Had been having issues with my Paragon booting up, which i had assumed was my rectifier board. I had this tested and repaired and once re-installed it was working ok again.

I had many globes blown however, so i replaced with new globes. This process went fine and when completed i pulled the PF down and back to reseat into the cabinet - when the game and lights dropped out. The the majoirty of the PF lights went also - The GI's remain working.

I reset the game and it would still not boot. I checked the CPU board test flasher and am getting 1 flash, followed by a small pause with 5 more - 6 in total. I have re-seated all the connectors & also checked the fuses which all look ok. Not sure what is stopping the final flash & game to boot, can anyone advise a suggestion.

Also, a small side question - many of the lights i replaced will work but then drop out. I have wiggled them and the connector around & they will go again, but will drop out. Clearly there is a connection issue between the globe and socket - but i really dont know how to fix this from being a constant problem .Does anyone have any tops on the best way to avoid this happening, especially with older, less kept machines.

Thanks in advance

An update folks

removed all fuses on PF & rect board and all tested ok.

Disconnected the sound board as read that can be an issue.

removed all connectors on all boards, one by one, to see is i could get it to boot. Then re-seated them.

No change.

Based on this is it likely a resistor on one of the boards? I am not very skilled with board issues. Which resistor should i be looking at and how would be the best way to test?

Hi im not sure what this exactly involves & the attached link is "outdated".

Ive already removed fuse F4 & tested it & it was fine. Do u mean its possibly the fuse holder?

With U10 & U14, are these on the mpu board? If so, How doi test them?

Sorry, board stuff i am not quiet there.

Hmm, i think it must be on the rectifer board still. Only getting a reading of 1v. So does this discount it being a connecter on the rect.board?

If someone can direct me to what needs attention,
Im willing to have a crack at repairing components on it. have the day off so might as well & need to learn sometime

Thanks will do the test for educational purposes but agree - it needs a new board. I have chased tail on this one.

To confirm power on machine, change to AC on multi-V, - to + & + to ACs on BR3?

SoLVED: when testing the BR3, when pushing prod onto AC point the game booted up. When removed though, progress ceased. I reflowed the solder on that AC point & the machine worked without issue.

Will still invest in a new rect board at some point, but glad to have her purring again. Thanks mate, massive help
