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 .

Turning pink may be the CRT getting an H-K short.
Best test is light tapping of the neck while running to
see if you can trigger it. If it does look for bad PC cons
on the CRT board also. A shorting red output can also
do it, just swap with the G or B output to test.
Beyond that you will need manual & equipment.
