Hi all - new here: I opened up my URC MX 800 to clean, and once I put back together the screen test tells me the IRamp, IRout and light failed. True, the backlight doesn't work, don't know what the other two codes mean ( guessing IR code related?). All three checked ok before. There is a spring attached to the small board at the top which I'm guessing needs to make contact but not sure with what. Any help much appreciated. Attaching photo of this see spring at bottom and lights and led at top. Thx so much!
