Probably the suicide fuse is blow, it can be replaced with a suitable thin wire. Located on the main battery PCB. 3 pin device. Had this happen on two occasions.

I recently acquired a near mint condition PB G4 A1052 17 inch. The computer was from a friend of mine and it ran fine until about 4 years ago, then it started to show problems with GPU, artefacts, random lines and so. Not long after, it completely died. I know for sure that the LCD was good and...

I am thinking of 3D printing a battery pack that would contain 5 AA cell holders that would be accessible from the outside, so one could be able to use the cells they wish and change them on the fly. I think you could be also able to use alkaline batteries (include a switch for alkaline use that...

That would be the part to order: http://eu.mouser.com/ProductDetail/Littelfuse/1206SFS500F-32-2/?qs=sGAEpiMZZMsIz3CjQ1xegdajYV%252bSgOyhtRV3I06tmz0%3d

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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)...

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...

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

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.
