Ahh - I didn't realize there were two serial modes. (Although I suppose I did read some mutterings about serial control working without any mod in the service menu.) Good info. Shoot - yeah - the ultimate goal was power-on. Prior to this, I was experimenting with Wake-On, etc, before finding this fo...

.. And sure enough, it works just fine direct serial. I guess my serial-ethernet server is junk. I'll have to think of something creative to do with those TTL converters. Any idea if this series display doesn't use the regular samsung serial commands? I've only been poking on this code for a few min...

Aha! That's incredibly helpful. Yay for Jimmy and his hi-res photos and hard-to-find parts. :-) My port does say "Ex-Link", and I did start this whole effort trying rs232 direct, with identical results - same garbled data. So perhaps you're right about this being rs232 and not TTL. I'm rel...

My first attempt was direct rs232, which actually yielded identical results: Garbage data at power on/off. If this attempt had damaged the display, what would the symptoms be? Do damaged boards usually go dead, or could I have killed it in a way that it only pushes garbled data? FWIW, I am using a P...

Had slightly better luck with www.robotshop.com/droids-db9-serial-adapter-5.html based on a max3238E chip. When I connect the tip of the Ex-Link/audio plug to the RX pin of the TTL converter (plus ground), I see log output on my terminal app. I get a good burst when I power on the display, then a bi...

Hi folks, I'm guessing this is a routine question, but I'm looking for advice nonetheless. I've been trying to enable serial on my UN55C6500 LED display. I enabled "Diag" serial in the service menu. After a brief attempt going straight from RS232->Ex-Link, I discovered the need for a TTL c...
