Insignia LCD 26 inch

It sounds like yoru PS3 has stopped handshaking with your tv. It can happen. It's possible your brother disrupted the connection by unplugging the PS3 before it was shut down. You can try turning on the PS3 first, and then turning on the tv, or vice versa. If that doesn't work, you may need to invest in a cheap HDMI splitter, to plug the PS3 into, and then send the signal from the splitter to the TV. It has happened to me with a computer with the same hardware, once with an LED tv, and once with my surround sound receiver, completely out of the blue. You can try switching HDMI cables, sources, doing putting the tv into maintenance mode and resetting the software. If none of that works, your only option may be to use an HDMI splitter. I did extensive research and read numerous reviews before I settled on this model, due to many recommendations:

Just in case your HDMI cable was damaged when your brother unplugged it, go ahead and get yourself a decent HDMI cable. The Amazon HDMI cables work just fine.

First off what type of input are you using going from the ps3 to the tv. If your using HDMI try changing the different video settings. Black ops actually has a lot of problems right now on ps3. So I wouldn't use that as the basis of what is working or not, I would try other games to see if it's working. Adjust the video settings on the ps3 and see if that helps. If that doesn't try using component cables and see what that does for you.
Thank you,

The problem might be your speakers. Try a different set of speakers to where your TV system. Maybe the speakers inside the TV is bad.

Silly question -- but are you sure your Sony TV is on the correct HDMI channel? My 32 inch LCD has HDMI1, HDMI2, HDMI3. You must make sure you plug the PS3 into the correct HDMI channel and make sure you're tuned into the same one.

That's because explosions are pretty much only low frequencies, otherwise known as bass. Your tv crackles because the low frequency emitters of your tv are either of low quality or malfunctioning. If you lower the volume of your tv it should fix the problem.

Are you sure the tv is 1080p capable? Usually when "mode is not supported" is displayed, it means that the tv can not handle the signal format that is being input to it. If you are using HDMI, then signal formatting is usually handled automatically. If you are using component video, you will probably have to tell the PS3 to step down the signal to either 1080i or 720p.

Check to make sure it is on either the AV 1 or AV 2 channel

they said there would be a problem for LG tv's try going to your settings audio settings and change stuff around

Go to audio options, and manually DE-select Digital 5.1. That should fix it. It did for me.
