aidso Posted August 13, 2008 Share Posted August 13, 2008 Ok I know these units pretty well but im tired and have been working since 8 this morning and cant think. The problem is that channels 3+4 are not working. Im thinking its the resistor but want a second before I strip the whole board out as its the hard wired type so there is stuff on top. Check mains supply and its fine. P.S. This is urgent as I have them going out tomorrow. Link to comment Share on other sites More sharing options...
Andrew C Posted August 13, 2008 Share Posted August 13, 2008 How not working? Stuck ON is the power resistors (almost for sure). Link to comment Share on other sites More sharing options...

There's a whole lot of info already on this forum re this problem- and it's very easy to check the components concerned without stripping too much.I found the info very useful.
