John's SE #1 Rebuild
Posted by: Johnnya101 on 2019-01-27 09:23:04 Well folks, time for another rebuild thread. Purchased this fine SE in that huge lot I posted about. Absolutely disgusting. Covered in spider webs, grime, sticker residue, major burn in, dead bugs inside, dusty, stains, yellowed, etc. It's an SE 800k 1MB 20SC... Originally. Upgraded to a 160 MB quantum drive (still works great suprisingly! Was it the quantums that are good quality?) And 4MB ram! No maxell bomb in this one. Swapped out the battery. Did a smoke test. Bonged. Nothing on the screen. Then, suddenly, the whole thing was gray. Stayed that ways for a minute. Of course, now I know since it has lots of ram, that was the memory test. Whoever had it last adjusted the desktop to take up the entire screen. Got to order some tools to adjust it back now... Looks like a medium to high hour unit. Floppy drive inject won't work so couldn't test it (hmmm... Wonder who will have spares... Oh, that's right. 😛 ). First of the SE restore series I'll be doing with all of my new SEs. Some before photos... (Case not fully installed . Removed and checked some stuff and didn't bother screwing it back on)
Posted by: LaPorta on 2019-01-27 10:47:19 I got a good set of adjustment tools off Amazon a few months back...I’ll look up the link.
Posted by: Johnnya101 on 2019-01-27 11:37:06 That's fine, I found a few sets on eBay I've been wanting to order. Now I have a reason to get them.

Posted by: Johnnya101 on 2019-01-27 12:03:24 These are the ones I was thinking of https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F113539981612 Can anyone confirm these will work? I would think they are all about the same thing.
Posted by: LaPorta on 2019-01-27 12:04:03 Yeah, those will indeed work.
Posted by: Crutch on 2019-01-27 12:35:25 I have found a whittled-down carryout chopstick (small end) works extremely well... 🙂
Posted by: SE30_Neal on 2019-01-27 12:48:53 Great i know what i need now cheers
Posted by: Johnnya101 on 2019-02-03 07:13:11 Turned it on today to attempt to adjust the screen. Had the case off to adjust. Turned it on. Was greeted with a checkerboard. Turned it off, unplugged the hard drive (SO LOUD without the case) and turned it on. This time it booted to the ?. I was able to successfully adjust to the correct height, however, I just ruined my plastic screwdrivers trying to adjust the height screw. Looking from the inside side of the analog board, the height pot can only rotate around 260 degrees before hitting a solder joint. The height adjustment is all the way right, and still reaches the border. ??? Also, somewhat worrying find: With the case off and my ear close to the flyback, I hear a sizzling or crackling sound. Video is not affected, it's stable. Ideas? Is that normal for a flyback? No whining, just a faint sizzling when within a few inches of it and the case off.
Posted by: SE30_Neal on 2019-02-03 11:40:41 Mine sizzles and crackles as well Jonny. I’m not sure if that’s normal though i thought of resoldering the flyback this year just encase .Neal
Posted by: Johnnya101 on 2019-02-03 11:48:06 Might be due to the dust (In my case). Its covered in a thick layer of greasy dust. I put my ear next to my SE/30 flyback when I was adjusting that today and there was no noise. Just listed this one for sale in my for sale thread. Ive already got a few computers in various states of repair, and have decided I dont need another. Need to sell some stuff to save up for that clear case for my SE/30!
Posted by: SE30_Neal on 2019-02-03 11:52:46 Haha I really want the case too, if my wife gets a job soon then yes bring it on i’ll get one otherwise my money is just paying mortgage 🙁 we’ve only just relocated so not ideal timing. I do have a cd300i with caddy I’m thinking of selling and 1400 macbook. If that got me enough for the case that would be awesome
Posted by: LaPorta on 2019-02-03 13:28:11 As for a stuck potentiometer: you can try using a metal screwdriver with the power off, unplugged, and anode cap discharged. If it is still stuck, some of your favorite anti-freeze compound might help. I forget the way that the SE's look, but also, for instance, on a Plus, the hole accessible from the outside surface with plastic set was unmovable; I then tried it from the other side and it moved freely.
Posted by: Johnnya101 on 2019-02-03 13:43:27 I think I was just turning it the wrong way :O WHile I was adjusting my SE/30, I noticed that turning the way the AB says to turn it to make it wider, made it smaller. So I think its all opposite and I reached the end of vertical adjustment.
Posted by: Johnnya101 on 2019-02-04 07:04:38 No bites yet so I suppose I'll just rebuild it like planned in the meantime. Stay tuned.
Posted by: Johnnya101 on 2019-02-04 08:05:10 Mission success. Screen correctly adjusted to fit burn in. I see that its ever so slightly rotated, however, the video fits the burn ins rotation so I suppose I will leave it there. For your viewing pleasure. Ive narrowed down where the hiss is coming from: the anode cap. Does that mean dust and moisture, or a more serious issue? It is coated in a thick layer of greasy dust under the cover. Everything is gray from being coated in it.
Posted by: SE30_Neal on 2019-02-04 11:01:19 Mine Isn’t straight either although no burn in at all which is great
Posted by: SE30_Neal on 2019-02-04 11:02:47 Did those plastic screwdrivers work in the end?
Posted by: PotatoFi on 2019-02-04 11:09:20 How difficult/dangerous is it to correct a crooked screen? Mine is slightly crooked, but I'm a bit afraid to go after that problem for fear of damaging the machine or my body.
