[Electrical] C6501 Garbled Screen

[mrwho]

Good afternoon, guys and girls!

I've had the honor of checking out a machine with a most peculiar symptom. If you could please take a look at the following video, I'd be very thankful to know if any of you ever had one of these and what could be causing in (I suspect the front power switch).

the front switch is a gate photo sensor. have seen 1 unit with the pole type display do something similar. turned out to be the cables inside the tube were stressed by flexing and intermittently open.I assume a different op panel was tried.

Re: C6501 Garbled Screen

Thanks for the insight. I had no idea the front switch was optical (never had to replace one so never had the chance of dismantling one).

As for the panel, also no, as we don't have a spare panel to try. Since this is a somewhat rare ocurrence and when it happens the customer goes around the problem by using the web panel, we're waiting for an opportunity (read: slow time for us and the customer) to dismantle the panel and see if anything looks amiss).
