That's really half the answer to what i'm looking to do, if someone knows how to dump the firmware without removing the Firmware chip from the board i'm sure he knows how to upload the firmware back without using the USB.

my last resort is removing the chip and program it then solder it back , the only thing making me wait for another solution is that i need a TSOP56 adapter for my chip Programmer to be able to program the s29GL128 flash ,and to build the adapter its really a time consuming thing.

Hopefully someone will step in with a solution .

by the way the symptoms of the corrupted firmware is that the TV will turn on then show the Big W Logo and then turns back off with an orange Light , it will never turn to Blue light i'm sure many of the posters to this thread have this problem on there TX-47 or TX-42 and they end up throwing the board away.

Hi! I'm EXTREMELY new to this. After a power outage, my TX-47 won't turn on and only shows the amber light. I wanted to replace the bad cap, but I CAN'T figure out how to access it. I unscrewed all the screws that I could find but I still can't get how to open this enclosure to get to the board.

Can anyone help? Thanks!

If yours is the same design as mine then its simply a matter of disconnecting the cables that attach to the main board and sliding the board out.

Viewing the rear of the tv the HDMI ports should be on your left and the component connections should be on your right . Remove all the screws from the side with component connections and remove the flat headed flush screws from the HDMI side. You should be able to then pull the board out from the left side (HDMI side). When you go to install the board be careful, the board is supposed to be inserted between these metal slides.

If you cant figure it out I can get some pictures.

Thanks for the reply!

I disconnected all the cables and took out all the screws but I still can't seem to slide the board out. Did you have screws inside that (I think) held your board in place like in my picture?

My pictures show the bottom view and the top view. They're the screws in the corner that my screwdriver can't get to

No I didnt have to remove any screws from the top of the board. Those screws help hold the metal plate that go around the component connections. See http://imgur.com/a/rNfSQ#0 and you can see how the board is supposed to slide out via the HDMI side.

I see what you mean. I'm sure I got all the screws I need to, and I'm pulling on the metal plate quite hard to the point of bending it, but it's not budging.

I think the metal slides are holding my board in place really well. I'll just keep trying though.

Thanks for the help
