[fixed] No connection to TV Server (1 Viewer)

[SiLenTYL]

On the PC that has the TV card installed, open MP Config and TV Config (from the shortcuts). doublecheck u have the correct TV->TV Client name (should be the same name as the TV database name (for me its my PC hostname).

 

[TLD]

Yes it has the same IP number and the client on the TV server will show the Groups,programs and channels if i go to "Channel" in the TV section of MP

I had no connection to TV server error and would freeze start up of MP, What I found it to be in my case was that I didn't check the default Database, Once I reinstalled and set it too mysql it all worked again.

Probably the issue is that _channelList is null. A better fix would be to add a check *inside* PositionGuideCursorToCurrentChannel() like so:

if (_channelList == null)
{
  return;
}

...or alternatively, have some logic to set the _channelList as the first channel group in this case.

Edit: _currentChannel could also be null, so that should be checked too.

For testing, I added

if (_channelList == null) return;
if (_currentChannel == null) return;

at the start of PositionGuideCursorToCurrentChannel

and this now works fine when there is no channel or group specified in MediaPortal.xml, and with or without 'always hide all channels group enabled. So I think this covers all scenarios.

Obviously this can be combined into a single line, but it is basic error checking and seems safe.

So I guess what we need is, at the start of PositionGuideCursorToCurrentChannel

    private void PositionGuideCursorToCurrentChannel()
    {
      _cursorX = 0;
      _cursorY = 1; // cursor should be on the program guide item
      ChannelOffset = 0;
 
      if (_channelList == null || _currentChannel == null) return;

Could a dev ( @mm1352000 @Sebastiii ?) please make a GIT branch for this? The mantis is

Here it is. This one has added logging. From this, it seems that only '_currentChannel' is null, so perhaps we only need to check this.

Note that this logic (opening EPG at last tuned channel) wasn't implemented for radio EPG, so there is nothing to do there.

Wow there is so many replied that i didn't read them all an to update my thread i finally fix it as some says by going to channel first, select a channel and after that the connection to the TV server was just fine so it's definetly a bug with the 1.3.0 version since i think i had the same problem with the Alpha version.

I have the same problem. I want to connect my 1.3beta client to the 1.2.3 server. Is that even possible? Anyway, I get kind of the same error as in the TS. This is my connection string: <DefaultProvider name="SQLServer" connectionString="Password=*******;Persist Security Info=True;User ID=sa;Initial Catalog=MpTvDb;Data Source=192.168.1.13\SQLEXPRESS;Connection Timeout=30;" />

Short answer no. Upgrade your server.
