The loud pop was generated by the explosion of one of the capacitors from the power source. Open the back of the tv and replace all capacitors from the power source - if one has failed so badly  then the others can't be far behind. After that check what other components the failed capacitor might have damaged: rectifiers, coils and the IC's from the Y and Z -sus board.
Basic knowledge of electronics is required, if you don't have it then call a certified repairman.

Loud noise then lose picture


The green power LED probably is merely indicating that power is getting to your TV but the internal power supply is failing as evidenced by the loud "pop".

My Westinghouse 36 inch TV has picture and sound when I turn it on but when I change channels, the picture disappears and I have only sound. The picture comes back if you turn the TV off and back on but...


Hello, it sounds like your inverter board is goin out on the set, when you change channels if you notice on almost any TV the screen goes dark and the new channel appears, it sounds like you are not getting enough power out of the inverter board to power up the backlight enough to come on. This is why the sound remains because everything else works fine and the sound is connected to the main board.

LG plasma tv made loud popping noise


The plasma gas tubes may be damaged or the gas couldve leak out. remember plasma have to remain upright at all times even when transporting them, if they are not you should just set it up straight for about 3-4 hours before turning it on.

Olevia LT27HVX 27 just blue screen


I just had this same problem over the weekend. Is your TV hooked up via HDMI?? Mine was and i've been having problems with the tv image shrinking whenever i turn on the tv, so i would have to change the channel 1 or 2 times for the image to come up normally. On Saturday I went to change the channel and then all of a sudden I hearld this loud pop and when the image came on it was just a sky blue screen, I couldnt see anything, but I could hear the channel. So I disconnected the HDMI and hooked up the tv with component cables I had and now it works fine. I ordered a new HDMI cable just to see if it will work again. If not, i'm calling Olevia.

42 inch LG Plasma TV - Lost picture


Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.

TV or Satellite Box Problem?


Do you have a VCR or DVD recorder? If yes, set it to record what you are watching. After a "blackout" rewind the tape and review it. If there is a blackout on the tape, the problem is the sallite box, if not, it is the TV! QED
