Hello to all,
I have a Dell Monitor (Nokia Model D447S063), which has a problem.
At first, it started making a hissing sound, the picture was fine. I stopped using it, and then tested it again after a while the hissing sound dissappeared, this time it makes a clicking sound, and the picture shrinks and expands a little.
Our local TV engineer did not even want to know about the problem, he said monitors are not worth fixing, but it seems wasteful to throw it away.
What could the problem be? - What components need replacing (I can read schematic diagrams and can solder competantly), but I am not able to work out the problem myself without some help!
Also, is there a circuit diagram available for download?
I would be most grateful for some help.
Thank you in advance,
