How to fix RCX 1.0 I.R. problem?

The LEGO RCX 1.0 powers ON and all built-in programs work well. But when I tried downloading or even communicating with the I.R. Tower, the RCX wont respond! =(

Which component should be replaced or re-soldered? Please anyone... help pls. I just need to know.. which hardware component is at fault... so I can fix it.

Thank you =)

hello, i have the same problem like sirgilberts.

My RCX 2.0 shows a icon for IR detection and my older RXC 1.0 doesnt react - i have three of them but they wont work.


I'm working in a Schoolboard and i have 6 RCX 1.0 bricks with the same problem. I am interested if someone finds a solution.

it sounds like it may be a software problem, make sure you're up to date with any drivers for your console
