Colour dissortion Recently i've been having the prob of dark display with my monitor,but thx someone really helped me.. nw the prob is that often when i switch on my pc i lose my red colour and my screen goes blur.. but after sometimes it goes alright.. when im really fed up i usually punch the monitor on top and i find that my true colour appears again.. why is this so?? somebody please help me..

Just open the monitor cover from back. just look for dry soldered transistor on the the yoke of the monitor. theree are three transistors for red blue and green. change both of them and your prob is solved. just again mail me further before attempting so. i will guiode u because it is so dangeros.

Usually, this is due to a bad connection on one or more of the wires in the monitor data cable. Either the pins aren't making a good connection to the port on your computer, or there's a short in the cable somewhere. If hitting the monitor solves it, it's probably a bad connection between the cable and the monitor, where the wires are soldered into place. If this is the case, I would suggest against trying to repair it. CRT monitors store large amounts of electricity, and a discharge while you are working on it can be deadly. Never open up a monitor case. Try wiggling the connection on the back of the computer next time and see if that fixes it. If it does, remove the cable and check for any loose pins, or bent pins. If there are any, the cable could be repaired, though 15" CRT monitors are so cheap you're probably better off replacing it. Look on craigslist.org for your city. If it has a cite for your city, it's likely you can get a cheap used monitor there.
