Hi everyone, I too like fixing stuff rather than chucking it away. I also believe that modern electronics are built to fail, that's why I like older cars!!
Anyway I have been following this tread since before Christmas and thought "well it seems that easy that I'll just get the power supply". That arrived last week and following SixerFixer's instructions I got it all done. I thought that it had worked as I saw the power light on the bench but after putting it back in it place..... nothing. It's a bar 48.
So my original board had NO power to it at all after testing (240v was there) no 24v no 5v. With the new power supply that I sourced from ebay the power is there for about 2 secs. The 24v is fine the 5v will only stay on initially then drops to 2,3v. I f disconnect the 5v then power remains at 5v as soon as I reconnect it it drops to 2.3v. This is telling me that something else has failed but I have no idea what. Can someone point me to what it could be? I don't really understand electronics, I do known how to solder well and follow instructions though! When I was a teenager (Mid 1970's) I worked for Orange Music(UK) wiring speakers and amplifiers. Thanks in advance.
