HP 3581A LED digits not lighting
Hi,
I have a 3581A that was working a few years ago when I purchased it off eBay (yes, yes, I know). I went to power it up recently (not having powered it up for about a year) when I noticed that the inner two LED digits are not lighting. I'm not talking about missing segments, but the inner digits not working altogether: http://img706.imageshack.us/img706/5645/3581aled.jpg Working the frequency control I can see the lighted digits changing, but that's all. Is this a repair that is straightforward? I consider myself handy. Otherwise, any tips/advice on where to have this thing sent for repair? Thanks, Chris |

Thanks, Chris Can't be much.. most likely a cable header connection. |

Try moving the cabke in and out slightly at each end. Then dig into the 170 pages of the manual. |
