Blue dots in middle of screen on our Sony 50 inch TV Model number KDF50WE655 How do we fix it?


I have found 3 possible solutions. 1 replace the lamp. 2 check the LVDS cables. these are like computer monitor type cables inside that go from main board to optical cables. I would reseat these before i replaced them. if nether of these work then i would suspect the optical block... essiticaly all the lens and optics in thes set. this is the most expensive part in the set around 800 dollars. this is usally the problem i have seen a couple at the shop with this problem..
