so i ordered a new main board from tvserviceparts.com. a few days after i placed my order, i received an e-mail saying it was on backorder for 2 weeks, and it would be in november 17th.
november 18th i receive an e-mail that the part is still backordered, and the expected arrival date was unknown.
so i canceled my order, and found a main board on eBay for $110 shipped.
just received the main board today, swapped it out in about a half an hour. turned on my tv, the blue ring lit up, but no picture, and just a blinking green led in the bottom right hand corner. this was as expected, as i know i needed to get into the service menu and copy the dmd data over. so i had to unplug it to turn it off, plugged it back in, and pressed mute 1 8 2 power, and it didn't really do anything. then i tried hitting mute -> 1 -> 8 -> 2 power (thinking maybe the arrows were actual right buttons) and it got me into the service menu! i did the DMD -> DIGITAL option, turned the tv off, turned it back on, and we were in business! hooked up my ps3 to hdmi 1, and it was working!!! hell yeah. checked hdmi 2 and hdmi 3, they worked as well.
SO, i turned it off, unplugged it, flipped it back around on the stand, so i could put the bezel back on as well as the entire back cover. Screwed everything in, flipped it back around. plugged the ps3 into my hdmi receiver, plugged the hdmi receiver into the hdmi 1 input, turned the tv on, and then it started doing the same thing it was doing before i did the DMD -> DIGITAL thing. no picture, flashing green LED light in the bottom right corner, and unable to turn it back off without unplugging the power cable. so i figure, ok, maybe i need to redo the DMD -> Digital step, but i can't, for the life of me, get back into the service manual. i've tried a couple dozen times, and i'm trying not to get frustrated here. i don't have anything else plugged into the tv right now, just the power cable, and i can not get into that menu.
are there any tips on getting back into the service menu? anyone have any thoughts or advice?
