I'm not sure why you're unable to reply, but if the set is not powering up at all, and it was after you heard the TV "POP", then this indicates a hardware failure has occurred in the set in most cases. Generally the regulator IC's or the high voltage circuit has failed and requires repairs.
However it's worth it to try a hard reset, as sometimes the processor in the TV can simply have locked up.
The first thing you would try, is disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 10 seconds and release. Then plug the set back in, and also check that the power cord is connected tight at the TV as well. Press power once, and see if the set powers up normally. Try this procedure up to 2 times to see if you get any response from the set.
If it still does not work beyond that, then you're looking at an internal hardware failure that requires repairs made to the set. This is an older Sony CRT (tube TV) and it is not cost effective to repair this older 19" tube TV - with repairs being on average between $150-$250 parts and labor.
A brand new 19" LED TV can be purchased for less than repairing this TV (from Wal-Mart or Best Buy) and is money much better spent.
Other than that, I'm sorry for the bad news here and wish there were a quick fix.
