i have an RCA 27in. SDTV, i've had it for a little more than a year, last night i went to turn it on, the power light blinks for a while then comes on but the screen does'nt and the remote does'nt work. I unplugged it for a while thinking maybe this would fix the problem, but when i plug it back in it makes a strange beeping noise and it still doesnt work...the tv worked the day before with no problems... wuts wrong and how do i fix it
