😂 You've got me scared already but thanks for the advice,I'll see if I've got time to check these things tomorrow be prepared for more questions.🤣
-
Yeah I dont want to make you too afraid yet. It doesn't look to be that bad, You can easily test the condition of the board surface on the resistance test on your meter just put the probes 5mm apart in the damaged area. Nothing is a good reading. Have you checked the voltages from the power supply aswell to make sure the 12v (14v) is decent?
-
Thanks for the replies again much appreciated will check the resistor,MattyL hope it's not that as that's definitely above my pay grade if it's something like that, I've had pinball machines for years and fixed a few but when it comes to board work I'm useless. Cheers Brian
-
It also could be rotten power connector crimps or its shorting across the the corroded solder mask (if these are anything like scorpion 1).
-
Just use the Ohms setting on the meter, with no power applied of course.
-
Cheers midibob would I check it under power. Cheers Brian
-
Yep it supplies the 14v (ish) to the reg. So if there's only 1.2v getting to the reg the resistor would be dissipating a lot of power and very hot if not burnt out! It should be 2.7 Ohms 3 watt I think?
-
Did a wee check and see R14 is a resistor,midibob when you say glowing would you notice it straight away. Cheers Brian
-
Hi midibob thanks for replying,I'm a bit knew to this what is R14 on the board. Cheers Brian.
-
Is R14 OK? I would have thought it would glowing if you only measure 1.28v?
-
Another wee update,I checked the voltage regulator under power and I'm getting 1.28 on the input and 0.51 on output,I gather that isn't good and the voltage regulator is knackered. Cheers Brian

I hope you enjoy the machine Chris :))) you twisted my hand not to covert it back into exchanges
-
Can any one please help with all the t8 b4 and cat c games please for a t8 machine please this would be appreciated

Line Up Chris replied to Line Up Chris's topic in OLD FRUITY DISCUSSION
New in @chris217s😊 This was the machine that was subject to past conversation. I was looking for the name But now I own the machine. I thought this was a lost machine tbh. VFS Xtra Dividend. Runs on mpu3 tech and has jackpot upgraded to £4! (from £3) Still pays out jackpot in 10p tokens. Here is the video😊 -
Cheers Ronnie funnily enough I just watched that vid when I was searching what to do 😂
-
TTX started following A Few board Remakes
-
Amazing work Matty!
-
Brian watch this or you could put probes on pins 2 and 3 should read 5 volts when powered up
-
Hi Matty l thanks for the advice,how would I go about metering across the voltage regulator. Cheers Brian
- Last week
-
These old bell fruit boards are tough as nails because theres solder covering the copper which protects it. The green solder mask can go nasty and conductive though
-
Ive never worked on a system 85. It doesn't look too damaged. It does look like the voltage regulator is damaged though. Thats whats dropping the 12v supply to 5v for the board. I hope its just dead and not shorting. I wouldn't power it up again. It needs metering across the regulator really.
-
It was gave it a good clean,did a continuity test on the fuses that's when I found 2 holders were gubbed, one 5a was toast also thought I had a replacement in my pinball spare fuses but all to big so will get one tomorrow.
-
Don’t think they would stop the board doing something , how was the game card pins and the Rom chip and socket? The game card looks a bit crusty!
-
Here's the first one up and running for a few days. Ive still got to test it with the extra 2 Eproms and driving an LCD meter. Im sure my routing is all perfect though. As soon as the reels first twitched I was like thats all the processing and serial link sorted... then the memory alarm went off which validated all the audio (which theres alot of!). I was like wahoo! Nailed this one first time also. R.e.l.i.e.f 20260718_162233.mp4

Transplanting the Actel FPGA from an original board... not for the feint hearted!

Here's the first one about to get built up
