No signal or sound but menu comes up

I have a Sony KP-57WS500 I have an issue with. When I turn the TV on it comes up with "No Signal" at the bottom of the screen. I've tried every video input on the back of the TV and nothing happens. The menu still comes up and looks and operates just fine. I checked and there are no codes stored in the TV. I've heard this could be caused by a bad "signal" board but I'm not sure what board this is referring to. Any help would be highly appreciated. Thanks!

Sony kp-57ws500 flashes blue, green, red then turns off

Re-insering the flyback wire is usually very easy. Push in and give a slght turn and check to see if grabbed. It sounds as if there is more issues than flyback wire. TV should turn on without one crt connected

Tv comes on for a few minutes then goes off

If you take off the front bottom panel of the tv wich is easy. Then you will see 6 tuning knobs at the bottom middle of the tv .the top 6 control contrast for the lights dont mess with those. the bottom 3 are the power to each light.red is bottom left if your screen went blue it makes sense that the red is starting to go but if you turn down the power to it left 1/8 turn it should fix it for awhile .Its easy.

Sony KP-57HW40 tv is what we have now and is this a high definition tv?

After the FEB 2009 cut over, your "OLD" tv will nolonger be able to receive OFF THE AIR signals as they will be broadcast over different frequencies. HOWEVER, as long as you subscribe to CABLE or SAT TV (Dish/Directv/etc) your old TVs will continue to work as they always have -- (because the signal is not OFF AIR) but you just won't have an HD picture.
