It sounds like a capacitor blew in one of the internal circuit boards. A capacitor makes the pop you described, and techs actually refere to them as "being popped".
You had a surface mounted capacitor (AKA "CAP") let go on one of the circuit boards, open the set up and look for a small burnt area on the circuit boards inside the TV, it is likely it will be the power supply board, but that is just a guess..
no really, I am just a smart a$$ --- but the loud pop sounds like it may have been one of the capacitors in the power supply board. check for a POPPED cap (rare) and if there is one, test the components in the related circuit - as SOMETHING had to happen to make a cap fail like that - maybe a voltage regulator? give it a look..
Process of elimination with a volt meter. Plus when I removed the lamp cover glass went everywhere so that pretty much told me the lamp was toast. Thanks for your response.
