Advice on PB180

[haemogoblin]

Hey guys

Recently added a 180 to my assortment of macs and I've been reading up on screen tunnelling as my laptop is demonstrating some of the signs down the right side of the screen.

I was wondering what if anything can be done, for instance can you swap the screen out? Maybe with one from a 145?

It's a lovely laptop and it seems a real shame that the screens eventually going to make it unusable

I have read that nothing can be done as this usually means the LCD panel itself is delaminated and moisture has gotten in from the edges. One thing that might help slightly (but temporarily) is baking it in the oven - but as for temperature and duration I have no idea.

I'm not sure there is any replacement screen other than another PB180.

That's a darn shame,I was sure other screens from the 100 series were compatible.

Only way to know for sure is to give it a try. Don't destroy a working 170, but if you find one wit's blown hinges or dead logic board I say give the swap a go.

Might give it a shot, do all the 100 series suffer with this? I was under the impression the 145 doesnt

they all suffer from broken hinges, plastic, tunnel vision, ETC

I think the logic boards of the 140-180 are all more or less the same, so likely any working screen will work on your 180. You will find, however, that a screen like one from a 160, etc., will likely need capacitor repair — which can be done relatively simply.

You will, however, do best to just get a working 180 screen, as they are ... what's the word? ... magnificent. There's nothing as clear for text work etc. from that era.

IIRC its only the active-matrix 100 series that have the tunneling issue, so the 140, 145/145b, 150, and 160 should be okay. 

 

[haemogoblin]

That's what I thought, I had this impression that certain models didn't suffer with the tunnel issue. Just bad caps.

 

[haemogoblin]

Beachy I agree the screens are clear, but surely getting another 180 screen is just delaying the inevitable. Aren't they all going bad?

 

[beachycove]

No, I've had a good one. Flawless, in fact.

Sold on, sorry.

Cory5412 and I both have very little tunneling on our 180's. We suspect the arid Arizona climate might have something to do with that.

To add, mine came with some tunneling (it was in Baltimore/WaDC before) and now that it's been out and about in AZ it doesn't tunnel at all, even if I leave it running (although with backlight off) all night, or for a few weeks at a time.

 

[haemogoblin]

Would it be wise to remove the screen and perhaps put it in the ovan for a short spell at 150?

On the defective tunneling screen?  It honestly can't hurt.

After my old flip phone (back in 2008 or so) took a swim in a saltwater pool, I dissasembled the entire thing, washed it with rubbing alcohol, then put the entire thing (minus the battery) in the oven on a cookie sheet covered with aluminum foil for 2 hours @ 170 degrees F.  It came out working again

Obviously, my 2 hours @ 170 degrees F is a sample size of one and on a cell phone with a much smaller display panel, and may not be safe for the LCD from the PowerBook.
