Re: Samsung LE32R88BD/ BN44-00155A

Success - Thanks for the help. LNT 3242 still failed after recap
Problem was an open on one of the inverter transformers.
Measured across the CCFL connectors all were 3.5K except one was open.
Replacement $ 7 from china. Replaced failed transformer 2 sec black fixed.
Also fixed a Samsung 920nw 2 seconds to black due to open
return wire on a CCFl as per this forum. Recapped, still failed,
very gentle tug on the return wires and one came right out.
Required skill full repair but worth it fixing free...

1. Have a LNT 3242 with BN44-00155A that goes into protection mode, backlights flash
for two seconds then backlights shutdown, power is still on. Looks like the controller
board is detecting a fault or low voltage and going into protection mode. Suspect the
problem is low voltage on the 13 volt supply.

2. The 13 volt power supply only reads 11.58 volts right from power up BEFORE
the backlight is even enabled.

3. All other supply voltages are correct, 3.4, 5.3, 5v STBY, and 24 volt...
