Answer to: touch screen not working (even after replaced screen/digitizer)Havent got an answer unfortunately, just replying to say I am in exactly the same position. New digitizer same as the old one, no response at all. Tried all hard resets and restores too. Used a compressor to blow out the socket, nothing. To me its pointing towards a logic board problem, which is obviously not going to be a cheap fix.
Answer to: The fans running high issue, again!Finally solved it, I can confirm that the above error code does indeed relate to the PSU temperature sensor. I have replaced the PSU and the fan is finally behaving itself.
