My red-eared sliders refuse to eat anything, even crickets! Help?

[wendy]

My RES turtles have refused to eat for about three weeks now. They went into a little brumation because their tank got so cold and slept for 3 days straight. But even before then, they stopped eating their regular pellets and only ate their vegetables once or twice. After those 3 days of brumation, I woke them up because they're not supposed to be "hibernating" as pets; now, I keep them under a lamp and they're much warmer. However, they STILL refuse to eat! I bought 5 small crickets today, their favorite food, but wouldn't touch them. They acknowledged their presence but displayed zero interest. Is this normal? Will they start eating again once winter ends? Will they die? if they don't eat for more than a month??

Thanks, any advice and help is appreciated!
I've had two RES turtles ever since August 2009. Last winter, they were completely fine. They live in a tank; I do not have any fancy turtle equipment (heater, etc.) since it hasn't been necessary. I do keep a lamp on.
