Did I kill my monitor?

I have a 15" monitor, I was using it one day and i think I maybe cranked up the resolution higher then the monitor was supposed to take, now when I hook it up all the light does is flash(like it does when it's not getting a signal) and nothing appears on the screen. I tried a differant monitor on the card and it works, so it must be the monitor. Did I break it, or did I just blow a fuse or something. I need to know, cause I just sold this to a guy, and I don't want to send him a bum monitor.

Sounds like its a gonner to me.. you can definitely push them out of range and kill them if you arent carefull. I would save yourself some grief and just toss it if its out of warranty.

I bought it at best buy, not sure if I got the warranty on it, I know I got the warranty for the computer at the same time. I will have to get another reciept printed out.

I think it's just coincidence. If you crank the resolution too high, the screen will just become distorted because it cannot handle the refresh rate. Damage from running a monitor out of spec, I believe, is after a fairly long period use (many hours) after which the picture will suffer a serious loss in quality. I don't think it would "FRY" the monitor to a complete death.

Most users fail to install the proper INF monitor "driver" for their specific monitor, a common error. If you would have done this, you would have been assured there is NO WAY to run the monitor beyond its design specification. Read this: PNP Monitors

While this doesn't solve your immediate problem, it will help you in the future.

Good Luck! :D

Digitally-controlled monitors (about any that remembers the settings for each video mode or that has an on-screen display) should be able to prevent operating at excessive scan rates, but too high a horizontal scan rate can short the horizontal output transistor and pop a fuse. Horizontal transistors range anywhere from $3-$120 and aren't that hard to replace.

How do I find that, I have already opened the monitor once, but am not 100% comforetable working in there. Can you help me find a way to find it?

If you're not 100% comfortable working in there...DON'T. The CRT has a very high capacitance, you could easily electrocute yourself.

Yeah I know about the capacitor, that is why i don't like working in there, but since I know about it and know to avoid it, I think if it is easy enough to find that fuse, that i could replace it.

I think he meant that the fuse blew cuz the output transistor fried dead short. So you would have to replace both, probably means unsoldering and resoldering a medium solder joint. If it is under warranty, this will definately void it. I would try a defect return to Best Buys, they almost always give a 30 day return for new, and usually up to a year they will RMA or repair for you.

Well it's been more than a year. I bought the 3 year plan for the computer, but not sure if it covered the monitor. If it doesn't, anybody know what i can do with a dead monitor?

Check the warranty on the monitor, you might get lucky and have it be 3 years, then the only cost would be shipping one way to the manufacturer.

Otherwise, check repair shops in the area if you don't feel confident to do the repair yourself. You might get it fixed cheaper than buying a new one. Otherwise see if the trash bin will fit it.
