One of the case screws on My SE/30 is no longer biting and just goes round and round.  Has anyone got a solution for this?

Whilst waiting for my UF8s to arrive for the board with no V-Sync I cracked open my (mostly) working SE/30 and pulled out the logic board for its recap.  This is my second attempt. It mostly went a lot smoother this time all the can capacitors off with no damaged pads using a cheap hot air...

I took a look at the board today and reflowed the solder on UF8 and UE8.  Still no joy! I am waiting for a delivery from Mouser with replacement UE8s and UF8s so when that arrives I will swap out UF8 and see if that helps.

no i turned the brightness well down - read warnings of burn in

If I were to decide to replace UE8 which I understand is a 74LS166 Which of the following 2 mouser parts should I be looking at: 595-SN74LS166ADR 595-SN74LS166ANSR Both are SMD, I think not sure what the difference is?

Board is re-capped (plus a trace repair to one I damage removing C2).  Scrubbed, IPA soaked and dried. Unfortunately I am still looking at a horizontal line.  I know its board related as another board works fine in this chassis.  I am off to do some reading about UE8 as a potential cause and...

So its all back together after the recap and the IPA soak.  I switched on got the chime and I can hear the had disk booting but I have still just got a single line display! I know the chassis is good - I've connected another SE/30 board and it displays fine, this board exhibits the same problem...

So the last few parts turn up and I made some progress. This is my second ever trace repair, first one on a mac.  Its just above C2 on the left: The whole board is now having a well earned bath in IPA after a good scrub down with an anti-static brush: I'll let it soak overnight then dry...

Am in the process of doing the recap but I broke a trace (see my recap post).  Have the wire for a repair but waiting for Amazon to deliver some solder mask, am going to practice my trace repair on a prototype board from another project before I move on to the mac logic board. Washing up bowl...

is the cable for an SE/30 - I am looking to build one of these and replace the logic board connector.  Do you have a part reference for the connectors?

So almost finished the recap today MOSTLY went well BUT looking at the photos above I think I damaged a trace when desoldering C2 - you can see it in the above photos.  I have some thin wire and solder mask on order so I will need to fix the trace before I can replace C2.  Fixing traces is well...

My Mouser order turned up today so I have started on my first ever recap on the newest SE/30 with the vertical scan problem. So far I have removed all the caps, cleaned up the pads, cleared the holes, and done and initial swab down of the board with IPA. Here is the board: And some close up...

Just pulled the drives out of my working SE/30 and noticed that the HDD bracket has an LED at the front that does not seem to be connected to anything: I am assuming their should be a connection between this LED and the HDD, looking at the HDD itself I can see what I think is an LED jumper...

Opened up my other SE30 project today and discovered a Shiva Etherport SE30 card with a Shiva Access-T daughter card.  It looks to be in excellent condition with a D-Connector and what looks like a 10-BaseT connector.  Not done any testing yet - recap comes 1st ofc. Here is the card: and...

So after 2 days of messing with this thing I have decided to give up and turn it into a fish tank of something.... Ok calm down I am, of course, joking :-) I just did what I should probably done in the first place and dug out my EXISTING Mac SE/30 and tried some strategic swapping of...

I don't have access to a scope.   I'll start with the recap.  For cleaning what's the best approach in the absence of an ultrasonic cleaner?  I have access to IPA and swabs and a toothbrush.  I've read comments about using a dishwasher but that sounds scary!  I've looked at cheap 10L...

Recap is planned, but I would like to see the display working first - and yes there is a thread in the classic forums...

Adjusted the cutoff and desoldered J1, Flyback, C15 and L1 now I have a horizontal line.  Its a start but not sure where to go next? Thanks to everyone for suggestions.  Will post some more photos later.

So it turns out the CRT is not dead - thanks for all the pointers here.  I adjusted the cutoff and re-soldered J1 C15 and L1 and I have signs of life - I now have a horizontal line. I've read the docs on this one and have continuity checked J4 through to the logic board connector - that's OK...

See above - good point, there is also a low quality startup vid.
