I have some flickering on the upper (alphanumeric) display lines when I start the game. It mostly goes away after a couple of minutes...

I measured the power going to the display : -118V and +103.5V.
It should be -100V and +100V and was told to replace the Zener diodes 1N4764 100V by 1N4763 91V versions.
On the power board it's ZR2 & ZR4 on position 23 but 23 is not mentioned on the drawing.
Does anyone know which ones these are ?

2 questions,

1)
Are these sides stickers: launch (right) & diverters (left) still available somewhere ? Unfortunetly André Gagnon (designer) doesn't reply...

2)
I have 2 cables just hanging around... White/Violet. associated to a number of switches in the matrix but all switches seem to work fine...
Any idea how/where these should be connected to? or just to each other ?

Just near it I have 2 orange ones as well, soldered to each other...

Thx ! Strang thing is I only see 2 cables while on the drawing it should be 3 and 2 of these 3 should be bundled together... I'll Have a closer look but do you think bundling 2 is a must if I find the 3th one? And whcich 2 to bundle, will than be the next question

I have some issues on both my alphanumeric displays. (not on the bottom numeric ones)
I got some jitter during a couple of minutes, partial parts of the display are blinking/illuminated (see pics)
After a while it's gone ...

Swapped it for a partially defective Big guns display (only player 2 is still working and when used it on F14 I didn't have the issue on this alphanumeric display)

My logic says if it works fine on another display the main boards in the pinball are fine and problem must be on the display themselves or IC's processing and sending data to them on the display board..

It's like they (IC's or displays) needs to heat up a bit first...

I already got some good feedback from other pinside members (thx for that !!) but ideas were mainly focussed on possible pinball/backbox PCB problems as source of the issue. Which in my opinion doesn't seems to be the source based on what i just wrote....

Anyone some fresh ideas?

I ordered a set of insert decals at classicarcade on 05/19 but never got them !! Ebay just authorized a full refund.

I saw planetarypinball as them as well but saw posts saying the quality is not so good. Anyone has experience with these or knows another (better quality) source to get them ? (located in Europe but US is fine, if they ship it out )
