(and yes the playfield will be cleaned very soon haha)
Quoted from SUPERBEE:Just brutal!!
Yes it sucks, still trying to think of a way to 'repair' this or atleast cover it up..

Quoted from RobDutch:Playfield damaged a bit hmm..
Lets paint it green! [quoted image]
Turns out it was a sticker 
Have to be very gentle or else I will tear off all the paint.

Just got this WPC95 board to fix a weird hack/fix..
The capacitors both have a resistor on each of their wires.
So instead of just 2 capacitors, this hack/fix involves 4 capacitors of the wrong size, and 4 resistors 
Also because of the way they are placed, they are very very loose and move a lot..

Quoted from yaksplat:But, do they calculate out to the correct capacitance?
Capacitance yes, voltage no..
Soldering is also really bad so this is being taken out.
Quoted from Robotworkshop:Maybe they wanted a cap with more ESR so they added it externally?? I guess their motto was if we can't do it right we do it anyway.
My guess would be that the game broke down on location and they did not have the right parts. Instead of ordering/buying them somewhere, they decided to do this hack/repair because the game had to work again on the same day

Quoted from chad:Yikes, and no insulation anymore!
Indeed, taking this weird fix (?) out and putting a brand new PSU5 (with a more stable voltage then the original LM323K) in!
Quoted from Jahkub:The REAL tilt bob.
Tilt the game, break the boards 
As if the hobby is not expensive enough already hahaha
Quoted from Tuukka:Looks like someone has been out of LM323's and cleverly created an adjustable 5V regulator from an LM317.
Besides accidental shorting, it is really amazing if it ever worked without a heat sink and not go to thermal shutdown. The original LM323 is rated for 3A, and LM317 for 1.5A, which is just barely enough and even then with ample heat sinking. But of course that depends on how much the unregulated voltage is over 5 volts.
Clever idea sure, but if you are doing a hack (?) like this: make sure you don't short everything
I'm putting one of these in: https://www.flipperwinkel.nl/winkel/contents/nl/p7155.html
It should be a more stable version of the LM323

Quoted from Atari_Daze:I like the zip tie for good measure.
They drilled 2 big holes to get that zip tie in 
Had to be a tad creative because of those holes and missing traces, but it is fixed.
Now on to the female side, which is even a bigger mess..
Multiple wires soldered together, half burned connector left, etc.
Surprising it didn't short anything..

Who needs connectors anyway? Just solder all wires to the board and add some funky hacks! Make sure to cause a short so atleast one of the opto's will blow.
In all seriousness: who does things like these and why are they allowed near pinball machines? Found "awesome" solder jobs all over the game.. Luckily the boards in backbox are untouched, as far as I can tell at least..
