    LC TDK PSU issues

    Hi everyone, I have a TDK supply that has a really strong burning smell and gunk all over. I am going to send off for all the caps on the right side on Friday and give it a thorough clean. Just wondering if there is an issue with CR4 and what part it is, the smell seems to come from that part.

    Chip came off Classic II board and took a pad with it.

    Hi everyone, I was cleaning the Macintosh Classic II revision 1 logic board with a q-tip soaked in isopropyl alcohol and a chip I was cleaning came off the board, it read 136x 78l08a and I believe it is a texas instruments chip. I looked up the last part and it came up with voltage regulators...

    Macintosh LC very quiet speaker

    I ordered Würth electrolytic caps for the system, I do have aluminium polymer and tantalum for the LC475 but my surface mount soldering isn't too good with my setup at home, so I thought these caps would make it easier. I did purchase solder paste though, im going to try that out for the LC475...

    Macintosh LC very quiet speaker

    Hi everyone, just received an LC that has not been recapped or anything like that, appears to be all original. I replaced the leaky TDK supply with a working ASTEC one, cleaned the board, installed a new PRAM battery and system 7.1 onto the HDD. Everything seems good except when I set volume to...

    Macintosh Classic II

    Decided to delay all my projects to 14th of nov as I have exams now. I will probably end up going with tantalum.

    Macintosh Classic II

    This is what my plans are: - Wash then recap the logic board with normal radial electrolytic caps. - Recap analog board (already put fresh solder where it was needed and snipped JP1). - Fix the small crack. - Clean the fan, floppy drive and exterior.

    Macintosh Classic II

    Just received my Macintosh from the courier, it has a very small chip up the top left but everything else looks fine, it is 100-110v though so ill have to buy a step down converter. Logic board looks like it needs a wash and recap, removing the battery was a good start, its great that it didn't...

    Powerbook 145b corrosion repair

    I pulled more things from the laptop today, should I recap the TDK CXA-2010 screen power board? Should I replace the caps on the board next to the panel its self and could I wash that board?

    I did see a youtube video about the inverter recap, I guess I can take it in with me on Friday to get it cleaned properly and screen recapped.

    Powerbook 145b corrosion repair

    I got it working kind of, partially cleaned the board. I can move the mouse around but the screen flickers and has bad ghosting. Chimes too. HDD and floppy not doing anything. Photo is what it looks like currently.

    Powerbook 145b corrosion repair

    It did chime before and display a blank screen with a cursor, forgot to say. Ill wash it on Wednesday and report the results. My university has a classroom with facilities to bake boards, solder very tiny components and so on, I will take it there on Friday if Wednesday's clean isn't a success.
