For 6 blinks,Pls check following area.
Low HV Shutdown: On the D Board. Check IC8004/pin 7 should be 7.4v. Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on. Check IC8006/pin 3 reference voltage 2.2v. IC8006/pin 1 normally at 0v. If high turns D5007 ON which turns the latch circuit Q6532, Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.

Hi, I don't know the relationship that Cosco has with their customers however the best way to get the CORRECT model number is directly off of the back of the TV. The model number you have is not complete. It should have something like a "KVR" or at least something beginning with a K. Hope this helps, Best Regards, Mark
