I need a manual for this TV preferable with pictures showing how to do hook ups thank you

Element TV manuals Go here to get your manual.

What sort of tv do you have?

The camera has to be on th right setting also...is there a manual switch on the camera it self? If not is the power hooked up properly, is there a light switch turned off that actually turns the power off to the outlet your using for the camera?

The wires are not connected to the tv stuid

Most of these TVs show a blank screen unless they are receiving a sinal?

the video format from your medium doesn't support the tv's max resolution

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.

it really depends on the connections you have on you pc and on your tv some pcs have a s video hook up or usb port that can be hooked up to the tv but if the only hook up you have is the cord you use to hook your pc up to the computer monitor chances are you will have to have an adaptor. We run ours thru our playstation 3 because there are more ways to hook things up. You could hook it up to a playstaion with just the cord you already have and run it to the tv I believe that xboxs also have the same attachment. Hopefully this helped somewhat. Its hard to answer because there are several different combinations of attachments and hookups depending on name brands ETC.

You system is still out-putting through the HDMI cable. Press & hold the "on" button after the system is already on, it should go back to regular factory settings & show up on your screen.

you have a bad tuner you can replace it or use vcr if you still have one around. hook it up with av cable like your ps2 and hook your cable to it and use it to change channels. If you want to replace the tuner it will require soldering and you will have to order it somewhere. i would try partsore.com. The tuner is the metal can the cable goes into inside the tv.
