Upgrades on the lighting to LED, A much better lighting system for these "modern" machines.

hello all, i have a m/plus igt double jazz machine that i tried the clear chip in and all i get is a CI in the display window.  I have no idea what to do.  any help would be greatly appreciated

Ok

I found the door key for Bally 6000 on eBay but they do not know if it also fits the E2303-4 model.  Do you know if they are the same spec’s?

Thanks much Chris - having a source for parts is a huge help.  I did a quick look at the EHT / flyback box - It's obviously had a hard life.  I need to order caps for it, but the semis on it check out.  With little to zero experience with these, I need all the help I can find.  I pulled the X-Y deflection board and power section.  The board looks good with no wonky repairs.  I''ll recap it and check the other components as time allows.  I found the the X channel power amplifiers (2N3716 and 2N3792 ) were both dead shorted.  I have those parts on hand.  BUT - I don't like the idea of just replacing parts and then firing this thing back up.  These semiconductors are getting expensive and I tend to feel there has to be a reason for the component failures.  Because one channel is bad - that would seem to eliminate the regulator as the cause of the fault.  If it had been the regulator board that caused the failure, I would think that both channels would have cooked.  I did test the heater of CRT for continuity ( it shows 3.2 Ohm ) but I have no other way of testing it - at lease that I'm aware of.  So I feel like I'm flying blind.  I really don't want to waste money destroying replacement parts.
