Duncan,
I think you misunderstood me. It worked at first in the docking station. The I tried the Radio Shack 9V, and it charred the motherboard. I believe I tore the ribbon cable when I opened it to see what had happened. The ribbon I assume was intact before I opened it.
Today I fixed my (OK, it's technically my little brothers', through a long and boring story...) D-141, after dropping it onto hard ground off about a 6 foot pole. After it's landing, I attempted to play a disc, and my first clue that something was wrong was that it wasn't showing the total tracks/minutes when it first read it. Then, it got onto Track 00, and sat there reading the disc over, and over, and over. Eventually it would play if you manually moved it to Track 01, but it took about 30 seconds. I read this Sticky and another repair thread mentioned in it, and took mine apart. There are three pots in there, each with an orangish-yellowish screw.

Laid out something like that on the board, with the LCD facing you. The one on the upper left, *do not touch*. I haven't the slighest clue what it does, but the disc refuses to play unless it's in a precise position (slightly left of center, I believe)
The one on the lower right seems to control rotational speed. I attempted slowing it down, with the idea that it might improve battery life, but it didn't seem to slow it down much unless it was on the extreme right, in which case it wouldn't read.
The one in the middle is the one you want. I assume this has something to do with the tracking mechanism. Normally, it's slightly left of center. If you turn it to the right, it constantly skips, even if sitting still. I cranked it all the way to the left, and it improved it's skip resistance some. More importantly, it greatly decreases the time to recover from a skip. Before it would take about 2 seconds from a bump. Now, maybe 1/10 of a second.
Hope this is of help to someone.

EDIT: Had to add "_" to move + to neccesary positions.

question
My d-777 works fine on short CDs (under 60 min) but makes has some problems (squeaking noises) on longer ones. What up? A piece of dirt on the laser tracking mechanism?
You could well be right, there could be some debris on the worm gear... else, with a CD on the spindle, if you free-wheel the CD does it rotate completely on the level? I know of a couple of Discmen where the CD holding assembly was damaged, and that made it harder for the lens to read the CD at the outer limits of the CD because the disc kept moving up and down...
...worth a quick investigation?

The CD player in my car skips like an exciter little girl. I'm guessing that it's a tracking problem. It's a Blaupunkt. Does anyone have any advice as to how to adjust the tracking on it? Same 5 pots as mentioned in that other thread? Thanks!
How much is enough when lubricating the worm gear?
Also when cleaning the gear I can only manage to clear up until you're restricted by the lens assembly.
How do I clean beyond that?
Thanks

after so much lurking and reading DIY tips (esp. this thread), I've finally restored my beloved d350. It took 3 sleepless nights of trial and error (mainly pots 502,503,505 & 504..don't know but it worked).. And last nite.. my beloved d350 after 8 or 9 years in coma, it finally joins the company of my 4 d777, d915, 2dej01...and now i'm looking forward to a d303 in a few days..
yepey!!!.. (but i've got only 2 ears to listen to....)
