Re: UN46C7000 LED bricked with service menu (changed the mod

My bet is on chip number "10" (4256BRP == ST M24256, 256Kbit I2C EEPROM). It has the right size (32KB), and it seems to be connected to the main SoC - or maybe not, picture quality is not good enough to be 100% sure. What are the labels on the four test pads nearby? Chip numbered "8&...

Re: UN46C7000 LED bricked with service menu (changed the mod

I confirm my previous post : chip #8 should be the one :) To be more confident, you can try to follow sda/scl (the 2 signals connected to via-holes close to the chip) : they should go to the SoC What's the crack on your SoC heatsink ? Hi Oga83, thank you I'll do that. the first photos (the one with...

Re: UN46C7000 LED bricked with service menu (changed the mod

ATMLH006 (number 8) is the best candidate to me (I2C eeprom, could be connected to SoC). S24C50 (number 1) could also be a good candidate (I2C eeprom), but its position is surprising to me (far from the SoC, and maybe connected to a tuner related chip). Could you take a higres photo of these area s...

The other one could be, but I cannot read its reference to confirm

Ok.. I'll try to take clearer pictures of the chips and post them A.S.A.P., what's the reference that I'll should be looking for?

UN46C7000 LED bricked with service menu (changed the model)

Hi guys, I changed in the service menu the model of my tv (UN46C7000) and now I can't do anything. It turns on and off by itself and I think the only solution is to reset the eeprom but I don't know where is it.. here are some pictures of the main board, hopefully someone can help me find it. http:/...
