Good Call Blair, Mad Amusements is great to deal with.   

There is also a update cable for these displays from marco spec which is only about $8 or $12.
I have seen dodgy ribbon cables on these larger displays which does cause all sorts of issues. replace the cable and it can be a real cheap fix.

I have the large displays on my Frankenstein and Batman Forever, and luckily, they are perfect. I did buy a spare NOS large display last year cheap just in case i need one in a year or three. Hopefully the Baywatch one can be fixed. See if Mark C has a replacement cheap before auction end ?
