How to make a headless older PowerBook work
This is probably the best forum I'll find for comments on my TiBook display problem. Periodically, roughly once per day, the display will (1) stop re-drawing and at the same time (2) go berserk by displaying inappropriate images. The "inappropriate images" are of several styes and may appear in different combinations; they may also morph from one to another. First, the displayed image will fade and gain perhaps some narrow vertical or horizontal stripes. Then, typically, it gain wider stripes of various colors, then continue morphing the fade until there are green organic-shaped blobs slowly morphing on a mostly black background. (I'm not kidding.) On some days, the display will suddenly revert to normal functioning for 1-3 seconds, then start over. If left long enough, it might become all black or all white, but then can start up with the organic shapes again. Almost never happens immediately upon waking from sleep if the machine has been asleep for several hours (e.g., overnight), but will almost always re-start if it has already begun and I just do a quick sleep-wake cycle.

I had what sounds like the same problem on first edition TiBook. Vertical white lines would appear on the screen, gradually filling it. If left alone, these would eventually become greyish blobs. This might occur within seconds or possibly hours of opening the lid, but got progressively less, until it became unusable without an external monitor. |
