my sony is crazy...please help

my tv model # is kdf-55xs955 I turn the power on and the green standby flashes 5 times tv  turns on. after about 1.5 minutes video and audio lost and green standby flashes 30 times and gradually "flickers" on by the 37 blink video and audio is on. this vision does not stay long enough to keep my kids from yelling and screaming that our tv is still broken... this blinking dance just continues to cycle.i have tried to give the tv a break and force myself to keep it off. i then tried again now the  blink is red and goes 5  times and no video or audio.then i have to wait again to turn back on  (my tv hopes still shattered) the viscious cycle goes on....  3 years ago i spent my tax refund on the purchase of this tv cause i was convinced into believing that they dont break the worst that would happen is i would need a replacement bulb... well here i sit with a big blank tv and my two little ones trieing to do family guy skits to keep me sane(its not working) please help
