I sent my 1DS3 back, second time in eight months. The first one was the 99 cannot communicate with lens error.
This time it just wouldn't come on. I sent it 4-9 and got it back today, 4-21. Not bad.
Technical report says: PCB assembly inoperative. Replaced. They also made some adjustments to my in viewfinder right side EV indicator would jump around, up and down, before landing on the dialed setting. They said they fixed that too and did a complete check up and adjustment.
So what is the PCB assembly? Is it what I think it is, the cameras Main Board fried? I can't believe it. lol. I wonder what will be next, a battery explosion? I really hope I have enough money to buy the new 1DS4, AFTER it goes through testing for around six months. I'm afraid I can't rely on this thing anymore. You ahve to admit, this iteration of the 1DSxxx was plagued.
