The tv works fine, can hear all channels except the video channel on the tv - no sound at all - the video when playing a tape no sound either - please help - thanks


Since the sound works on all other channels, there are 2 possibilities:
1) The audio switching chip has failed.
2) The source is not sending the audio to the set.

The higher probability is option 2. Can you please post the make and model of hte set as well as that of the tape player? That info will help to give you more details.
Thanks,
Dan

How to connect surround sound system, at the moment its connected through cable, each time we use the dvd player we have take them out of the cable box then into the dvd player, we have a LG 42PC55 tv.


In order of picture and sound quality -- from best to worst:

1. The best way to connect, assuming your TV and A/V Receiver and/or Cable Box have the jacks, is to use a HDMI cable ( this cable is for both sound and video).

2. Use Component Video out to input (3 RCA plugs, Red, Blue & Green) along with RCA Audio out to input (2 RCA plugs for stereo - 1 for mono).

3. Use S-Video out to input (1 din plug) along with RCA Audio out to input (2 RCA plugs for stereo - 1 for mono).

4. Use Video out to input (1 RCA plug, yellow) along with RCA Audio out to input (2 RCA plugs for stereo - 1 for mono).

Be sure to select the correct inputs on your TV and Audio/Video receiver when you are watching TV. For example if you have connected your TV to HDMI 1 and DVD to HDMI 2, you will not see or hear anything if you don't select the correct input on your TV and A/V receiver for the input you want to see and hear.

Detailed connection instructions will be found in your owners' manuals.

Hope this helped you. :)

since you changed the lamp my next thought is that the color wheel has failed,,,most good road techs can replace it in the home..the cost would be between 220.00 and 350,00 depending on the company...

Sound but no picture


This could be a problem in the vertical sweep circuit, as when the vertical circuit fails, The video or screen will blank out so the picture tubes do not get damaged. In this chassis, I have seen the convergence IC's cause this, or the capacitor in the sweep power supply that feeds the voltage to the vertical IC has failed and blew out the vertical output IC. If you have no solid state repair experience, play it safe and call in a trained tech to assist you in this repair. Good Luck.
