Hi
After a internet tv update ,
my tv reboots to the last channel it was. I tried everything but no luck.
So I think that the last step is to reset eeprom. Is there someone who tried to this tv ?
If so , can someone to show me which is the eeprom soc ?
Values of service menu are welcome too.

Did you check https://wiki.samygo.tv/index.php5?title ... PROM_Reset ?

p.s. poor image quality. I cannot read any labels on chips. Please write down and post here 8-leg chips. IC number and all what do you see printed on chip.

Thanks. juusso for the response. I read the wiki but these boards doesn't look like mine. The bad is that in the 8 leg chips the letters are gone. I 'll open tv again to see if my daughters can read cause I am old. Thanks again.

Hi again. I have some more detailed pictures.
I think that is the chip in the 2 last pictures. The 42568RP. But I can't find any datasheet about this.
If is it, the white triangle is the number one ? If so I have to connect 5 and 8?
