It's actually pretty easy to fix. I was getting the 0410 error the other day as well, so I pulled mine and found that the first relay had alot of carbon build up on it. I used the dollar bill trick(use a fresh clean brand new dollar bill, and run it between the contacts of the relay and it will pull the carbon off without damaging the contacts). Although some RCMs also require some re-soldering work, luckily mine didn't(I am familiar with doing soldering work so was able to make that determination). The other option if you are not comfortable with doing soldering work, is to try and take it to a TV replace shop(they are becoming few and far between), they are usually very experienced in doing soldering work, and most of them will do it for ALOT less then it would cost to buy a new RCM unit. Also there is in that other post the mentioning of the part number for the relays, I looked them up about a week ago, the relays themselves only cost about 3-4 bucks a piece(and there are 5 or 6 on the board), if you decide to take it to a TV repair place, I bet they could replace those for you as well if they are damaged.
