  • Sorry for posting it before as an ANSWER.. Well now i am also getting a burning smell from inside.Should I now check the transrormer or the Picture tube? Has it gone for ever and irreparable? If I want to replace that with A TFT will it be a problem because the resolution is already set to very high?

You no doubt exceeded the resolution it was capable of.

If you're getting a sparking sound you probably destroyed it. Most modern monitors won't suffer damage from this but the older ones certainly could.

When you add more lines to the screen you increase the pulse rate on the flyback transformer and the voltage goes up. It's already very, very high.
