Help with Sony KDL60W855B

[Deutch1958]

Hi this is my first post so here goes, i have a tv and the problem started when it would power off after 10 - 20 minutes, i replaced the power board but still had the same problem so i replaced the a/v board and the tuner board, this lead to the screen having black and white squares then followed by horizontal couloured lines then followed by a white screen. I replaced the a/v board and tuner board again but still get the same issue please help.

Hi there,

It might be best to contact Sony support on this here.

Let us know how you get on.

Best wishes,

I have been in touch with Sony support  but they just say they can't help me.
