Hi. I am new to the forum. I have an old Dolly pinball machine (1978 I believe) that has been sitting in my basement for around 20 years. I had attempted to get it working around 10 years ago but gave up on it at that time. At that time I recall when I ran through the self-test routine it never made it all the way through the initial 7 flashes successfully. That's when I stopped working on it. Yesterday, however, I decided to try and get it working again. When I tried running it through the same routine I noticed no flashes or lights on the MPU module A4 and an immediate engagement of the right side bumper solenoid on the playfield (see picture below). The solenoid remained engaged with power on and I could smell something appearing to get hot up in the top section, so I shut it off. The game has it's original boards in it. I have a GAME 1162-E Service Manual (FO 635), and a Bally Electronic Pinball Games Repair Procedures - Module & Component Replacement manual (F.O. 560-1). Looking for some guidance in getting this back in working order again. I am open to replacing the boards, as I know they are likely in bad shape and certainly outdated. Any help would be greatly appreciated.

Included are pictures of the solenoid referenced above along with the boards in the backboard section.

Machine: Dolly made by Bally
Year: I believe 1978
Model: Dolly Parton Electronic
Serial No.: 5908

Thanks. Sorry. Will try the Solid State. I thought this was the correct one but guessed wrong. It did say in the Electro-Mechanical / EC Pinball Tech section that "If you have a problem with your pinball machine start a thread in this section. The tech crew will be with you shortly." Thanks for you guidance. Much appreciated.

Thanks.

Great. Thank you.

Thanks. I'm a little reluctant to have my board(s) repaired since they are so old and I feel they would continue to be problematic, so definitely leaning towards board upgrade. I will check out the altek boards, but there are several boards in my machine. Are you referring to just the MPU (A4) board or others? And is it just a matter of swapping to a new state of the art board or is there an upgrade package/procedure I need to be consider?

Thanks. That's an excellent price. I'll get that board and go from there.
