    iBook G3 Clamshell Charger Board Fuse F1

    I tore apart my parts Pismo and found a similar fuse there. It was located on charger board. This one is 5A and has Fairchild logo on it and also a "T" which means "Time Delay" or Slow-Blow. Replaced it with the one from Pismo and now it works. While I was there, I also measured 35V 100uF...

    iBook G3 Clamshell Charger Board Fuse F1

    I am repairing a iBook G3 Clamshell that has blown fuse on the charger board (F1). This causes the known good battery not to charge, despite the orange light on the charger. Can anyone suggest what is the original specification of the fuse? It has "5" written on it. Considering my electronic...

    Powerbook 520/540c Power Adapter repair/re-cap

    I would leave ceramic and plastic film capacitors alone for now. Except if these are actually paper caps you are referring to. You probably saw cracks in clear case capacitors near the AC input on 128k/512k analog boards. These are plain old paper (or paper in oil) capacitors (usually from...

    Aftermarket charger for the PB 160

    It works!! I got the charger today, it looks reasonably built, but still feather light compared to original one. It measures 7.80V at the output with no load. At first when I tried it, the barrel did not fit completely into the back of the plug, the insulating sleeve was too long. I then used...

    MiniScribe Repair

    I have two Miniscribe SCSI drives sitting on a shelf for more than I can remember. One of them worked, but it sounded like it was about to die. The other one was more or less dead, and I also used Silverlining, but it didn't help. Even when new, these drives were known for not being very...

    How Toasted is This Logic Board?

    I used to remove the capacitors by desoldering them, but I managed only to pull a pad every other time, which gave me headaches.  Now I use the method of twist and pull with pliers, with that method, I never pulled a pad. You grab the capacitor with pliers and then you twist it left and right...

    iBook G3 SE 466 MHz restoration

    Thanks. I realise that the missing peduncle would be common on these iBooks. 2/5 iBooks that I owned in the past had this thing missing! About time for someone to start 3D printing them! The DVD-ROM drive works perfectly, about as good as it was new. It passed my scratched CD and DVD read...

    How Toasted is This Logic Board?

    I would remove the capacitors and wash this board, perhaps soak it in warm soapy water for a few hours. Just make sure that you get this white residue off. Consider using dishwasher if you feel so, perhaps this would be the best idea. Then I would resolder new capacitors and with a bit of luck...

    iBook G3 SE 466 MHz restoration

    I got myself an unknown condition iBook G3 Clamshell. It came without the power supply, but it powered on flawlessly with my PSU. It booted to 10.2.8 in a matter of minutes. However, the keyboard was almost completely dead, only few keys were functioning. Removing it revealed that the laptop...

    512k repair

    Yeah, I am from a part of the world that was almost exclusively a PC country until 2006 or so, when the Macs became much more affordable and Windows compatible. I worked in a large ewaste recycling company in 2008 for 3 months and I only saw one Mac there, that was PM 7200 that was too far gone...

    512k repair

    Already ruled them out. They are the right ones, but sadly too expensive.  I will probably put this project on hold for some time, as I have other stuff to do. If that would have been a perfect conditon Mac, then no doubt I would already bought new flyback.  Will might do an flyback ring test...

    512k repair

    NTE might be compatible, but their cross reference application doesn't work with flybacks anymore. Also I searched for Wyse terminal flybacks and I found...

    512k repair

    Thanks for the reply! I searched ebay for new flybacks, but ones that I found are quite expensive. For the price of the flyback or little more, I can get the whole Analog Board. This one seems to be the cheapest (US $55.80 with combined shipping to EU)...

    512k repair

    Yup, the old transistor was cooked to death. I removed the flyback and now it bongs as it should, also the Q2 isn't getting hot anymore. By the diode, you probably mean CR5. I tested it on component tester and it measures OK (even reverse leakage current is very low). However, I inspected the...

    Pismo batteries... re-cell? No cycle counter

    Here is the fuse (circled in red) that I bricked with a thin wire.

    Aftermarket charger for the PB 160

    I checked the barrel and it seems like it will fit (5.5mm/2.1mm), so I ordered one. Will post back when it arrives if it is the right one and if it will fit and work.

    512k repair

    Sorry, I meant Q2 in the previous post. Changed the Q2 with new BU406. Now I don't get bong anymore. and the Q2 gets super hot after 20-30 seconds, also the flyback gets warm. Also, there are some goraning noises from the analog board. I do get some HV, as there is a weak spark when...

    512k repair

    I pulled the Q3 (HOT) out, as it didn't read properly with my DMM. Measuring the BU406 gives me this on my transistor tester:

    512k repair

    Hi, I had this 512k Mac stored in the basement for almost two years now. Since I applied the brake fluid and the case cleaned quite well, but still not to my liking. If I get this 512K to work, I might consider getting a new case. Next, I wanted to at least repair the Analog Board. I found two...

    Aftermarket charger for the PB 160

    I gave the eBay a quick search, and I found this one http://www.ebay.com/itm/AC-Converter-Adapter-DC-7-5V-2A-Power-Supply-Charger-EU-plug-5-5mm-2000mA-15W-/351354556853?hash=item51ce5d11b5:g:J7kAAOSwkNZUeLpu I know it looks super cheap, but perhaps it will perform like it should. I hope that...
