Hello, Customer brought this stereo unit "pre-diagnosed" from another shop that was unwilling to fix it. Customer purchased the Display,pn: AAV7007-A I guess from Pioneer. Hs good audio, just a dead display. 49 PIN display. I was skeptical that the original was bad but did the swapout desoldering the 49 pin unit to no avail. This is a 2 piece unit, tuner and amp (M-790). I need tips or a printout of the power section to see how the display is driven I have no service literature. Assistance is appreciated.
