Sound but no picture


Hello!
Does sound comes out of TV speakers? Or you have "home theater" hooked up to?
In first occasion: TV turns on, stays on, display blinks once, then nothing?
Inverter is at fault. Second occasion: TV turns on, stays on, display glows dark, sound OK, no picture: T-con board at fault. Third occasion: TV turns on, shuts off, sound is coming through "home theater"-OK. Power supply or inverter, or T-con are at fault. TV need major diagnostics and repair in every case. Let me know if you can handle that. Will guide you through the process.
Thanks,
Alex.

Turns on But No Picture and No Sound


sounds like it could be a cabling issue, try replacing the cabling (if you have another tv, you can borrow the cabling before purchasing new set of cabling)

How to change from tv to dvd mode


the difference between tv and av, is that av has no showers on the screen. if you change to av you will notice a blue screen, connect your yellow on vedio output and white/ red on audio out of tv
note- before connecting to a vedio touch a tip of your vedio cable some lines will show on your screen, if touch your audio tip harming noise will sound on your tv. if this two happens then you know that your cables are okey. hold your channel button on your tv, channel will start runing after all rf channels finish, tv will go to av.
