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.

If you have backlights its not going to be the tcon for future reference. you have some shorted or open LEDs in the panel. Check the voltage going to the LED sets, should be 100 plus volts

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions

Samsung LN46C630K1F No Backlight, Replaced Board, Still Doesn't Work


because you see a picture with a flashlight it means your power supply is fine. you probably need to replace the backlight inverter board if you haven't done so yet.if that doesn't fix it then you have a bad panel, and at that point it will be too expensive to replace. Good luck!

Picture went out on p50hdm Vizio Plazma tv after loud POP


It's either the backlight lamp or backlight inverter is busted due to a power failure or fluctuation. Here's how to determine which is which:
  1. Grab a flashlight.
  2. Turn on the TV.
  3. Shine the flashlight onto the screen.
  4. If you cannot see any display even a faint one, the backlight inverter is dead, else the backlight lamps are busted.
  5. Replace which ever is the culprit.

My acer laptop screen is dark


Hello,

If your laptop screen is dark, it could be the backlight,inverter, or bad lcd. You can test the backlight by starting the laptop and give it a few seconds to load and take the laptop in a dark room and shine a flashlight on the lcd and see if you can see any pictures or icons. If you can, you may just need an inverter to correct the issue, If not, you may need to replace the inverter and lcd both.

If you find that you need parts to correct the issue. I would suggest that you begin with replacing the inverter first, as they are usually less expensive.

If you can supply me with the model number of the specific laptop you are having trouble with and I can try to locate more information on replacing the parts.

Thanks
