Hi Charles.
Don't have much on that model, but here is what I found in Winstips.
(Wish I knew how to cut and paste tips from Winstips.)
Check R908 for increased value. Should be 180K.
Check for shorted 33v zener D582.
Of course, on any Mitsubishi, check for leaky caps in the power supply
and resultant pcb damage, as well as cracked solder connections. I know
you know that, but list it for the benefit of new techs.
Not much, my friend, but I hope it helps.
