True, as I know vinegar syndrome is a common issue relative to all LCD panels, where the polarizing film glue deteriorates, making bubles, watermarks or even cracking the film. This deformations on the film causes image distortions, stains and so. The tunnel effect is a particular issue of the...

We’re fine, thanks! It seems the worst is over. My wife works in a hospital and she says the situation is getting better. Refering to the screen, I think the key is heating it for a long time and in a dry environment to let the moisture go out.

Bingo! Yes, that’s catalan. I’m from Barcelona. Not a lot of OS’s were translated to Catalan. Only 7.1 and 7.5.3 I think, or at least I have. And then nothing until Lion. About the screen, I think it turned black while it was in the oven, it was hard to see. I kept it between 80 to 90ºC for...

Second cooking was a huge success. I left the display in the oven for the whole afternoon and the tunnel effect has completely gone, while the screen still “burns” and windows and menu bars are still visible for a few seconds. Nothing to do with a passive display such as PB 100 or 140, but way...

It worked pretty well actually. First pic is 10 minutes after powering on. Second pic is 20. Darkening is still there, but it improved a lot. My bad I didn’t take pictures before, but by the time the mac boots to desktop, almost all the screen was black. Also, after shutting down the menu bar...

Hey, great post! That saved me some time. This nasty thing is so going into the dish washer machine…

Winner winner screen dinner! It’s a PB 170 screen with a huge tunnel problem here. Corners begin to dark after a few seconds and in a two minutes nearly all of the screen is dark. According to major opinions in this thread, I will bake for three or four hours at 80-90ºC and see what happens...

Even with lifted or missing pads, you could still save it. You can peel the coating on the traces and solder the capacitor, or a cable, directly to the trace. It's not beautiful, but it's effective. Always use solder flux if you try to do this. Also you could follow the traces and solder the...

Dunno, but mine got a new batt in 2006 and it still holds up to 5 hours of battery. I really don't understand… 

Did you clean thoroughly the boards after recapping? Sometimes electrolyte residues short the circuits, causing this kind of errors.

Maybe you could use a linear voltage regulator like L78S75CV for example. Using a 12V powerbank it would limit the voltage to 7.5V up to 2A. I'm not an expert though, I'm just giving the idea. https://www.mouser.es/datasheet/2/389/cd00000449-1795347.pdf

Nah, J11-28 is connected to a couple of logic gates on the left side of the board, so it doesn't look like to follow the schematic from the M5120. I'll try to get a new RAM board and see what happens.

It doesn't bother me, it's just curiosity, as in all videos I have seen the backlight starts right away. Well, I found the same card I have on Ebay, and it's stated as a M5126 model, so I guess I have the correct one. So now I'm checking the J11 RAM socket on my board comparing to the...

Dear Mac enthusiasts, Finally I could figure out what was wrong with my Mac Portable backlit model and I brought it back to life yesterday afternoon. Not a really big deal, just a broken path, but it was under a chip, so it was quite difficult to find. Anyway, now that it works fine I have a...

:(

Hey @macalle69 I've got a similar problem here. Did you find the issue? Thank you!

Hello there! I need some help here. Maybe @techknight can give me a hand, as I have read some of your posts here about this model. I bought this Portable from ebay that won't do anything at all. I bought it recapped and with new mosfets in Q1, Q15, Q16 and Q20. At first I though it was a power...

Hello, Reasons, Have you checked the voltage on the motherboard? You could have a problem there. The easiest and safest way to do it is on the external drive port. You should have 5V on pin 6, 12V on pins 7 and 8 and -12V on pin 5. For more information look at pages 8 and 9 on classicmac2...
