I don't have Oscilloscope in reach..
Is it ok to search for TX (only) by trying all possible pins?

I don't think its the correct approach because the conductors of each pin on the other 3.5mm plugs are different on each plug... And I get 0V on all the pins of the suspected EXLINK...

You mean to desolder them and check? I prefer in a cleaner way...

Hi, I have a board like this, the only difference is that "1" is unmounted, so I have two 3 pin triangles like in "2", I'm thinking that "1" is the EXLINK and because "1" is unmounted I need to solder RS232 -> USBCOM to it, Does anyone know what is the structu...

I saw EXLINK_TX and EXLINK_RX but there are no solder pins next to it! I tried the nearest pins, none worked, (I also tried the pins of the unmounted 3.5mm where ex-link used to be in older models). BTW in the Service menu, in the Sub Option i have "UART Enable" option should it be ON or O...

Thanks, savan. What is micom_tx and micom_rx? I don't familiar with this term

TTL doesn't work on J/K using RS-232, check new wiki page: https://wiki.samygo.tv/index.php5?title=Ex-Link_Cable_for_J/K_Series The wiki is incorrect, There is no 3.5mm port that can be connected to, I opened the TV case, I need to solder the cable to the unmounted 3.5mm port, And the points where ...

Thanks, I see i have two unmounted 3.5mm ports on the main board, one of them is probably the ex-link... each port have two 3 metal surfaces in triangle shape(probably one triangle is TX and one is RX) and a hole (probably for GND), when I checked the voltage on those metal surfaces with multimeter,...

Hi, I want to know the latest firmware version (of the latest Series) that it is possible to decrypt without getting the encryption key from the ex link.

Thanks.

Also do you know how do I enter service menu in order to change RS232 UART mode to debug mode? I dont have [FACTORY] button on the remote nor [ INFO ] button
