Hi all,
Would anyone happen to have any info on how the LCD is powered by the Switch.
I'm aware IC 8316 to the left of the LCD connector provides the 5v/-5v, but I'm also reading -7v on another LCD pin and I can't figure out where it's coming from.
Long story short, I've replaced the M92T36 and MAX77621 to get the unit to turn on, but I'm getting no image -only backlight. I can hear sounds, so I'm sure it's running, but it's not displaying anything.
IC 8316 is not outputting the 5v/-5v despite receiving the 1.8v signal, so it may be the culprit, but it would be nice to know where else the LCD gets its power from.
THanks for your help!
