Here is my problem. I have the TSU2000 remote. My backlight does not work anymore. If I push the side backlight button nothing. I have to touch the screen to get the remote to wake up but still no back light. My questions is do I need to replace the LCD screen to get the backlight working again? I have read on a couple of threads about replacing the L1 inductor but I don’t have a source to acquire a new one and the replcing of the screen seems the easiest solution if it works. Can someone please answers this question for me? Thanks
