Luckily it apparently is also possible to ZOOM-IN on the example picture on the left in the RT809H programmer window on how to place any chosen IC. In case of the mentioned Winbond 25X80 eeprom it shows pin 1 in the up to the left direction and pin 8 up to the right in the lowest position of the socket. (Furtest from the sockethandle on the upper left),

I have a 55 Inch 3D Toshiba that has the same problem and I can get the firmware. I have a programmer but I need the firmware. The model of the TV is 55TL515U. Does anyone have this firmware that I can get or know where I can get it. Thank for the interesting article.

The RT809H is a great programmer for that, in both reading and re-writing/flashing of firmware. Although it is autoverifying and very fast I noticed that if we place Bios chips turned 180 degrees wrong in the RT809H socket, chips are still recognized and read but is followed by a screenmessage saying that there is a verify error at address 000000. (sadly the screen example of the programmer software program how to place in the chip is very tiny and almost impossible to see, so that mistake is easily made).
Today my programmer luckily fixed another firmware problem with a dead Asus P5KPL-AM SE motherboard that showed no video output and was useless until I re-programmed the sop8 25X80AV Winbond Bios chip with Bios version 0702. A diagnostic card inserted in the mainboard PCI slot showed a running clk signal and a post end code of 32. Which turned out being caused by a corrupt Bios chip. Which easily happens when the Asus mainboard apparently flashes unexpectedly its own firmware (every Asus mainboard is included with an EZflash utility and the EZflash program that is able to fix dead mainboards causing more problems instead of solving them) while a windows installation was started from a iso image on USB memory stick.
