I just got this tv 4 months ago and i came home from work one day and realized my tv wouldnt turn on. I hit power button and it sounded like a cd skipping sound. I then saw once the tv turned off by itself that the lamp light was red. So i bought a new lamp and it still won't show no picture. When i hit menu and input its coming up with code 12? What does code 12 mean? Mitsubishi won't cover it because it was bought brand new on ebay. Can anyone help?
