Is it possible that I can have damage my monitor by placing a Big home theater center right ontop of it, I have a CRT model. My brightness have gone so low that I have to crank it up so high by software becourse my monitor is already set at highest. It works with games and applications that uses windows brightness but movie are still working on default settings so I can't see what's going on at all. I suspect that this is an damage coused by my centre speaker, but is it possible that this can occur? The monitor is only 3 or 4 years old and it shoulded be dark already by age. My monitor is an LG 99G 19".

yes david

Well I think that CRT monitors have a lifespan of about 3 years anyways. But I'm not sure if a 'big home theater center' would help. Even if it is insulated, those are powerful magnets - right? I once brought up a pair of my father's old Fisher's, a reciever, and hooked everything up to my computer. The two-foot tall speakers were in each corner of my room, but even being that far away they still screwed up the images on my computer monitor and my television. It was amazing. (Yes, I got rid of them immediately.) - Steven

No point in beating around the bush is there Dave! Your speaker contains a large magnet which can distort the monitors electron beams. This in turn can damage the phospher coating on the inside of the screen. Often degausing can cure the problem. Sometimes not. Move the speaker away from the monitor. It is likely that this will not fix your brightness problem. I recommend you take your monitor to a TV repair shop and have them adjust the internal brightness setting.

Three feet, rather. Two or three feet. Heh.

The speaker should have been shielded. Most home theather systems mean for you to set the center channel speaker in close to the tv. A computer monitor however is running at higher resolutions and faster refresh rates. Makes it a lot more vunerable to magnets, transformers(like in a florescent desk lamp), and the cat sacked out on the air vents. Get it checked out by a tech you trust. You might have to replace the tube in which case it's going to be cheaper to buy another monitor. Or maybe just get away with making some internal adjustments. I may be crazy, but I'm not stupid...

re the comment about mnitors lasting three years. I use a 17inch IBM monitor that is 12 years old. It was used in an office (on all day) from 1993 to 2000, and then the company i work for got new ones and said the staff could take the old ones homw if wanted. I did and have used it since then (every day, but not all day).
