"Blaupunkt" 40/2331-GB diagram?
« on: April 25, 2018,09:52:20 »
Hi people,

I have a "Blaupunkt" TV with no led backlight.
The main (only) board is a TP.MSD309.BP710. Does anyone know where I can get a diagram? I've searched to no avail.

I have a s/c across a diode right at the led connectors (no ref). If I lift the diode the short remains on the board. IE the diode checks ok.

Update: Replaced OB3350CP which did have s/c (Thanks Jordan), still no backlight.

Bit the bullet and stripped the display (nightmare) to find one led at fault.
