Question about Sony FD Trinitron WEGA KV-34HS420 34" TV

Sony WEGA KV-34HS420

I have Sony WEGA KV-34HS420 TV. I currently have a HD cable box that is connected to the TV. The box is connected to the TV's Video Input 5 via video Y,PB,PR and audio (L/R) jacks/cables. The TV has been working fine for about a year. Recently I turned on the TV and I tried to watch HD TV via Video Input 5 (HD input) and the color looked terrible (ie no red and very dull lacking any bright colors). I went to the video settings and the color could not be changed or enhanced. When I changed to Video Input 1 (basic cable TV HD), the color was fine. I thought there may be a problem with the HD box so I connected another HD box to the TV. I had the same color problem on Video Input 5 with this box also. Does anyone know what the problem may be? Could there be a malfunctioning component used in the high definition circuitry that is causing a problem? If yes, what component could it be and how easy is it to fix? I am dreading bringing the TV to a repair shop because it is very heavy and difficult to move. Any help would be appreciated. Thanks, Jeff

Have you tried a different video cable? If its not a physical issue then it may be a compatibility issue. See if the TV and/or PS3 need a firmware update. Let me know if you have any further questions.

Trinitron tv won't come on. says please wait

There may be a issue with the tuner on the set but there is a way around that.

With a cable box with audio/video out jacks connect to the same kind on the rear of the set---go to that input on the set and should see picture and sound---leave set on that input and change/select channels with the box.

No sound on my DVD. Using S connector or jacks. Swapped DVD player, checked the cable connections, went through the menus on both the player and the TV. Never was a problem before.

if you are connected the S video output of ur dvd to ur tvs s video input , the u should connect another two RCA cable fo audio.S video connection is only for video input. connect the audio out put of ur dvd to the corresponding S video audio input, using a stereo RCA chord.

Is my tv digital?

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).
