[SOLVED] Loss of Video during Boot - 15.2 - Xbian add-on error

[StartledCat]

I thought it time to upgrade (with the 14.x updates not performing as they should)....so went of the latest img 2015-10-31.

But, during startup, the boot screen switches off near the end of the Loading Kodi splash screen....tried the other video socket on the pi, but still no joy.

Checked the config.txt files on both versions - they are the same...the 14.x boots fine and displays ok, 15.2 starts off ok, but then loses the display (still getting sound).

Thought it might be the card, so tried a trusted one - still no joy.
Reverted back to the previous img - still not joy.

To recap - starts off ok but then drops the hdmi video.

Raspberry Pi 2 - HMDI->RCA->Panasonic TX-26LXD1

Power all ok - known to be working with the same config.txt file....so what has changed? KODI? There must be some setting I've not found that can be set on sd card in this or another file?
