I have a Viewsonic N2750W LCD TV. I have been having a problem with my satellite TV. I recently had Direct TV receivers installed on TV’s (1 TV has a HD receiver and the other 2 TV’s are older CRT TV’s with the standard receivers.When I hook up the 3rd standard direct TV receiver to my Viewsonic TV my HD receiver TV signal goes bad as well as the other CRT TV’s pictures. Once I remove the Coax cable from the Viewsonic TV signal coming from the satellite box, all TV’s are fine. I had a Direct TV’s rep come In and have replaced the line as well as splitters and receiver box with no change. They have stated that my Viewsonic TV is the problem. I have disconnected all possible equipment (IE video games PC input A/V and S-video components).My problem still exists.

Based on your description, it is possible that the power supply is starting to go. Before doing anything, first check to see if it is the TV or the source. Use a few different sources to narrow down the problem. You didn't mention what type of hookup you used from the receiver to the TV. Assuming you are using HDMI, it is possible that the cable is intermittent. Try using a different one. Also try as below. 1. Once the TV is working with sound, what happens if you turn the TV off and then back on, is the sound still there? 2. Use the TV antenna input to see if you can replicate the problem using an antenna. If the problem is indeed the TV, it should do the same with the antenna.
Yes there is... You are going to need a VGA cable and an 1/8 audio cable (for sound)

The on your tv you will hook it up to the vga port as well. Page 7 of the following document shows a pictures of the back of your tv. You will hook it up to "L" on the diagram. Be careful to not bend the pins in the connector. http://www.viewsonic.com.au/support/manuals/files/LCd%20TV/N2750w%20User%20Guide%20English.pdf
Switch your tv over to the PC input by clicking the "Input" button. Then make sure your PC is sending a signal, you might have to hit the function key to switch the view.
Hi. can you list the symptoms so the people here can confirm that the main board is the problem? do you have the back off of the tv? is it a VS10576-1M? with a bit more info it may be possible to make less costly repairs .
Firstverify that the direct TV satellite box is set to receive and display digital stations. If you old set on the sat was analog, the box may not have been reset. You may have to contact you satellite provider. Next you will have to go to the TV menu and auto program/scan in the stations. This should pick up all the stations.
I spoke to someone at Best Buy yesterday because I had the same problem. In your TV functions you have a text box on. You have to change this to off or to a closed caption setting. Hope this helps.. :)
