If I understand your problem correctly it sounds as though when you watch your TV through the tuner you get nothing (no sound or picture) but when you watch it through the Aux inputs (with DVD or VCR) everything is fine. If that is the problem you either have a bad tuner or a bad matrix IC. I've seen both problems in this model and the cost to fix either is about the same. If you know TV safety and can solder unplug unit, remove the back, remove the main circuit board, remove the tuner from the board. This web address http://www.moteva.com/shop/customer/home.php?cat=267 has an original tuner for $18.00 US plus shipping. Install the new tuner and give it a try. If all went well this should solve your problem. If not you will probably need a service manual to locate the matrix IC. http://www.servicemanul.net for $16.00 US as a download. Locate the matrix IC. It should be on a vertical board on the left side. You should be able to get it at this website http://www.tritronicsinc.com This should resolve all your problems. If you can't solder or do not understand electronics you should have a repair tech fix it. Cost should not exceed $100 to $150 US. A free solution would be to hook up a VCR to the Aux input and use the tuner on the VCR and forget about trying to get channels through the TV tuner. It's your choice. Good luck and remember safety.

No sound
There can be any number of reasons for this problem - solve it diagnostically by starting with something that you know is working and work through systematically to the other end.
  1. Test a microphone on a separate amp to make sure it works okay. Check amp and speakers working. Check that all output cables from mixer to amp are working by testing separately.
  2. Plug microphone into a channel on mixer. Also plug in headphones and turn headphone volume control up.
  3. Make sure input sensitivity knob is turned up a bit (say half way) and main output faders (yellow) are up.
  4. Check that channel is turned on (little button just above the channel fader- needs to be pressed down)
  5. press pfl (pre-fade listen) button (next to button to switch channel on)- do you get any sound on main output or headphones or any indicator lights on mixer to show signal is getting that far (eitehr the individual channel metering lights or the main ones in the central section)?
  6. turn off pfl - make sure channel fader (slider) is up - normal position is ) - about 3/4 of way up. Check lights again on individual channel and main output section - any signs?
  7. Is the sub mix button for the channel pressed down - in which case you will need to bring sub mix (red) output faders up as well as main faders.
  8. If you have got signs of signal on the individual channel but not main see if the channel has been routed somewhere odd (like a subgroup of channels).
  9. Plug a working amp and speakers into one of the auxiliary outputs and use the relevant auxiliary send knob (on each channel just above the faders and pfl switches) to pan some signal to that auxiliary out - do you get anything? There is also a headphone socket for listening to the auxiliary channels (with a selector switch /knob to determine which one - make sure it is in the right position) try listening to the auxiliary output with headphones - anything? If yes the problem lies in the main output section.
  10. Check that there is not a jack plug in the insert socket (to route signal through an external effects unit) without a matching return jack being plugged in - if appropriate is relevant effects unit switched on and correctly set up - if unsure remove the insert plug to take it out of the system.
  11. Make sure any mute buttons are not switched in on main outputs.

I have a 42inch lcd polariod tv and the screen comes up blue no picture or sound
It could be the blanking circuit displaying a blue screen if no or a weak signal is connected to the TV. If you have a DVD or VCR try to see if you get picture and sound when ether of those devices are connected to the auxiliary input. If yes your signal input is weak, or you are getting no signal at all. If you go into the TV do you see text? If yes make sure you’re on the correct auxiliary input. If no text is visible the problem is internal and the LCD driver circuit needs to be repaired. If you see text and you are on the correct auxiliary input, but you get no picture and sound then the problem is internal and the front end tuner needs to be repaired. If you see video and hear the sound make sure your channel is correctly selected and set to a working channel. If you have a cable box remove the input to the box and connect it into the coaxial input on the TV and see if you have a picture and sound. If you do the cable box is defective. If you do not see any channels the cable may have lost its signal, and you should connect the cable to another device to check the signal quality. If you have a satellite service provider, and you use a known working device to check the signal and the device works then the TV needs to be serviced.

Cant get game to come on
On the old TVs, to display a video signal the TV must be tuned to Channel 3 or Channel 4. Some TV have the video channel on Channel1.
Connect the console to the TV, tune the TV to Ch 3 and then to CH4 to find out out which is the video (or auxiliary input) channel.

Want to listen to tv channels through home entertainment system
You need to get a 2 to 1 plug, that is, one will be connected to the earphone side of the TV and the other two will be connected to the Auxiliary or Video of your home system.

Check first, before going to buy so that you can get appropriate one.

Best wishes

If you cannot get the original remote or a more compatable aftermarket remote, you might try hooking up a VCR or Cable box to the auxiliary audio/video jacks and use that input while changing channels with the VCR/cableBox.

'No Signal' on Sony XBR
on the tv remote: press menu, external entry is highlight (yellow) right press on the outer circle then scroll down to video 4 (satellite entry) (it could be on video 3 depending of the satellite assignment entry) when video 4 is highlight (yellow) right press on the outer circle on the screen you will see 1080i if settle on an HD channel hope it will fix your Sony Bravia..
