Re: 20" sony trinitron KV-20fs100 no signal
It is very possible that the tuner and IF modules have failed. On more rare occasions, the supply voltage to these modules may be missing because of failed components in the regulator circuit that feeds the front end area.
Some other areas of failure can be the uPC controler may not be addressing the front end functions, or the input switching control is not working properly.
The mentioned problems would require an experienced TV tech who has the service manuals, and the tools and facilities to troubleshoot and service your set.
If you decide to have the set serviced ask for an estimate. It may be expensive to fix.

Just reset the TV to its factory settings and check. To do this you have to enter its service mode option. How to enter the service mode option is described in one among the posts at the site linked here.
But, before doing this reset, just connect the HDMI cable to the TV, and input an HDMI signal to it. If there is no input signal, the set will display as 'no input'. Check this first. If you wish to get further assistance from me, come over by FiXya comment.

It is not a matter if your TV is compatible with a digital signal, it is the signal being offered to the TV. Meaning, if you are using Cable TV, you are fine and need no further action because the digital signals are already converted by the Cable Box into either an analog TV (RF) signal, or a PBR (RGB or Comp.Video) signal which the TV understands via a separate input (external video input).
If you have confirmed that there is cable signal but the Sony TV does not sense it, then perhaps the problem is internal to the TV. Primary suspect would be the tuner block/assy and/or its B+ supply. Often there would be two (2) voltages required; 12VDC & a 33VDC (varying). In some instances it could just be the zener diode.
The above of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then 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.
If none of the r.f. inputs are working and you do not get local channels off of a pair of rabbit ears. You may have a bad tuner. Which you can get replaced for 125.00-150.00 or you could run the cable into a vcr input and use audio/video cables to connect to a video input on the tv and switch tv to that input and run the channels using your vcr. In other words, use your tv as a monitor and use the vcr tuner to pickup basic cable. Hope that takes care of it, Russmann.
Did you correctly select the S-Video input on the TV via the remote? In other words, if the TV is not set to look at the S-Video input then nothing will happen. You have either an "input", "source" or tv/vcr button that will allow you to select what input the tv will look at for a signal. Make sure it's set to S-Video.
There's a possibility that you may be experiencing problems with the audio output IC -IC404 - All serial numbers produced until July 2003 might use one of these defective IC's. So if your set was manufactured before this date, that is probably the culprit. If not, and you have it connected to a cable box that has its own volume control, it could be that its volume is turned down and by turning up the TV's volume too high that you are getting this distortion. Hope that helps.
