Stereo Receiver Background Lighting Issues?
 

the background light on my stereo unit has lately been either very dim, pitch black, or just all orange. it happens in intervals; it'll be fine for a couple weeks, then give me issues for a couple more thereafter. i took it to the dealer, who gave me some BS about how they'd have to replace the whole unit for tons of money and that an alternative unit (e.g. something from Best Buy) may not work correctly. anyone have the same issue? is there a quick fix for it? Thanks!
