Re: RCA Model # LED52B45RQ not turning on

OK.I bought a new eeprom for the main board. Television turns on now but the screen is upside down. I made sure that the number one pin was at the arrow on the board. Anyone know how to fix this??

I read about another similar problem on here but it was slightly different in the voltage readings. On the main capacitor I have 167 dc with it off (red light on) and 396 with it turned on. Voltages on con2 are all showing what they should be according to the markings next to it when its on. There's no bad caps showing. Tried unplugging the con5&6 connectors one at a time to see if there is a...
