The input selectors (Video 1,2,3 and Channel) they shake a little up and down. no matter on what input i make my connections i don't get any sound or image, if i select the channel input i cant change channels it just stays on 0 and 0000 underneath it.

Hi,
Either that of your tuner block is acting up. Most Sonys of this production year uses a tuner block that requires 33VDC tuning supply. It has been known for this zener to fail or the capacitor parallel to it. At times, it could just be the tuner block itself.
Should you venture a DIY, it would be to your advantage to have access to a service manual or at the very least a schematic diagram with voltage readings.. It further requires familiarity with electronic components and circuitry, use of a DVM and a soldering iron. Should you be uncomfortable going this route, then perhaps your best bet would be to seek the services of a qualified professional
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
SOURCE: 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.
