Hello,

Having some issues with Tron Pro.

Seems 'BRDG1' on the Power Driver Board has failed.

It's a 520-5249-00 Rev A board.

Does anyone know the spec of this BR please? Other BR's on the same board are labelled, but this one only says "DIOTEC".

I have a new BR from a UK parts supplier, shown in my hand, but before i make the commitment to swap it out, i would like to be double-super sure it's the right part.

The game keeps blowing F5 - 48VAC, and also went through a few cabinet fuses too - but only as soon as the coin door is closed... ?

Weirdly, it's showing some faint LEDs on the fuses when the coin door is open.

Any thoughts appreciated! I've checked for obvious shorts etc. HUO game.

What does your manual say? Also what makes you think its the BR that is dead?

The SAM manual calls it a DB3501 bridge rectifier, same as the other 2 BRs on the board. Looking at Marcos page it looks like you have the correct replacement.
