Powerbook G3 Screen Problems

By MJackman ·
Assistance is requested with troubleshooting the following:

What: Powerbook G3WS, 1998 with new power adapter per 2001 exchange
When: In the last couple of months

Sometimes the screen lines out, shakes, then blacks out. The computer needsto be restarted and computer seems to be
heating up/wearing out during this process.

According to the local Apple repair crew, nothing is wrong with the monitor or with the basic powering mechanisms of the computer.

However, surely something is amiss, since this problem has repeatedly occurred during limited, normal usage during the last couple of months.

Any suggestions as to what the cause might be, and how to go about fixing it would be most appreciated.

Thanks in advance for the advice of experience!

Have you installed any of the firmware updates for this model G3 located at www.apple.com?

Michael,

If this is happening with just the battery, your battery is probably due for a change. Also, if the power adapter is a tight fit, or you knocked the connector, you may have caused the connections on the inside to ever so slightly crack,causing a good connection at times and a faulty one at others.

Take care,
Ted

My recommendation would be that, when this starts to happen, hook up an external monitor to your machine and see if it still does it or not. In my experience, this kind of problem is usually with either the screen itself (rare) or the inverter board(common) which processes the signal from the video card to the screen. The best way to isolate this is to do the aforementioned procedure. By the bye, there are not firmware updates even coming close to this issue (although if you haven't done them, it might be a good idea. I would be interested to know just who your 'Apple repair crew' is. Whenever I see a problem like this one, I have ALWAYS found it to be a hardware issue. My opinion is that the problem is either the inverter board (which, I believe, is in the screen) or the video card. The monitor procedure will isolate that for you. If it still does it with the monitor, then the problem is with the video card. Also, does it occur more frequently after using it awhile? If so, you have heat fracturing going on, which only shows up after a decent amount of use. If you take it back to your 'Apple repair crew', they will need to know this if it is so. Hope this helps!!

Excellent advice - the result was that the problem occurred with the external monitor as well. The video card, I understand, is soldered to the mother board in this model. It does occur more after some time - and I think it is related to a head problem. You got me closer, thanks.

Sounds like a hardware problem. Probably the
power board, sound or logic board. You need
to bring it to an Apple Specialist.
If in NY i recomend Alliance Computer
Systems.
