Wy dosmy ps3 turns green 1 sec turns yellow den blincks red

What you are referring to is called the Yellow Light of Death (YLOD). This indicates a general hardware failure normally due to overheating. When these PS3's were produced Sony decided to use lead free solder. The problem with lead free solder is that it is not as flexible as leaded solder but it is cheaper and more environmentally friendly. When the console gets hot and cools down hairline cracks appear within these solder joints and a good electrical contact cannot be made. This then causes the console to fail. It could be on a number of different components including the CPU, GPU or memory. There is a temporary cure that may or may not work but ultimately the console will need to be repaired professionally or replaced. As it is out of warranty Sony will not replace it but will offer a refurbished unit for around £130. If you look on Youtube for Yellow light of death fix there is a way that you can re-heat the solder joints using a heat gun but if you are not confident taking apart electrical items then this really may not be something you want to try.

I am sorry I cant give you any better news but unfortunately it is a very common problem with the PS3.

Hope this helps and thank you for using FixYa
