My Toshiba tv goes to max volume every couple of minuets by itself

Do you have something new in the room that emitts IR signals?
You need to isolate the TV from a possibly rogue IR signal.
Try turning everything off in the room, unplug everything except the TV and Cable box if you are using one.
Turn off all the lights and turn the TV on and select a channel.
Is everything working, is the volume OK?
If you are still experiencing volume issues then this is TV problem and you will need to see a service centre or repair shop.
But if the sound is OK, then you can now start turning things on one at a time to see which device is causing your issue.
It could even be a light that is flickering at just the right frequency to cause your issue.
If it is a CFC or LED light, try a different manufacturer

Hi. My playstation won't work at all. When i try to turn it on, it goes on sometimes on the tv, or else, it says that i don't have connection from the PS3 to my tv.. I Checked my HDMI, and...

If the screen is just black and the PS3 doesn't turn itself off, then it could just be that the video settings don't go out through the correct output. This will reset the video output:
  • Hold the power button for 5-10 seconds until you hear two beeps; then let go

I have a 50 inch LG plasma tv that is less than 2 years old. It use to turn on by itself throughout the night, and now it's completely not working???

Hi there
Try doing a system reset on the TV, by unplugging everything from it, then wait 3 minutes and plug the power lead in only. If it works, then plug everything back in one by one. If the problem persists it may be that the software has been corrupted in an update process, which can be performed at night via the aerial signal (this may be why it was turning on at night). In which case contact the TV manufacturer.
Hope this helps

Make sure you're running the latest firmware version. 2.76 right now.

If you are and you still have the problem then it's probably an issue with the PS3 itself.

Easiest way to confirm is taking your unit to a friends house and using his tv and his cables.

Hope this helps.

Control buttons don't work!?

Same problem. While waiting for feedback from their support, after trying everything I could think of with no result, in frustration I just shut it down and turned off the power to everything since I couldn't turn the monitor off. Left it overnight and this morning when I rebooted it now works so it must reset itself. Good luck
