Hopefully you didn’t pay to send it back (never mind just read its warranty)… you can fix it at home for very cheap… under $10. I have fixed close to 30 RROD xboxes… and have only had 2 have the problem come back, which ended up being an E74 error which is basically the ok to throw it in the garbage.
PM me about iXtreme 1.6 flashing if you’d like 
Yup E74… throw it off a bridge
ALL you guys need to get your boxes flashed… unless you like paying for games :dunno:
Yup the new 65nm chip runs a lot cooler… def the unit you want to get, when you go buy a new 360, there is a hole in the box by the serial number so the clerk can read it without opening the box, right under the serial number is the volt rating… you can see it without opening the box, the Jaspers will read 12.1v on it… if it reads 14.1 or 16.1 DO NOT BUY IT… its the older model.
Yes you can mod the new lite-on, you just need to fill in the PCB info, etc manually instead of it getting it from the probe like the 1st gen LiteOn.
There is nothing physically needed to mod the 79
Correct…
Put some ass into the video connector… thats your problem… your box is still find n dandy.
