I purchased the CORRECT power supply module from SPIN - installed and still no game ALL the led lights on the IO board are lit - there is power to the monitor - no bong sound - game is dead. What would be the most likely component to fail with an incorrect Power Supply? The fuses on the power supply back panel are good - the main fuse is good - all boards and connections are seated - no VISIBLE damage to any boards.

The MPU board. Do you have a 1.5 or a 1.5+? (the 1.5 has a daughter card where the vga plug is). I would just get a 1.5+ even if had a 1.5 previously. More relieable in my opinion.

has the daughter board - would that be the board that most likely would fail - whereas the IO board indicates no power (all the led lights are lit)?

It has been a while since the my 550 cabinet has run legacy, but I believe all the led lights on the I/O board should be lit? I would have to retrofit my 550 cabinet back to legacy to test. Hopefully somebody else will chime and and verify, if not, I will re-convert my 550 back to legacy to see what it list and what is not. If the power module had the wrong voltages (i.e. 12 volts where 5 volts should have been), it would have blown the mpu board for sure. I would try that first.

i read somewhere that there are VOLTAGE lights and a FAIL light - with the voltage indicating voltages are good - obviously the FAIL means problem. So with ALL the led lit - I assume I have all the voltages BUT something? FAILED. I see the IO boards are available for a reasonable amount - do I TRY that first or is the FAIL an indication the MPU is as fault.

Hoppers are usually 24 volt. When you power on the game do you get lights as well? Is the BV still not getting power? What about any power LEDS on the backplane?

I don't believe the Fail light would report the MPU, but only the I/O board. I would just get a set of I/O and MPU board, always good to have spares, especially in these older platforms.

would like to try to narrow down the problem - buying boards not knowing if they are good as well - just would like to see what the led lights are telling me.

Hopefully somebody who has an active 550 machine will chime in. If not, I will convert mine back. It's been like 6 years since I've run a legacy game on my cabinet since I switched to CPUNXT.

i appreciate your offer - but lets see if someone chimes in - save you all that work - and me spending money for nothing.

See if this helps any.
Not for your particular error, but then again.
Check and re-seat all PLCC chips and check for properly seated EPROMs

See PM

got my boards repaired by SPIN - now I get the chime and message "invalid ram clear" ?

rickhunter · « **Reply #32 on:** February 05, 2016, 10:14:00 AM »

Did you clear the game after you got the boards back? Check voltage on the battery.

GOS · « **Reply #33 on:** February 05, 2016, 10:30:00 AM »

how do i clear? chip? battery is good.

rickhunter · « **Reply #34 on:** February 05, 2016, 10:45:49 AM »

Yes, you need a clear chip. I'm not sure if the universal clear works for non 1.5+ boards. You will need one with the denomination you are using as that is how it worked originally. What denom do you have on your cabinet?

GOS · « **Reply #35 on:** February 05, 2016, 10:51:31 AM »

i think i have a clear chip in my files - need to bring up my pc and check - I have some clear instructions - says for model 40x - mentions an xu2 - my game is 5c. My game is the 1.5 has the daughter board.

rickhunter · « **Reply #36 on:** February 05, 2016, 10:57:47 AM »

If memory serves me right XU3 is where the clear goes. Someone else can verify this for us, but I'm 99% sure it is XU3 as some of my 550 mpu's actually came with a zif socket in XU3.

Did Spin say if they found problems with both boards or just one?

GOS · « **Reply #38 on:** February 09, 2016, 02:44:25 PM »

I need a multi denomination clear chip for williams video - i have one but it is for the slot.

GOS · « **Reply #39 on:** February 15, 2016, 12:03:22 PM »

got a multi-denomination clear chip as recommended by tech at SPIN - copies onto a 27c080 eprom (cksum d04f) - installed and "SECURE MEMORY FAILURE" put game chip back and no gong.
