Does anyone know if the flat display cable of the 190cs (see pic) and the one of Powerbook 190 (grayscale) are interchangeable? Thanks!

Hello Byrd... well, not so easy to find it in Italy... quite easy from US but quite costly because shipping and importing taxes... 🙄

Thanks for your advice, yes I've seen a couple of videos about replacing the film, is not easy and even the film is not cheap anyway I'll check this possibility.... Don't know about the label, perhaps it has to do with the Italian market?

Hello, any advice about fixing this shadow on the LCD panel? Is this the "vinegar syndrome" or something else? Thanks

Hi, I've got a "packaged new from factory" board replacement for Powerbook 190. Already tested and it works. Question: should I recap its electrolytics capacitors before to finally mount it in the PB190?

Hello, does anyone know what this component (the black box in the pic, labelled 157S0166) is? It is from a Powerbook 190 logic board. Many thanks.

Does anyone have a checkpoints map for the PB190 logic board? I need some checkpoints near the on-board power module in order to check the expected voltage on the motherboard for a suspected problem on the onboard power module. Thanks

Left on for a couple of hours..... I can try longer...

I think so, it is probably power/PRAM related. I tried to leave it for a while but no changes :(

Yes It was recapped 2-3 yr ago. Moreover I've done a test replacing it with a lab power supply and got same behaviour.

HEEELP!! I restored my Powerbook 190 cs it 2 years ago, it was working perfectly until yesterday. Only problem was the PRAM battery to be replaced. After I replaced the battery (identical to the original) it worked for a while then stopped to boot. No way to restart. After several trials I...

No, you are not alone..... I've resurected another one after that one. :ROFLMAO:

Finally !!!!

Hello same problem here! Did you fix it?

Hi! Is there anyone who has a high resolution photo of bottom side (not component side) of original StyleWriter logic board? Note: there are 2 version of original SW, I'm looking for version 1 - the one in the pic. More over, anyone knows if a schematic of such logical board is available...

Exactly as mine. I disassembled the engine and carefully cleaned it with acid and oiled it, now it is fine. PSU: interesting point, i has only a capacitor or two and are not leaked, but I measured about 13V while in label reports 9V .....

I'm using a cartridge from ebay that was sealed. I think cartridge is good, does not seems clogged, the ink is not dry. Unfortunately I don't have another working printer to test the cartridge.... but it seems to me like the board does not drive the cartridge. I just mapped and checked...

Exactly! As suspected leaky caps have caused some more damage to the logic board. I just found 2 more corrosion under one stepper motor. Once fixed it paper management and printing movements behave correctly but unfortunately no ink is brushed on paper. Need more investigation to understand...

Hi all! I'm restoring an original StyleWriter V1. Using original power supply and a BC-01 cartdrige, after first turn-on, I've tried the 2 auto-test modes: (form-feed+power-on and ready+form-feed+power-on) but it behaves strangely, lot of noise, error light and so on..... I've opened it...
