My PowerBook 160 sadly developed a vinegar syndrome after being stored for bit more than 2 years. Other similar aged PowerBooks in my collection are still fine, also being stored for same amount. I opened it and found out that the panel is Sharp LM64P58. I saw few videos about replacing the...

Hey I just got this 512K in somewhat sorry shape. Has some screen burn in, the case is super yellowed. And of course, the machine doesn't work - fuse is missing, this was told to me by a previous owner who examined it before. But it has SCSI and RAM upgrades (some snap on thing) But the main...

Hey, I am wondering what should I do in terms of preventative maintenance on a PowerBook 165c? I heard that screen should be recapped. I had it done on few before - like 160 and 140, but that ones were clearly defective (contrast all over the place, etc.). And caps were leaking all over the PCB...

Hi, I had a 512K in the attic for the last 10 years. It has a bad analog board and the mainboard was upgraded to some point. The machine also had some Hyperdrive parts there (like the PSU, fan and interface board that plugs over the 68000). Also the mainboard displayed a sad mac and didn't work...

I got this quite nice looking PB 190 few months ago. The seller did say it would probably need a recap of the LCD as the image is changing contrast all the time and is very temperature dependant. I was sceptical about this as those machines were supposed to have "good" caps in them and not the...

Hi, I just fixed one Lisa 2/5 that had screen jumping vertically. The jumping became worse as the machine warmed up. Main culprits were three electrolytic capacitors on the analog board that have leaked and corroded the surrounding areas. These are three 16V 10uF capacitors that were purple in...

I just repaired (recapped and cleaned the PCB) a PowerBook 170 Power Adapter M5140Z (APS-20E). Needed all of the brown ELNA capacitor replaced. 47uF 50V, 82uF 16V, 180uF 16V and 1200uF 16V were all leaking in the bottom. I was lucky as the corrosion around the caps was still minimal, so I...

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 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 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...

I recently got a nice condition Macintosh Plus with one major problem: the previous owner got it from USA and therefore it was a 117V unit. Which he plugged into the 230V mains that we have here. He said that the machine even started up and ran for a few seconds, then it died with some smoke...

Anyone knows of a suitable aftermarket AC charger to use with an PB1xx series of laptops? I guess that 7.5V 3.0A regulated PSU should be okay. I own 5 of these PBs, but I only have one charger for them. Used ones are prohibitively expensive and almost unavailable in the Europe. Thanks

I just acquired a PB 140 in a very good condition. It needed some stuff to be done (recap the LCD screen, lubricate head bearing in the HDD as the HD wasn't recognised, etc.). The funny thing is, I got it from Germany, the keyboard is US and the system is Japanese (System J-6.0.7.1). However...

I powered my trusty old iMac G3 Rev A after about 2 years. It powered right on, and it stayed there, until the sleep timer kicked in and machine went to sleep. When I wanted it to wake up, it did wakeup, sorta, but the screen was blank with the green light on. When I turned it off via a power on...

I just acquired a mint condition Classic II. It was described that it shows only checkerboard pattern. When I got it, it powered on and it showed checkerboard without chime. The HD also starts. Then I recapped it, but now the screen remains blank, also without chime. The logic board was in...

I got a 512k from a friend. He got it from someone, and that one completely took it apart. Also the case is painted with some ugly beige Apple Snow White wannabe color, that needs removing. Brake fluid prehaps? The logic board is modded, there is a MagicSCSI card installed. Analog board has...

I just finished fixing up a Mac 512K. It works like new, including the internal floppy drive. But the external 400K drive is making me mad. It is a SONY OA-D34V-22. At first, the mechanism was stuck. This was easy to remedy. I also noticed that the pressure pad was missing. But then, when I...

I just bought myself a nice condition PB 520c which was said to be working. When I powered it on, it only showed white picture, so I guessed that the contrast must be off or something. I perhaps saw a very very faint picture in the background of the Mac OS loading screen. The contrast control...

I am testing a PB 170 which has a bad hard disk drive. I connected the HD-30 SCSI dock adapter to it, but at startup it won't enter SCSI disk mode, instead it just stays at the blinking insert disk icon. I tried the same cable setup with the PB 160 and 170, and they both work flawlessly. Is the...

I got a Duo 230 in unknown state. When I powered it on, it worked, but it was unstable. I then examined the capacitors on the board and found that every one of them was leaking, so I replaced them. The Duo turned then on and it worked for a half an hour or so, but when I tried to power it on...
