So a small crew driver would do?

But I'm not sure where to find the proper chip on the mainboard. Can you maybe point me to the right one?

are you sure you have connected LVDS cable in proper way?

p.s. eeprom should be marked one on http://wiki.samygo.tv/images/d/d5/UA40C6200_full.jpg (you have same board, just with some more components on it, like CI interface...)

Yeah, it wasn't connected yet in the picture above ;-)

Is the EEPROM location identical to the C6200 example in the wiki?

Ok, just used a test pin to short circuit to two pins as marked in the wiki. But unfortunately the picture is still distorted and the tv is still stuck in the reboot loop. :(

I`m in doubts. Can be:
1. you haven`t proceed the eeprom reset procedure well and it didn`t worked. Possible even if proper made eeprom resed won`t help
2. Possible, that this board is not compatible to other hardware on TV (LVDS?)
3. Mainboard you got is damaged

You should search local serviceman to check it... I can`t help, this issue is out of my knowledge. apologies.

Maybe other our users have ideas?

@ sbav1?

No problem, you're just trying to help and I'm thankful for that.

I've put the original board back in and that one works right away.

Just a question concerning the reset process: Do the two pins have to be connected before the tv is connected to the power grid?

Yes, you have
-unplug from power
-connect two pins (sometimes there is no contact - pins may be coated) and keep it connected
-power tv and wait until LCD is light up
-release pins
-use remote control to power tv off to standby mode
-info menu mute power to get it direct to service menu

That's too bad. Just did another reset but with the same results.

Any guess as to what might be the cause of this incompatibility? The difference in screen size between the UE40 and my UE46?

Just an follow up question: What would be an alternative for me now? Get the exact same board type that others here have successfully used to upgrade from UExxC6000?
