I have made a terrible mistake for which I deserve all of the ridicule that I am sure is coming. Today, I installed a 6116 ram adapter in the wrong board position. It was supposed to be installed in the U25 board position, but I mistakingly installed it in the U23 board position, because they both contain a 6116 ram. So, as I see things, I need to procure a Hyundai hy6116ap-108905A chip and holder to resolve the situation. My question is, if this is an easy problem to resolve? Where do I get one, and does it need programming? Are there any unforseen repercussions for my error? Any help would be greatly appreciated. Let the beatings begin! Thank you, Todd

Thank you very much! I appreciate the help.

Today I installed my board with the new 24 pin chip from action pinball. I am wondering if that chip needed to be programmed. I am missing about half of the sound now. I am still working to find the problem as we speak, but was wondering if anyone had any wisdom for me. Thanks.

Yes 6116. I am taking a picture now. U23 position. As you see when I originated the thread it was a result of my mistake in attempting to alleviate the battery backup problem -ADJUST FAILURE- I replaced the U23 when I should have replaced the U25. They were both 6116. Pic coming shortly.

I identified the u23 and the u25 in the pic with wire marking stickers.

I am missing the female voice that says "looks like rain" and the multi ball speech prompt that says "feel the power of the wind" . My wife found a similar post that was implying that the j3 connection on the sound board may be suspect, so I am now investigating that. In the last half hour I have been getting partial sounds of which I have been missing ,but they are full of static , so I am suspecting a bad connection/ground. I am investigating that now.

I have re seated and checked all connections. I have checked every braided ground throughout the main cabinet and back box. Just rewired the electrical cord because it was loose at the plug. Trying to consider all possible causes, big or small.

I'll get a picture of the battery holder this afternoon, and post it.

When I got home from work I just turned it on and tried it and it worked flawlessly for 3 games. The fourth game it started to fail again. I have re seated plugs and ribbon cables as suggested, and checked/tightened all grounds. When I mess around with J1/J2 plugs I can sometimes get it to work. Feels like a connection issue. I am redoing the J1 plug wires to see what happens. Thank you.

The problem all started with my effort to eliminate the need for batteries' (besides the "adjust failure" message), hence why I started the thread.

Thanks Mitchell. I am going to heed all advice and move forward. Thanks to all.

Thank you PBM 40 I could not figure this out without help from people like you.

I am just puzzled as to why when I leave it alone for a period of time, it will work a few times and then fail again. There has to be some wisdom to take from that???

Thank you PBM 40. I am going to take the board back out now. I'll keep you posted.

I am perplexed though. I leave it alone overnight and I get 3 perfect games. I post on pinside for 30 minutes and I go back into the basement and get 1 good game. I understand connection issues, but doesn't this maybe suggest a voltage or other connection issue???

I think that resolving my issue will come from my observations, resulting in asking the right questions. The right questions prompt knowledgeable people to dig deep to make an educated suggestion. Some don't read the thread from its infancy, and suggest short sighted possibilities. Thank you to all that are more detail oriented! Just an observation, as I am new to this.

I took all suggestions. Cleaned slight corrosion from board, re soldered j1, checked sound chips with lighted magnifying arm. And again. Got home put board in, played exactly 3 games and it failed again. This pin worked perfectly 9 days ago. After the 6116 change, I have created an issue. I don't want to puss out, but I am about ready to purchase a replacement board. Are they readily available?

Why is it that I can play 3 perfect games with no issues after letting it sit for 12 hours, and then the problem resurfaces. Again this was all after removing the main board. It worked perfectly 9 days ago?

I just don't understand. It worked 9 days ago. I'm not saying your wrong, but in my mind why open a new can of worms to adress a sub-standard condition that existed when I removed the board. I'm just trying to remain focused on variables pertinent to what I have just disrupted by removing the board. I worked to remove all corrosion as suggested, but I am trying to keep a focus on what it is that JUST changed. If I chase preexisting conditions and create a new problem, then even if I inadvertently fix the original problem, I may be creating new ones. Thanks. This is good dialogue. I am ordering a new battery holder.

I understand PBM40. Just hoping for a little luck this evening. I will do my due diligence. Thanks.

Alrighty! Removed board, checked continuity for all header pins, and all 4 sound chips on the main board. Also removed battery holder. As I feared, not only does it still have the original issues, but now I have brand new problems!!!! I am getting the status error prompt, and am receiving about a dozen playfield errors. Right ramp error etc, etc, and the list goes on. WTF???? Any wisdom would be greatly appreciated. Attaching photo of what lied under battery holder.

PBM40 I went through the entire thread again and realized that there were suggestions from you that I have not carried through. Will continue to work toward a full resolution. Thank you again.

Point well taken Mitch. I am sending it for repair. Thank you.

Very good PBM40. Thank you. Todd

Does anyone have a suggestion as to who I should send the board to for repair? Thank you.

Thank you for the advice.

I talked to Clay Harrell this morning just after I posted for your help, and he referred me to Jerry Clause.

I am going to drop it and the auxillary sound board off to his shop on Friday.

Thanks to all for your help, and thank you for being patient with me.

I heeded all of the advice that I could, but knew that I was getting over my head!
