Always seem to run into wierd crap when I'm working on my own stuff. Todays cluster f**K is my own Crestron TPS-6000 wall mounted touch screen.
It has been working fine since installation. I needed to add a couple of buttons to the user interface. When done, I uploaded the new design to the screen as normal. At the end of the upload the touch screen rebooted as usual then died WTF. I did not have the time to look at it at that time so I unplugged the power/signal cable from it until I could look at it later. Over the weekend I pulled it from the wall so I could play detective. Couldn't find anything. I plugged it back in and it powered right up. So I put it back in place and it has worked fine for a couple of weeks. A couple of nights ago I had to power down the automation system for some rack maintainence. When I powered it back up, all the touch screens came back to life but that one. OK, back in detective mode cause it's dead. I think what I'm seeing is a surface mount PTC fuse that is not resetting. It is a small black device with one input and one output.
It has no name on it. There is a white line in the input side followed by a 33 over what looks like a A. I have 24 VDC going into it and nothing coming out.
I have 1,2 and 3 amp automotive type fuses here so I am going to try and jump it with a 1A first to see if it powers up. Wish me luck. These large Crestron
touch screens are wicked expensive and I don't wish to blow it.
