510 concerns.

[skinerd]

I have a bev 5900, it's identical to a DN 510. It has no resistor, only pads at R331.

Before completing the vid mod, I checked my connections and and power levels, just wanted to see where everything was at.

Before connecting 12 v to the vid mod switch, I positioned the switch so the wires from points A and B, (using the easy vid mod guide), were open. No 12v power wire connected yet.

What I found makes me wonder WTF. There is 3.3v on the center wire to the switch. It is connected correctly acording to the guide, this is not my first, by any means, 501/508/510.

This being the case, if I connect 12v to the switch, it will connect 12v to 3.3v, when switched on.

I thought after cutting the trace that wire should not have any power on it at all.

The other wire from the trace cut is at 1.6v, so I know the trace is cut.

I have been reading of seveal vid mod failures and ruined flash and CPU chips, and would like to get this resolved before I or anyone else ruins one too.

There are several vid mods guides available, and I can understand the confusion others have.

One of the guides shows a trace cut between the 2 flash chips, other guides don't show that cut.

Anyone else see the concerns here?

becareful sounds like one of the units i have here that was working fine unit i turned the vid mod on now i can get box keys but not into flash programming this was a 510 now its scrape, guess C$325 lost. even if the card came with programming guess expensive 120 gig drive and remote lol

Got it figured, need to cut the trace between the flash chips and use the method posted the uses 3 wires, 2 from below and one from R325.

what is that one? i have only used the one with wires from either side of the trace cut underneath and 12v from the power supply board

I have seen about 4 different 510 vid mod guides, w/R331 w/o R331 and a couple different versions of those.
I suggest you measure the volts on the connection point to the center of the switch BEFORE attaching the 12 wire, if you have 3.3v on the wire going to the center of the switch DON'T hook up the 12v until you fix that.

I have not had a problem with one yet.
But as luck would have it I am holding my personal 5900 in my hand .
LMAO
And I am not interested in ^&*^ing it up .
Thx for the heads up.
I am always in the habit of checking the voltage applied anyway , but still a good reminder.
