Hi Lene, Okay, here's what I think. I've got a book about repairing monitors. I'm not an electrician. The book says you can, after a time, have some of the soldered connections break through, while the wire remains in place and the soldered joint looks solid. It's called a 'cold solder joint' (why, don't ask me). Perhaps there is microscopic corrosion or dust, and slapping the side jolts the cold joint and once it touches, it maintains the connection somehow for the duration of the session. Then you switch it off, and next time, same problem, you slap it again, it works for the session, or maybe needs another slap now and then. I wrote to the guy who wrote the book and told him about my problem and my guess that I had, as he described, a cold solder joint. He wrote back; quote; "In regards to your monitor problem, it sounds like you are correct in your diagnosis of cold solder joints on the crt board. It is an easy repair to make so it is definitely worth doing sometime. Good luck with your endeavors." The 'repair' consists of taking a fine point soldering iron, and touching all the soldered joints on the crt board, remelting and reconnecting them, permanently curing the problem. However, let's get a little dramatic here, and imagine that inside your monitor case, once you open it, is a label of a skull & crossbones grinning at you, and a warning notice 'DANGER - proceed at your own risk'. There isn't, but there should be. If you look at the funnel/cone-shaped monitor tube, there are two wires that go to either side of the cone about halfway between the narrow and wide ends, and disappear into a rubber cover about the size of a large round button. Under that rubber cover, the bare wire ends contain enough static or residual voltage, AFTER unplugging the monitor, to kill you. There are other dangers. You must know them all, and what to do about them, before opening and playing with all that fancy wiring and circuitry. This is in Chapter One of the guy's book, the chapter on safety. If you want to buy a copy of the book, it's only about $10 or $12 US, and his email address is; tonyandreneej@xxxxxxxxxxx and his name is Tony Jomaa. The other end of the particular wire mentioned above (one on each side), wherever it goes into the crt board or coil or whatever, could of course also kill you. Some of his safety rules are, always keep one hand behind your back while working on a monitor, so you don't touch it with both hands at once, completing a closed circuit with your heart -the most vulnerable part of your body to electric shock- in the middle of the circuit. Always ground your monitor chassis before working on it. Always wear rubber shoes to keep yourself ungrounded. Don't work on a carpet or in dry dusty conditions as static electricity can kill your monitor chips. Etc. etc. Personally, I decided not to mess with it myself. I had the book, and still do, and I knew what to do, but I think I'd rather play with throwing rocks at beehives than fool with this kind of thing. So I just kept happily slapping -as in 'slap happy' :)- my monitor several times each time I started a computing session. Finally a neighbor said he had an old monitor I could have for $10 and I was fixed up with a newer unit with better shielding, and I keep the old slappy one as a spare. The book made me better informed, and part of the way I used the information was to decide not to play with monitor insides. I could, but what the heck. Keep your eyes peeled for someone's used monitor and it will show up sooner or later.
