long story short: My xbox loads up, runs fine for a bit, then goes "KZZZZT!", a frozen pixellated picture occurs and on reboot i see the RROD. Apparently I've overheated it and my repair shop says they can fix it but it'll only be temporary.
My question is: "Is this true, or are they trying to sell me another xbox unneccesarily?"
Note: I may have opened my xbox to clean it afterward (Loads of dust build-up!) thus voiding my warranty and its a 1st gen anyway....
RROD sucks, I've fixed a few for friends before using various methods and a couple of them are still working whilst others are not, repair shop are telling the truth, and no, ITS NOT YOUR FAULT IT OVERHEATED. it had nothing to do with you, its a common problem so dont let anyone say its your doing that caused overheating!
1. Sell your RROD box on ebay, console only (keep everything else). You should be able to get $50 for it
2. Buy a working console-only 360 on ebay. You should be able to get one for under $100 (I got mine for $80)
