Is it possible you have the "Video input sensor" on. It's in the menu system somewhere and turns the tv on if it senses something connected to it is turned on. Sometimes it gets confused and works opposite what it is supposed to

My hitachi 43fdx20b has a pink tint to it. I have noticed that if i move the tint slider one way or the other it will turn the screen green, but now it doesn't. Does this have something to do with my...

My 43fdx20b had a pink tint to it also. The picture was clear otherwise. I found, on mine, I needed to adjust the Red Screen control. It was located behind the front panel. I removed the two screws on either side of the front panel and was able to remove the panel. Then I adjusted the Red Screen control. I found that if I tuned in an old Black and white movie I could adjust the color fairly accurately. Good Luck.

Red light on front, no audio,video, have unpluged and left unplugged for days , plug it back in and get the same thing

the red light is on because part of the power supply is still alive(usually +5v source), but there could be a problem after the ps that might be causing the tv to go into shut down. that might be why there is nothing happening when power is pressed.

Hitachi 43FDX20B, watching tv, screen went blank, no picture, no sound turn off then back on power light on but the same nothing

The TV computer may have detected an error. See if the problem persist after unplugging the device overnight to reset it. If it does not, the issue may be with the board or its power supply circuit. Probably loose soldering or leaking capacitors.

if you can hit it and it does something it's telling me you have a loose connection. or cold solder joint.
