Display Problem I have problem with display I.C that makes only light to show on

I think you need to replace the display of your tredmill. Everything is fine with your tredmill but only it`s display need to be replaced.

While on-hook or receiving a call, The Navigator Key is used to adjust the display contrast*.

It could be a bad video cable or a failed screen. You could try reseating the cable at both ends. You might try moving the screen forward and back to see if the screen flickers at all. That would confirm the cable. If the backlight went out on the screen itself, you should still be able to see the image under bright light on the screen. It just would not be back lighted. If the screen is bad, take it out, look at the make and model of the actual screen (a Dell laptop could have a Samsung screen, etc) and then look that up specifically on eBay or Amazon for the best price.

Yes, I have exactly the same problem after running the de-scale routine, we've only been using the machine for 4 months (in Melbourne where the water is soft). You can dimly make out the icons on the display and the machine works Ok. The display contrast is set correctly, yet the green images are not showing up properly while the red images do show up.

Showing blank(white screen) display a even it works. There is problem with your display IC chip which has been damaged you need to change it and get you software update.There is conection loose i this.

My N72 (Nokia) phone’s display shows blank when switched-ON. Blank in the sense means that the display lights are ON, but no images in the display. Sometime the dispay comes and goes. In addition, the phone is not ringing or can’t make calls. Can anybody help me?

my Samsung A800 also lost its inner display recently. When I open the phone, the inner display lights up but fails to show any image. Outer display is mostly OK, once it had trouble to "lock" the image and after opening and closing the phone a few times the outer display showed the image with light and dark bits inverted.
Switching phone off and on restores the inner display most of the time, but the image only lasts until I close the phone.

make sure that the additional box is hooked up to the cable, or else the display will not function
