You may care to use another HDMI port to see if it works at all. Change the cords around. If you like using one HDMI source, get an HDMI Switch box from MonoJet.com. For about 10 bucks, the switch box solves a lot of problems.

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.

Are these vertical or horizontal lines?

Its not a button, you need to do a factory reset, your manual that came with the TV will tell you how to do it, its different with every make of set

Could you explain what you mean by changes colour, please?
