You last helped me on December 4th and resolved my questions well. Now, I have a completely new problem to solve that is very critical as it is preventing me from using my G4 Desktop computer at all, and I am writing to you on my G4 Titanium Powerbook as my backup.''
The current problem started a few days ago and came out of nowhere without any warning. It began when my monitor, which is the 21" model of the same generation as the G4 Tower, with a clear plastic frame, suddenly went dark for a second or two and then reappeared again. It's as if it goes to sleep from lack of activity, but in this case it happened when I was using the computer. I hit the space bar thinking that it was putting itself into sleep mode, but that didn't seem to have any effect on when the monitor lit up again. It just came back on when it felt like it.
Since this problem started, it has gotten progressively worse each day, with the failures of the monitor taking place more frequently and failing again after shorter periods of time. It's as if something is wearing out bit by bit. When the monitor finally stopped coming back on at all, I had to shut down my computer using the on/off switch, then restart it. The monitor would always work at first after a restart, but today that has stopped working too. Now, I can restart the computer and it appears to be starting up normally, but the monitor does not respond in any way.
I should add, that when the monitor went off while I was using the computer, writing a document or printing a file, the computer was not effected by the loss of the monitor and continued to accept the words I was writing blindly, or finished printing the file, as if nothing was wrong. When the monitor came back on I could read the additional words I had typed while it was off.
There is some kind of a device (small plastic box from Apple) in between the monitor and the computer. The cables from the monitor connect to it on one side and come out the other side to connect to the video port on the back of my G$ Tower. I thought I should mention that too.
I am still living in Mexico, as I was when we last exchanged questions and answers in 2013, so I don't have access to another monitor, computer, or the small connecting devise I mentioned.
What do you think is causing this problem and how can I fix it? I am really up the proverbial "creek without a paddle" right now, and need to be able to use my desktop machine.
