DOUT voltage issue

[Echopraxia]

Hi every body,

I have some concern with my DOUT4 board. I am trouble shooting it for my MBFM and on one shift register (J4) I am getting odd voltages on two pins (3.6v and 1.6v). When I pull the register out I checked the voltages and was getting 4.8v so I tried another shift register and got the same 3.6 and 1.6 voltages when inserted. I looked at the DOUT schematic and saw that only 2 pins are supposed to get 5v but on my board I am getting 4.8v in at least 4-6 places. Can any one tell me if this is normal? I am using a 9vDC 400ma to power a MBFM with full control surface. 4.8v is what I am getting across all active pins on all shift registers. Reason why I ask all of this is because I cannot get my MBFM matrix working which requires that 4 DIN buttons get connected to the DOUT board.

Regards,

one shift register (J4)

J4 is not a shift register. Which one do you mean?

I checked the voltages and was getting 4.8v

Where?

Where?

Give us some more info ;) Decent pictures could help as well. Is this a regular DOUT module or have you already done any mods for the matrix or the likes?
