Hey hi,

I wanted to turn off the buttons on the bezel (little kid in the house keeps turning off the tv), found somewhere online that it would be possible to do that by going into the service menu and putting the tv in hotel mode and turn it off there. Accidentally i think i also changed the tuner type and now it won't start up.

Its starts, the screen turns on for a second and then it quits and starts over. so it's in loop.

I haven't done any of this:

1. Have you installed the proper u-boot and kernel with network supporting?

2. Have you set rs232 to debug? Watchdog off?

3. Do you have an exlink cable? What is the output?

I have, however, tried resetting the eeprom as mentioned here: viewtopic.php?f=4&t=3744
It didn't help, still won't start up...

Can anybody give me some advice, or should I start saving for a new tv?
Thanks,

I've put together a picture and diagram showing it.

Like i said, we tried that and it didnt work...

Any other suggestions?

buy another mainboard. You can take one from B650 and get your TV slightly upgraded for ~100USD
just you need to do small investigation on mainboards, we have success on upgrading B550->B650.
Your TV is LED TV(?) and probably sizes/connector places on back pannel or so on are different. Anyway, you`ve got an idea

I don`t know any other way for unbricking except those you`ve seen on wiki.

Thanks, do you know where i can buy a new board?

ebay, http://euroservice2000.abc24.pl/ and so on. Input mainboard number you`re looking for and you get it. You can also ask on your local samsung repair centre. If you want cheaper, you can get second hand mainoard.
