I got a pioneer avh 7500 that is past warrenty and have the backlight of the monitor gone out. so i took it to the local electricia and he fiddled around for a month before telling me that he had no idea how to fix it. not all handy men are handy i guess. so now i'm wanting to take it to an authorized repair shop but wondering how much it will cost me and the wait time just to get the repair id processed. what do you guys think? thx.
