thanks guys, i will probably go down the thicker monitor bracket route! wish me luck

Hey guys wondering if I could get your help/opinion

I bought a Dynamo HS5 without doing my due diligence, and now facing this issue.



My OCD is itching, let me hear your thoughts, can I use a wooden bracket around the monitor as a spacer? i do have some room in the front behind the glass, or would you leave it?

Hey I had a similar issue with my pole position, I was able to narrow it down to one of my AR II boards since one speaker worked well and the other didn't. I'm having a hard time finding the article but basically it told me the tda2002a on the AR board was bad and replacing it fixed it right up.

Congrats, that pole position cab looks great!

I would start off testing to see what voltages you are getting at both boards test points.

Hey Does anyone know where to grab a pole position coin door, i would be looking for the whole assembly, all i have is the doors itself. 

I have searched kijiji and only found the link below but he is not sure what game it came from and it is missing the wiring harness.

I have also searched eBay quite a bit but i want to be sure it will work for me before i spend the cash and get is shipped.

Post a picture if you can, it may help us see what you are working with.

Thank you Ian!, I successfully replaced the Transistor at Q4... this lead me to an RAM 0 Error on screen. after some more research looks like i have to replace an ram chip on the video board 8F i believe. luckily i ordered extra ram chips with my battery kit from Ian. but before replacing the chip since i dont have a good desoldering iron, i wanted to try cleaning the back of the board. it had a spongy type materials looks like it was supposed to separate the boards so they do not touch. any way i cleaned the area where the ram chip was. BINGO!!!! game booted up .

still haven't tested the game i need to rebuild my utility panel... also my coin mechs are missing, but im soo close :p

just an update on this, with the help of a local electronics repairman. we were able to find the short and replace the part. it was the Diode at cr2 in4735a i believe.

I have rebuilt one of arII board and am now getting 5.17 V from each board no load, when connected to the board i get 4.77/4.86 volts. getting both led lights on.

i was having an issue where the monitor was giving me a pink screen with "raster lines" (I believe its called), so I checked the video input. connections looked good, so i moved on to the dials on the fly back. i adjusted the screen dial and i got some video.

Unfortunately i am getting a Ram 8 Error. after doing some research it looks like this error may be coming from the part of the board that has to do with the battery. the old battery has been removed and there is definitely some corrosion in the area. looking more closely i see that Q4 one of the transistor legs is broken. i dont have enough of the leg to solder it back so ordering parts it goes..




Edit "Words"

Definitely a short, 5v+ beeps on a continuity test to ground. Something's wrong with the board.... Now trying to find out what. Can anyone tell me if a cap should beep when testing continuity over its leads on the board?

You are right thanks, it does seem like it is shorted somewhere. or I'm thinking a bad ground.. i will triple check the wiring harness, would anyone know if there is a good place to look on the board for this type of issue?

Hello, Brand new to this and i just picked up a pole position. obvioulsy the game will not turn on one of my AR II boards is bad and not putting out the correct voltage. but my other ar II board i believe is good, when i hook it up to my Video board i get the red led to come on, but when i connect it to my cpu board the led comes on but dims out with a second or two. when i have it connection to the video board i get around +5 volts connected and testing at the test point, when connected to the cpu board im at around 1.2 volts.. how screwed am i?
