Various firmware bugs (UN46C6400)

by aud78 - 12/27/10 2:07 PM

I couldn't find a place to report firmware bugs on Samsung web site, so posting them here. HDTech, would you mind forwarding these to development team...

TV model: UN46C6400
Firmware: T-VALAUSC-1032.0

1. Spectacular crash when initiating DLNA playback while watching Netflix

To reproduce: start watching any movie via TV's Netflix app. On Windows 7 PC in the same network, rightclick on any video file, chose "Play To", and then chose your TV. Wait a minute or two

Result: all kinds of colors and patterns appear on the screen; elements of Netflix video are scattered in multiple locations; more colors flicker; then irrelevant error message is displayed and finally TV shuts off

2. Media player crashes if H264 video is encoded with "Animation" preset

To reproduce: encode any video using H264 codec with "Animation" preset on. Place it on USB drive and plug drive directly into your TV. Start playback using media player

Result: playback is distorted, often skips and lags, and after a few minutes media player crashes
Note: exactly same video plays just fine if source is DLNA rather than physically attached USB drive

3. Incorrect error message when trying to launch any App before IP address is obtained via DHCP

To reproduce: turn TV off and then on again. Immediately launch internet TV and then click on any app.

Result: Error message says "Service is unavailable due to network interference". This error suggests that there is IP address conflict on a subnet and TCP/IP can't work. Although what is really happening is that TV had not yet obtained IP address from DHCP server; waiting 10-20 seconds resolves the issue. Error message should say something like "Connection to the network hasn't been established yet", or, better, simply show "Connecting..." and launch the app automatically once IP address is set.

4. TV shuts off within seconds if left on "PC" source while PC is off

To reproduce: connect PC to TV via VGA cable. Make sure PC is off. Unplug all other sources from TV (like antenna or HDMI). Set source to "PC". Turn TV off. Turn TV on again.

Result: you have only 1 or 2 seconds to quickly switch source. If source is not switched, TV shuts off within seconds. It is impossible to launch Internet TV - it starts launching but then TV shuts down.
