I am a technician for Comcast and recently a customer gave me a Hitachi 53UWX10B 53" 16:9 HDTV Rear Projection Color TV because it had a reen line bowing at the top sagging down. I took the TV and tried to fix the green geometry in the service menu but i obviously did something wrong because now when i press the power button the red light on the front just flashes and i dont get any picture what so ever. I am thinking i overdrove something some how and this is its way of letting me know. I was wondering if there is any way I can restore the tv to factory defaults from the circuit board. Any help would be greatly appreciated and I am pretty much willing to try anything no matter how complex.
