Hello,
I changed several things in service menu. In SVC menu i changed IPTV and SVIDEO numbers, after that My tv is in boot loop mode.
It shows only Samsung Logo on screen, and after about 20 seconds it restart.
I tried to short SDA+VCC pin and turn on tv - but without success.

Can You Help me with this problem?

If you did not trigger micom, then eeprom reset must help. It can be you are not patient enough as this procedure often needs many tries until success.
