Hi, As far as finding replacement inverter you can do a search via google to see what you find. However, the inverter can be built into the main board of the TV, which would require you to replace that. I found through a quick search that the main board can be had for about $30. http://tvchopshop.com/all-tv-parts/proscan-plded3996a-e-main-board-3393a-zp-vst-3393-a-refurbished/ It could also be a power supply problem too, bad caps, as well as the backlight itself. It looks like you could contact the above site and ask them the typical failures of this TV for the symptoms you are seeing. If you consider yourself experienced with electronics repair, you could repair it yourself. Otherwise consider a new TV or taking it in to a repair shop.
