Screen problems I'm about to get a new MacBook Pro and would like to sell my PBG4. But the screen is acting up - sometimes completely black, but more often just the bottom 2/3 will either be black or keep the previous image frozen. The top third is usually okay, and with a little squeezing, the whole screen comes back to working condition. I don't want to sell my PB like this and would like to have a dealer fix the problem, but I don't have a lot of confidence in their getting it right at a reasonable cost - (about $100-$150). Otherwise, it's not worth selling - I don't think I can get more that $5-600 for it, right? Any ideas about how to advise the service dept. of the Apple dealer - they already told me "never heard of that problem", which didn't inspire a lot of confidence... Or is there a possibility of checking for a fix myself?

If it is a loose connector and it would seem like it, you can open up the book and inspect the cables between the lcd and the motherboard. the vga itself is most likely not replaceable wihtout replaceing the motherboard.

Hi-

Hi try calling this number instead for an estimation and repair.

If you're not afraid to tinker Here's How one guy took his apart.

Lots more good info at Power Book Medic

Once inside make sure all cables and connections are secure. These things seem to sometimes wiggle loose over time depending on how the laptop was used or handled.

Good Luck

Does not look a software fault , rather an hardware problem.
This is either a faulty video adapter, or a bad lcd ribbon cable, you do not get any job of this kind done on a laptop for less than $100. It takes $50 only to diagnose the problem, probably repair will be around $200.

As Abrsvcs pointed out, the graphics card is built into the motherboard. Most likely a cracked solder or faulty connector ribbon, that is best left to professionals to replace and diagnose. I do not think it is an LCD fault, or else you would just have a black screen.. My guess is a faulty ribbon connector. This shouldnt cost too much to replace, but I wouldnt recommend you doing this yourself..

Click this site they give an instructional guide or do-it-yourself in how to replace the LCD or the inverter;

Greetings,

Video Card or LCD that's causing it. It's a hardware problem.

Problem with Mac's is all parts are proprietary.
You can have it repaired and get small amount from it or sell it very low price. Don't take the risk of getting it repaired cause you might end-up spending a fortune.

FixYa for all your troubleshooting needs.

If pressure returns the screen to full function, there is a connection problem. The issue is whether or not this can be fixed without replacing the panel. If you ned to replace the panel, the cost will be close to $300. There is no way to determine if the fix requries the panel without opening up the case and examining the ribbon cables and the panel connectors. It is possible that one of the cables has a hairline crack in it.

If you feel confident enough to open up the case, do so and examine all of the connections carefully under magnification. Be extremely careful when opening up the top that you don't rip the cable by accident as these cables are often taped to the panel.

Keep us posted.
