I know what the replacement was for the original Sega/Whitestar driver board for the low voltage dropout.

But I have a new Rottendog Sega/Stern SDB004 Whitestar driver board. This one has LED's on the voltages and those are all lit up. I even tested it and the voltages are where they should be...

However when my Sega X-Files runs for a few hours, it will start to drop out. A simple on/off won't do it. But when it sits for a few hours, everything is fine again.

Any idea on what is causing this? Something on the MPU / Driver board heating up and causing the Low Voltage and the dropout? I haven't completely tested the CPU, but I just did a quick look at it and nothing looked like there was any heat damage. Again, works great for awhile then boom....resetting like crazy.

Any thoughts appreciated.

I can not help on why the rottendog whitestar board shuts off on you every few hours. I can tell you I just got one today in the mail for my whitestar Sharkey's Shootout and it is junk! The one I purchased turns off about every 3 to 5 minutes. I also called about it and was told to replug the connectors several times, so I tried this silly concept about 80 times, over approx. 3 hours over and over to no avail.. I have to say I am beyond perturbed with this crappy board, so I put the stern board back in, works like a champ, never shuts off when it is supposed to be on. I bought this so called replacement board because it seemed a viable solution to my transistor problem on a few of the under playfield flash lamps that were staying on. I absolutely wish I would have just used the 280 with shipping to just fix the stern board! I am sorry you have one of these junk boards as I now have! So my advice, fix the original board and trash that rottenjunk board!

Just to update, I talked to Jim Knight, very helpful.

It was very simple. It wasn't actually a LDO. It was the connection from MPU to Driver board...a little cleaning of the connectors and the game works fine!

He said when the connection is bad it acts like a LDO, but it is just the MPU not fully communicating with Driver board.
