so the model is 889gl-80np/c/t

it turned on when i got it. I programed it to power on in last state (588998 then 127210 codes) tried it out and it worked) this is all in house with the A/C plug so far. Now a few days later i plug in power and nothing. As i put the barrel connector in the red power led flashes bright and the blue button lights flashes too. then the red power led dims a little and thats it. none of the buttons do anything. I haven't opened tha case and I am trying to get it replaced, but if that doesn't happen, do any of you have suggestion on what to do?

I read the "everthing you wanted to know about you Lilliput" stickie. I don't think its the internal fuse because the power led lights up. Help or I may have a 8 inch, 1 pound, 250 dollar paper weight.

Thanks,
Jon
