Thanks @Byrd ! this unit is really back from the dead ( nothing was working when I got it ; even the power brick is dead ) and it’s nice to see it start. The recapping was relatively easy once you have the right components ( it took me 3 orders to get the sizes right ) but the recapping of...

I’ve read those theories but I find that if they are true ; the fix must be incomplete I can admit that this may be due to moisture ; but for me it makes no sense to heat the thing in the oven without , later , preventing the moisture back in ( like by sealing the edge or something similar )

I’m still waiting for a scsi2sd which will be a bluescsi ; I’m importing there in Europe ; the package just got delivered to the company that will send it back to me when I see a pb100 with a better screen I’ll probably swap

Hey, just wanted to share how proud I am of my "extreme" repair. :cool: This PB100 screen has a problem I don't really understand. At first I thought I caused it, but the more I looked at it, it seems I did not. I got the PB100 is a sorry state ( yellowed, stuck hard disk heads, needed a...

i'll tear it apart tomorrow and try to find where the liquid resides. I have a small hope it's just between the alumium foil at the back and the glass panel ( as I don't see the stain moving when I poke at the screen). If it's there, it should be relatively easy to wipe. If it's indeed inside...

Little update I’ve now entirely recapped both motherboard and screen and put it back together it works ; it doesn’t make the horrible « caps are burning « sound it use to do I’ve booted on floppy and all goes well but … indeed the screen has a problem ( as you said where the mouse hits )...

Yes now that you say it ; it’s probably where the trackball would be

There is a small zone right in the middle of the lcd that is weird ; it looks like a space invader made of pixels that appear purple or blue depending on the angle ( screen turned off ) I guess this is no good news ; is that kind of an lcd leak of sort ? It’s currently very small but I guess it...

All screen electrolytics test as « open circuit « in my el-cheapo ESR meter ; they are dead as can be

Wow recapping the screen of a PB100 is not for the faint of heart. I chose to put electrolytics again as they are the only ones that fit. I was unable to remove the white plastic, I just cut a bit of it to make the repair easier. This recap is the most difficult I've ever done.

Some of the difficulties - Most non SMD electrolytics are actually low profile models, I'm not sure regular models will fit. Thru hole tantalum are too high. I just ordered new low profiles ones. - This is especially true in the lcd inverter board, which has very little clearance. Looks...

Little update, Every 10uF SMD and every 1uF SMD leaked (frosty joints, brown residue), strangely enough every 47uF looked fine. I'll replace everything. My Victims Work in progress

Thanks for your time @desertrout ! I've also used your signature style as I found it cool and useful :) I'll finish my Farnell cart ( similar to digikey over here in europe ) , wait for the parts, and get going. I'm also retrobrighting the PB100 by the way, a process I've already tried on a...

thanks, at least I know I go in the right direction, I've just opened the display on the PB100 (which isnt super easy) but I fail to see the 8 caps, are they hidden like behind the display ? I did see two electrolytics on the inverter board but in my case, they do not seem leaky. I'll of...

Hello, I've got a few powerbooks to recap, - a PB100 that "somewhat boots" but screams for a recap (every 1uF on the board leaked!) - a PB180 that works flawlessly, apart from the screen tunneling - a Duo 270c that does not boot. I've recapped older things (Apple II plus, Apple IIc) but never...
