I bought this tv fully knowing that it had the common only turns on from a cold boot 6 blinking lights. So I replaced the two MCZ3001D IC's on the D board. I first replaced the one closest to the tube transformer since it was easier to do. That still left me with the 6 blinking lights. So I replaced the other one. As soon as I plugged the tv in there was an audible pop sound ( no smoke or smell) that came from around that second MCZ3001D. There are no popped capacitors. There are no shorts in my solder joints. Now I have 3 blinking lights.
