Hi, I'm loosing faith in my trust old PBg4. A thin (1px?) magenta vertical line running from top to bottom of the screen appeared about a month ago. A second (in a lovely blue) appeared to it's left a week or so after that. My monitor is now adorned with 10 lines in various colors and distances apart. First, ideas about the root of the problem? Second, if a fix is expensive (especially given that the age of the PB may mean it's wearing out in other ways), could I use an external monitor and keyboard, or do you think the problem will persist on that monitor, as well? Third, if that's a good solution, recommendations for monitor (it would have to be about 4-6 feet away) and keyboard. The reason the monitor would have to be so far away is that I have a temporary (I hope) disabling lower back problem. I can't sit up for long in a normal chair, so I use a special recliner. Working with the input on my lap is vital. I am not currently traveling with the lapttop for obvious reasons. I also can't afford a new one (catch-22, not working til I find a remote job) unless I go majorly into hock. I appreciate any ideas folks may have.
