To the people with yellow lights on there Ps3's ,if you could not re-heat the boards you will save your self in the long run..

The boards actually need to be re-fluxed and then re-heated.

If you just re-heat them it will last a week or so maybe a month if you did a good job. but will fail again..

Get your Ps3 off to a good service agent (not Sony) and make sure you ask them if they re-flux the boards,, if not then go to one that does..

If you do it this way then your ps3 will work for years to come...
