Sony kv40xbr800 seven blink question

[duckland 23]

My television will work fine them for maybe two weeks or so shut off and sometimes turn back on again . Nut before she will shut down the screen will turn kind of pink with no video and then shut down . Sometimes before it happens it will look messed up like the color out of tune . I do get seven blinks when she will shut off . I bought the OEM Sony chips MCZ3001D NOT DB . Im wondering if I also have a problem with the guns on the set shorting out Just wondering what kind of problems sony television can produce .
