Quoted from altan:L1 is da bomb and you'd be crazy to use anything else.

What's the difference? What makes L1 better?

Quoted from Rum-Z:My Dr. Who has this issue. I'm currently touching up the black around the inserts and I'm gonna try one of these Makrolon protector sheets from Bay Area Amusements to cover the touch-ups and protect that area. I'll see how that goes shortly.

They have been out of stock on that one forever. Do you know when it's coming In?

I'm wondering if someone in this club could help me out? I recently disassembled and reassembled my Dr. Who for a restore. When I put it back together it now keeps instantly blowing fuses F106 & F110 and giving me a message on the DMD "check switch mini opto 5 bank 71, check switch mini opto 5 bank 72, check switch mini opto 5 bank 74, check switch mini opto 5 bank 75". Does anyone know what I've done and how I can fix it? Thank you so much for your help.
Quoted from goingincirclez:The opto error messages are referring to the bank of 5 round targets in level 2 of the Time Expander. Off-hand I'm not sure if that correlates to your fuse issues or not.
As for the 5-bank, there are two optical LED sensor boards, each with 5 LEDs. One is the transmitter and the other is the receiver; the switches themselves break the signal between them. It's common for these to fail but often the fix is as simple as reflowing the solder on the LEDs (I've had to do this on mine). Curious that your #73 opto did not flag an error, so hopefully that's a sign that your boards and connections are good and you just need to dial-in the other sensors. Did you have all this apart when you restored your machine? Maybe some of the LEDs flexed and broke some cold (aged) solder joints.
If you didn't have it all apart then, removing the 5-bank for service is not terribly difficult, but it does take several minutes. You don't need to remove the entire time expander but you do need to be careful.
Thank you so much for the response! A quick update. I reflowed the solder to all the wires and optos on the 5 bank opto boards on the mini playfield and I still get the errors. It's actually switches 72, 73, 74, and 75
