Missing segments on the display
LCD dispaly is standard,
the brightness is controlled on the display control baord mounted on the board that the dispaly cable plugs into, the gain of an op amp that controls the brigtness of the diplay is loacted on this board , check also the potentiometer located close to the connector and adjust that, but a quick visit to radio shack will get you a couple of cents worth of parts and a few mintes of delicate soldering and a couple of hours of dissasembly , tracing and reaasembly. with a risk of doing further damage.
equally likely to a faulty power op amp or potentiometer is that the dispaly is expiring ( it happens sometimes to these types of plasma displays.....)
so if you are determined not to get a cheap relapcement cd 20 and are determined to open the beast. get a cheap broken cd20 unit and take the dispaly out of that one and replace it with your display ( by display i specifically mean the intergarted circuit tht the plasma screen is mounted to, and subsequentially screwed into the inside face of the cd 20 unit behind that bit of smoked glass,
which of course you are going to open and clean before you put it all back together gain.
have fun ;-)
