Can an overheated Video Card destroy your monitor?

Recently my screen was displaying shards of colors at times and occasionally my monitor would flicker. I think this is a video card issue, but now my monitor seems to have died, as it has power but no picture. Can an overheated video card (i found that the heatsink was clogged with dust) burn out a monitor? Thanks.|||Are you sure its not still the video card? Try it in another computer and see if it works.|||No, it is quite impossible that a signal of your Video Card can destroy your monitor. If it would send like false signals or some weird input Hz, the monitor would simply go out of range. Check the monitor once again with another source. If it doesn't come up the monitor is dead, if ok then likely your video card is fried.
