I bought a used KDS 17" color monitor, Rad-7,
I agree that the overheat was the supply being too small. Not only the voltage rating is wrong, but I'd bet the amperage is alsotoo low for correct operation. Check this link.

They ship pretty quickly as well. http://generalsaving.com/productfile/G_LCD12V3A/1000/G_LCD12V3A_z_0157.php
