Sony TV snow at startup

1994 model Sony KV20S10 Trinitron Color TV has s**w and ** sound at startup on all channels and after undetermined time will come on with perfect picture and sound quality. If turned off/on the problem again starts. The TV is operated on locl antenna (rabbit ears) and the menu is set to "cable-OFF". One suggestion on this site advised using a straightened out paper clip inserted into cable connection on TV and have TV menu set to Auto Programming to see if any channel would appear, **ne did as there was ** change in the problem. Any suggestions?????

Why does a Sony Trinitron when on Video 3 works fine with dish. When on channel 3, color goes to b & w, then snaps back to color. on a regular cycle ?


your converter box has a channel generator for the channel #3 and you tv has a tuner set to ch#3 that and a coax wire . every part of that system has to be working correctly to send video ,color,sound if even one part of the system is a little off you run in to problems . most likely your problem is with the converter box channel generator . contrast that to when you get the signal from your video input . with that simple system you just take video from the video board in the box and send it directly into the video board in the tv .....a lot less to go wrong .

When I turn the tv on (vega fd trinitron) the scren is all snow. There is no signal.


Hello
Have you tested it with auto tuning progremme process. If it snow there, your TV may be working properly. Sometimes its signal input path is not Ok. Without any signal, all TVs may show either snow, or a plane blue raster if its blue back function is on. You just do the automatic tuning process once again after connecting it with an external or internal antenna. There is a socket provided there in the back side of your TV, and marked as VHF/UHF. Connect the signal source to it first.
And set your TV to autotune by slecting it from the menu of your TV. The TV will search for all the channels available at that time, and after searching is completed, it will stop and show the first channel received. Afterwards you can chage or delete or skip unwanted channels. You may have its manual with you. All the descriptions are there in that manual. Ok.

I did a reset on my Sony WEGA TV but now it's not connect with the cable box. Just says no signal. Screen is all snow and no sound other than static.


you need to reprogram channels. Itll only pick up 3 if you are still using coaxial cable from box, or change input to DVI/HDMI, aux, etc.

Your tuner (in the tv menu) is probably still set on "cable", but it should be set on "off air" or "antenna". When you first turn it on, it looks for a cable signal and when it can't find one, it automatically searches for an "off air" or "antenna" signal. Once it finds a signal, then it stays on and runs ok. If you shut it off, then it has to go thru all this again.
There is a very high probability that this is your problem (about a 99.99% chance). Just go into your menu and select "tuner" or tuning or "input select" or something in that "neighborhood". Different TVs call it different names, so just put in on the option other than "cable". If you ever get cable back again, then, of course, you have to go back into your menu and set the tuner to "cable. Hope this helps.

No picture or sound


If you see only snow and the words "NO SIGNAL" are displayed, and you know that you have the set hooked up to a good signal and the TV is set to the right channel, it means that your tuner has stopped working and needs to be replaced. First, though, make sure your signal is good. A good way to test this is to hook the TV to a good VCR, put in a good pre-recorded tape and hit play. Tune the TV to channel 3 (or 4) and if it is still all snow, have the tuner replaced by a qualified tech.
