Usually that popping sound is a capacitor blowing up. There are 2 ways to fix this. 1) replace the cap by itself or 2) replace the whole board with the bad cap. If you are handy with electronics and a soldering iron, replacing a cap is pretty cheap. The hard part is finding one. The local Shack may have one but probably not. If you are not comfortable taking the TV apart, then you need to find a tech to service your TV. Most techs are going to replace the whole board.

TV will not power on.


I guess your TV is DLP.
Please notice the follow symthoms:
When you on TV, did you hear some strange noise from the back of the TV. If yes, the color wheel needs replacing.
If no, check the lamp. Take a look to bottom of lamp, you will see white pot or sometime a pop up there due to lamp cycle is going to end. When changing lamp, check the ballast and power sup, too. If you see caps are poping up. Pull out those board and replace the poped caps.

If you have no video and its making a popping noise its mostlikely shorted convergence circuits. Contact www.TvRepairKits.com and ask them to make you a kit for chirping sets.

50"lg plasma tv


The popping noise you heard it's probably a capacitor blowing up in the power supply circuitry. If the TV is less than one year old, still covered under manufacturers warranty.
Let me know if you need any more assistant let me know.
