I am still trying to find EEPROM. My TV (lnt4671fx/xaa) has several chips look like that so very confusion. What should be written on top of this chip? So I don't short the wrong chip.
Thanks for your help!

I had this issue on a friends TV that he picked up from the local tip for £25, I confidently told him to bring it over and I'd fix it.
I opened the TV up and the usual suspect caps had been changed, so I moved onto the eeprom reset, it took 20-25 attempts and then fired up.
I went through all the options without issue, but when I selected movie mode the image went a vivid green, like how I would imagine and acid trip would be - I tried the factory defaults - still the same.
I went into service mode and checked the config for the panel itself, there seemed to be lots of options, I noticed one of them was set to 26" - I changed this to the only 40" panel option, saved and restarted the TV - all working great now.
To the guy asking about the eeprom location: The eeprom is on the underside of the board (when viewed with the board bolted in) and it is in the lower corner on the outer side of the board

Hi
Sorry to bring up this thread again, but I'm having the same problem. I've replaced the capacitors but it still won't turn on. I was wondering if someone could explain to me what is "shorting" . I've read both threads very carefully but I don't know what you mean by shorting the two pins. Also, you talk about removing the "short" after turning the power on - is this dangerous? (don't want to get electrocuted)
thanks for your help

Shorting is basically joining two points of a circuit together with a conductor (wire, solder etc). In this case its the two pins on the eeprom and the best way I found to do it in this case is by soldering a length of wire between the pins. This is quite tricky if you are not used to soldering. To remove the short you just cut the wire i.e. break the connection and this is at low voltage so won't be dangerous. However there will be much higher voltages present on the PSU and inverters whilst you have the back off the tv and are completing this procedure so be careful.
