Currently trying to re-set eprom. Hopefully I'm connecting those right?

I can see the logo, then the connect source can make 2 moves then it re starts. In this time I can very briefly enter menus but have no real time to do anything.

After I do the eprom thing, the menus are still Swedish, isn't that suppose to reset to English?

Disconnecting the main board keeps the TV from restarting.

Dose this isolate the issue to the main board?

I also read about, when reseting eprom, there is suppose to be a white flash then a restart. I do not get this flash if whitnes

I mange to make a factory reset using the service menu. Still no go.

Nand flash seem to be the next logical step.

This video on YouTube show very similar error. Now to find someone to do this as I do not intend to buy a device for several 100$ that I only use two times.

Bought a nand flash of ebay, with software pre-installed.

Will report back, it has to be sent from us to Sweden. So it will take some time. But I will be back.

Thanks for posting and sorry you`re left alone with your problem. Can you describe what caused your bootloop? If failed sowtware upgrade, then replacing soc eeprom won`t help.

Bought the TV second hand, she told me one day it just stopped working like this. Boots then about 10 seconds after the logo in it boot loops.

Bought a new nand chip that is soon here. Hope that will work.
It is said to be pre programed.

But, which settings should I backup from factory settings if somthing goes wrong. I have time to enter them but not for long.

it must work even with empty eeprom. No need for backuping something extra.

I remember reading somthing about setting up font color and other settings. Can't find it though.

Those settings you will be asked to enter on successful boot. If such occurs.
