Hi,
I replaced the main board on my sony 55w802A with a 47w802A. The TV comes on and even flashed SONY across the screen once while trying to reset it to factory setting. However, it usually comes up and does one white flash followed by about 1/2 second intervals of green/amber. I think I need to replace its firmware. I have the firmware on a USB device and have put in in the USB port. However, I can't seem to get further then this following instructions on how to update firmware. If tried unplug 1 min and plug back in and hold up arrow and press power on. This does nothing. No text on screen. I have other replacement parts from a 47 inch model and am willing to replace these too. But it really seems like all i need is a s/w update. I assume all the s/w is the firmware. I'm I correct?
Any advice welcome?
