Why is there sound but no picture?

According to the owner's manual page 2.7 (and this is an OLD [by HDTV standards] set), the TV can only handle input resolutions of 480p or 1080i on the composite inputs. Most HDTV programming today is 720p with some 1080i and 1080p on certain channels (like some Discovery shows about nature). It is possible that your set will not process the 720p signals being sent.

Why does my Sony 57" Hi-Scan 1080i? 16:9 Projection Television keep turning itself off. I turn it on and after 10 min it shuts itself off I can turn it back on but the longer it is on the quicker it shuts...

Sounds like a heat problem. Check to make sure that if it has a internal fan that it is working, and clean any dust build up, most projection tv's have fans, usually the number of flashes indicate a code that repeats.

    TV turns off by itself

    Thus the line connected to a surge protector or some kind of line protector. This can be consider.

    Or if this is a crt type tv. This could be a fault on high voltage section. Horizontal output transistor or flyback. But check also for loose connection/solder crack. That clicking sound may be the relay in action.

    hope i give some correct input.

    What do I need to get for viewing HDTV

    The TV you have will only process an HD via the component video connections. Your cable box needs to have component outputs and you will need to buy a component video cable to connect from the cable box component video outputs to the TV's component video inputs (should be 2 sets, #1 for up to 720p and #2 for up to 1080i...

    learn lip reading..... but really 1080i inputs have to cut main circuit and be processed through your main amplifier .
    shorted or too low a signal at input is a start.

    HDTV Cable box conflict

    This set does not support 480I in the DTV mode, only 480P and 1080I is supported. Try setting the analog setting in the cable box to 480p and that should take care of watching the set in DTV. Most cable boxes have a setting for format changes in the customer menu, depending on the type of box. If you are able to change the format, then the other inputs will not work since they need a 480I signal, as well as VCRs. Another setup could be to use the S-Video cable or Video input jacks to get a better picture in 480I instead of using the cable input. However, when changing from HD to Analog, you will have to change to the correct input on the set as well. Hope this helps.
