Panasonic TX-P46GT30B won't turn on, need help to diagnose what the problem might be. Can't Post

I have a Panasonic TX-46GT30B Viera plasma TV. A few weeks ago it would turn on for about 30 seconds then turn off. It won't even turn on now, no power, no power light indicator, nothing. I think it is the power board however I am just after some advice from someone who will most deffinately have more knowledge about this than what I do.

Thanks for your help before.

Just wondering if you can help with another problem. I ended up having to replace the SC 1 board but when I turned on the TV I can't get any TV stations and there is no sound?

No sound is produced:
• Is Sound Mute active?  (p. 9)
• Is the volume set to the minimum?
• Is Speaker Selection (VIERA Link) set to [TV]?
• Please also refer to “Neither image nor sound is produced” (p. 114)

Hi thanks for all your help.

. sound Mute is not active.

. I have turn the volume up to full but still no sound.

. Couldn't find speaker selection to see if VIERA Link was set to TV.

I've followed your instructions and all that appears is a sub menue on the right hand side saying VIERA Link Control then to the left side of that it says Player.

I've clicked on the player option but nothing happens.

Could the sound issue here be something to do with the type of arial i am using?

It's just that the TV was given to me with no cables and I have noticed that in the accessaries there is an RFadaptor, would this make any difference?

If you have stable video, you should be able to get audio.

I'd start by downloading and skimming through the owners manual, paying close attention to audio/speaker settings.
