Stereo works fine, all buttons work fine, and buttons light up. However, the LCD screen is now blank.. which would lead me to believe it would be the ribbon cable.. but there isn't one. Detachable faceplate.. tried cleaning contacts, no luck. Please help.
I dont have a solution for the problem, but my Kenwood is doing the same exact thing. My fluroscent, if it is fluroscent, is not cracked. The display come on and works fine every so often. If it were cracked, it would not do that. Any other suggestions?

Is the lcd screen completely blank? Or does is it just the touch functionality that is not working?
If the screen is blank, though the copier still turns on and appears to function (test it by printing to it,) then you most likely have a failed power inverter board. This board provides the current needed to operate the lcd screen and is a rather common failure. However, if it is just the touch feature that is not working though the screen lights up, then you most likely have a ripped ribbon cable that connects the lcd touch function to the main board on the lcd screen.
White screen means that your lamp (back light) is working absolutely fine, but you could have a loose connection for the data ribbon cable, which sends the images to the monitor.
Carefully open laptop to reach its lcd, there must be ribbon cable which looks like this:
It is very sensitive so be very careful with that, very gently remove this from the chip and reconnect it.
Hope this helps,
Please feel free to ask me any further.
I had the same problem and when I took the remote apart the ribbon connecting the lcd screen to the remote controller board was sheared. The remote was dropped and the impact caused two of the traces on the ribbon to tear.
You can open the camera and check to see if the LCD ribbon cable is still connected to the main board. If it was dropped they can become dislodged. There are two cables the smaller one is the most sensitive to coming loose. When disconnecting and reconnecting the ribbon cables, make sure you are careful while lifting the tabs that hold the ribbon cables in place they are hinged and will lift up and the ribbon cable will slide out. Note the large ribbon cable feeds through the camera to the front main board. Hope this helps
If you get a blank LCD, dimly lightened by a whitish back light, then the LCD display eis either faulty, badly connected, or the ribbon connector to LCD is defective. The camera must be taken apart, ribbon cable tested, and eventually replaced and adjusted. If all contacts on ribbon cable return continuity (cable is fine), then LCD is faulty, and must be replaced. Althought the job is not too difficult, an user without experience may damage the camera in attempting this repair. My first suggestion is always taking the unit to a camera shop.
