I also changed Control > Sub Option > RS-232 Jack -> Debug ^ Ex-Link Cable (service port TTL serial) https://wiki.samygo.tv/index.php?title=Ex-Link_Cable_for_C/D/E_Series_and_BD_players {image: 800px-TTL-232_E_pinout.jpg} 3.5mm jack "service" on TV: * 1 - tip - Tx * 2 - ring - Rx * 3 - ring - GND If you have TRRR jack, just use first three pins. Others are not connected to anything in TV. To find ground pin check continuity between your jack breakout and USB connector. One you found ground, pins from it towards tip are Rx and Tx. I also measured Rx and Tx pins which where around 3.3V, so safe to connect to usb serial. ^^ dump of serial console It's 115200 8n1 3.3V serial console: {file: samsung-UE40EH5450-serial.txt.gz} ^ top-debug menu https://wiki.samygo.tv/index.php?title=Top_Debug_Menu:_TDM ^^ Console unlock and TDM codes MStar (Series 5 & 6): 1198282 20089999 Just blindly start typing numbers: .pre 20089999 ==================================== [ TOP Debug Menu] ------------------------------------ 1 : SubSystem Print On/Off 2 : Platform Print Setting 3 : TD Print Setting 4 : Performance Print Setting 5 : Sdal Print Setting 6 : Sdal Trace Setting 11 : TD Debug 12 : SubSystem DBG 13 : SubSystem Info Print 21 : Louvre Print Setting 30 : Auto Lock DBG ------------------------------------ 70 : Jade Debug 80 : PVR Debug 81 : CSP debug ==================================== 99 : Exit ==================================== .pre ^ service manuals http://tel-spb.ru/tv/samsung-ue40eh5450 |
