HELP! what did i do? black blank screen after update

[artapart69]

ok, heres what i did. trying to get an eclair rom to work n this pos tablet made my screen go black, or i guess to correctly put it go dark. the only way to see the icons on the screen is 2 b n low light and to shine a flashlite directly at it. what i can make out when i do this shows me a working tab, minus a screen.

ive tried flasjing other roms since and only get the same thing.

what did i do to this piece of shi*?????
help me...
