LCD TV picture screen very dark

Our LCD TV which has been stored in original pkg, used less than 10 times and only 6 mos. old is out of 90 day warranty. We called Memorex Cus Svc and there is no replacement part for the problem.

The screen is very dark, although you can see slight blue image if you tip screen just right. I have opened the tv and can see that there is no bulb or background light to replace. Hate to scrap, TV cost $220.00. Although, dont want to spend 100.00 plus to repair. Any recommendations? Please help
