TV won't "talk" with satellite cable

Try to see if you have 5volts for your EEPROM. If the voltage is normal try to replace your EEPROM or try to reprogram it. Your EEPROM is corrupted so that's why it will not store data.

Input problem

If you have the original remote, hit video, source, or input button, if it dont have them, then try to change the tv to channel 00 (zero or zerozero), if not then the channels might have to scroll to it, from channel 02 down to make it loop, if it goes to the next highest channel, then you need a remote. It may be set in the menu options to have the video source not saved to your list of saved channels. when you scan the channels, the tv might not look for the A/V source (audio / video), maybe just the RF source. The 3 DVD RCA wires are 1 video and 2 stereo, one stereo for left and one stereo for right. The TV has only 2 , 1 for video and 1 for mono 1 channel sound. This wouldnt have anything to do with why you cant use the DVD player. but try that with the original remote (or a universal remote that is set to your tv set that has either video, input, source or something similar. It is what tells the tv to change from the cable source (RF) and the AV source (the Red White and Yellow plugs, in your TV's case, 2 plugs, one yellow and the other either red or white or something). Dont really know how to explain it much more but hope it helps.

No Signal through on my main TV input.

This may be the tuner or IF module that is failing. It may also be a voltage supply fault to these modules. It is impossible to accurately speculate without actualy troubleshooting the set.
