Re posting an unanswered and now archived question with new heading in hope of help....

Bought a PS4 from a Christmas church top fund raising car boot in UK

Box was sealed and I paid £480.00 but when I have set it up I get the blue light issue. I did get a phone number from the guy I bought from but on trying it, it does not exist. Tried all the solutions listed by Sony but no joy so called Sony customer support in the UK who will do nothing because I do not have the original receipt – very bad show!

Anyone know any fix for this blue light issue?

Is it the processor/solder problem like the YLOD/RLOD?

Many thanks Dan
