I have just experienced the Solid Red Light on the XBox 360 S, and unfortunately my warranty finished 6th November 2013.
I purchased this unit for the purpose of playing movies and watchin TV from my Microsoft Media Centre. This is not the main unit in the house, so if used rarely, and I would guess that the unit has been operating for a maximum of 100 hours in total. The longest the unit would have been on in any single sitting would be 4-6 hours.
The unit is well ventilated and not closed in a cupboard but on a shelf, and is even propped up to allow greater airflow through the vents. I have had RROD errors on the previous model of Xbox 360, so am aware of the overheating issues.
When I spoke to support I was advised this is a “common” heat related issue.
Has anyone else experienced this error?
If the unit’s heatsink, or cooling system are insufficient to prevent the GPU or CPU from failing under normal operating conditions, then surely this is a design fault and should be replaced under warranty or the system recalled.
Unfortunately I am going to have to pay the $115 and send the unit in for "servicing/replacement" but it does sound like the old melting solder issue has not been resolved in the 360S.
