    It will turn on fine. Picture is fine, after awhile it just goes black and begins blinking the power light on and off. The picture, when you turn it on nomrally makes kind of a frequency sound, well when its blinking on and off, it makes that sound as well. Its a high pitch switching frequency sound. I simply hit it on the top and it turns back on for awhile. Had the convergence replaced already, its not the issue.

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

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.

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.

Hitachi 43fdx20b too much red, green is off

If your Hitachi TV was manufactured 15 years ago, it most likely is worn out by now.

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
