Well just over a month old and the ac/dc led display has a permanent column turned on. A warranty replacement is on the way, but does anyone know anything about correcting this fault. Ive read before about conducting compounds used on older type displays bridging breaks??
re seating the ribbon hasnt cured it.
A top game, but failing so soon :rant:
 
Ahh dude that's poor those displays never quite look right ,not sure on a fix but hope stern pull their finger out and sort it or ya!!!
 
That is sad to hear. If the column is on then it sounds like it is shorting rather than a broken leg.
I used this conductive glue to fix a broken leg on my TAF: http://www.ebay.co.uk/itm/1-x-ELECT...Scrapbooking_Glue_Tape_EH&hash=item45ff034c89
First attempt was a mess, so I cleaned up the leg, added some solder to give a great surface and tried again. Worked well and held when I moved the machine too.

Do you get to keep the old display? Might be worth a play with. :attention:
 
Phil, from PBH has been great, only contacted him this morning and a new one is on order. Pudsey I quite like the look of the display actually the red led seems to work well with the acdc colours. As with anything you buy nowadays nothing is built to last. Some things fail hours after being turned on.
I wont be able to have a go at fixing it as under the warranty I have to send it back, else the scalpel and stethoscope would of been out to hopefully create a spare.
 
Thats 2 people I know bought NIB AC/DC Premiums (same container load I think) and both have had problems, your bad display and another with a dodgy cannon motor....not what you want when you've just shelled out £6K :doh:
 
Funny you should mention the canon. Mine stopped working, right in the middle of multi ball. I ran a test and its worked ever since?? I put it down to newness. Im hoping that nothing else is going to go wrong.

Ouch dude, Glad your getting it sorted though :-).
 
Suppose after 7 months I've had a better run than most...

Anyway, emailed Phil at PH and got an immediate reply to sort it under warranty. First class. :thumbs:
 
That's a sh*tter John, I take it it's still in warranty.
Once it's been replaced go for a Dr Pinball multi colour and put the Stern replacement away.
 
Those particular LED panels are utter garbage. I've had several of them die prematurely. The longest lasting of them all was one from PinLed, but that eventually gave up the ghost after a year. Like others have said, Dr.pinball LCD-DMD for the win.
 
Pretty much all LED DMD's have this problem, according to some googling, PINLED are some of the worst.

Guess what one of the most common causes of dead lines on LED DMD's is?

Lead free solder + surface mount components + high vibration environment = fractured solder joints


Line stuck on, usually = driver with floating input, or leaky junction on driver
Line missing = floating driver output or failed driver
 
I had a vertical line like that on my AC /DC for a while. One day it just went and the display was perfect again. Strange :hmm: probably a bad solder joint on the display that has fixed itself.
 
My acdc vertical line after 1 month. Excellent turnaround on warranty tho from phil and electrocoin. These displays aint cheap either
 
Man that sucks, Stern must be using some cheap ass china crap.

Stern are using all Vishay are they not?

If they were Won Hung Lo branded cheap Chinese boards then they would probably be more reliable, as Chinese manufacturers still use lead based solder by default unless you specifically request they not do so. The factories I have used for PCB's charge as much as 250% extra for ROHS compliant lead free based production as opposed to their default lead based.

Couldn't agree more. They were the best by miles.
I'm still dreaming of WMS pinball division kicking back up and showing everyone how to make the best machines in the world.
How good would that be.:clap:

This is some crazy Ju Ju. My washine machine packed up a few days ago too. Now, it works better than new? I do have some very smart cats but the lack of opposable thumbs rules them out. :rofl:
