Loud pop in my tv and was wondering what it would be?
Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Non working TV, can someone help???
Replace Q8023 (top224y) which you will find is blown apart or it's shorted, and the Q1 (2sk2662) which would check to be shorted inside the heat shrinked wrapped board next to the blue relay and the smd zener diode ZD8018 (shorted) along with the ceramic fuse F8001.
I don't remember the value for the zener diode but there's lots of them with the same color code. You will have to take one of the others off to test on a resistor jig to get it's value.
The 2SK2662 is a cross for the original.
