I have owned this model for several years, it was non functional when I bought it for 10 dollars but became a nice machine (my only one for a couple years).
Quite by accident, my daughter who is 13 now broke it (when she was 7) in spite of many attempts I have never been able to repair it.
I was reorganizing the entertainment center and had placed the Roberts on the floor (with the cover On for extra protection).
While helping me she tried to step over it from behind but bumped it (it seems very front heavy) and knocked it over on it's face on the carpeted floor. I wasn't overly concerned at that moment as it did have the cover on and the event seemed harmless but later found it completely dead (as in no power) and unresponsive.
I have opened it several times over the years (never giving up) but had no print or manuals.
I intend to try again and would like to hear from anyone with an idea that could help. I repair electronics as a sideline so I know how to fix things but the Roberts is so tightly packed inside that it's difficult to even check the obvious areas plus I work on it on the kitchen table so it has to be completely back together and put away in about 3 hours tops. I'm sure the problem is insignificant and will make me laugh when I finally find it but I'm not laughing right now. Any help would be appreciated, thanks.

re: x-1810D

I found a GX-1810D at the trash that was dead also. When I opened it I found the on/off switch to be broken. It is a snap switch, with a mechanical tumbler inside. Through an impact I assume it broke off and did not work anymore. I tried to find the switch on ebay but could not find it, so I simply bypassed it. Now it comes on when I plug it in, but it works.
