Have a 2005 Yukon XL with overhead DVD Entertainment system. For some time now
the dvd screen has gone blank. I can hear the dvd sound at the menu to start the
dvd but cannot see anything on the screen. I have tried sourcing the RSE through
the DVD but have had no luck. It is hard to trouble shoot without seeing
anything on the screen... Would like to fix it rather than replacing...
Most earlier model LCD screens had a CCFL light embedded into the LCD
display. This is a tiny florescent straight lamp with lead wires on
The first issue is getting the display apart to get to it.
It really not meant to be changed. When you get the display tore
down, then you have to source the lamp.
There is also a chance the high voltage power supply the powers this
lamp is defective.
You will need some electronics and soldering chops to work on either.
