Something is going on here above the main issue. 5.5v is unheard of is it not? I've never come across a machine reading even up to 5.1v.

I think you may have a board issue above the typical reset fixes.

I still think something not typical is happening here. It *sounds* like someone did a funky mod to really overcompensate for a low 5v, and tied into something else and brought it up too much. If something screwy like this is happening, anything could be possible, depending.

I'm thinking there is a resistor somewhere jumping into the 5v to bump it up.

Always a problematic connector, but there is still an underlying issue here that I think should be addressed first before attempting any common reset fixes. All high and low 5v ranges should be only within tenths to hundredths of a 5.00, in fact, in my experience, I can’t even say I’ve seen or heard of a 5v over 5.15v or so. Even on systems such as Whitestar where you can adjust a 5v pot, it will only get you maybe a tenth of a volt above the 5v max.

When I see something very oddball and suspect such as this, I throw the current surface issue out for the time being, and try to get to the root of the more unusual problem, as I’m guessing this could be stressing or causing all kinds of other issues elsewhere to in turn cause a reset. You never know, maybe it could come down to a bad bridge or something typical, but I would trace that 5v back until you can determine what is bringing it up that high first.

Maybe post some photos of the board and the hacks you noted, if you have it out. I’m quite interested in what is happening here. I wonder if someone ties some desperate hacks, couldn’t get it to work, and just ditched the project.

You had a voltage of 5.5v??
