Was watching TV, heard a pop and the screeen went black. Now when I turn it on, the pwoer light blinks green but their is no picture or audio. The light then starts blinking red

Is is standby light blinking red or any other light? Let me know how many times red standby light blinking after three seconds long pause to provide you helpful info.
It seems pop sound was due to broken lamp, please check lamp inside tv and if it is broken, replace it to solve tv problem.
Hope this will help.

Picture & sound go on & off every sec, red light blinks 5 times

helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
