Shortings on the main board (and evil lint!).
