The loud pop was a capacitor blowing up or the high voltage transformer blew up. Very common problem.. if its the Transformer be expected to pay 250 or more to have repaired.

You need to replace the lamp in this set. The "pop" you heard was the lamp popping.

I have the same TV and had the same problems. What worked for me. I tuned off the set unbluged the TV, waited about five minutes and replugged and resolved my problem. Hope this works for you.

Sounds like the DLP lamp failed. You can decipher the Hitachi flashing red light. That should help to be sure.
The DLP lamp replacement is fairly straightforward and can be done with minimal tools
