Question about ViewSonic N3251w 32 in. LCD HDTV
I have a similar problem. Not able to view any input or the Menu screen. On the way to buy new TV but would like to fix this one if possible....Been a good set for the past 2 years!
This failure could be due to a backlight inverter board or the power supply is not providing the 24 volts to it.
The way to fix it is by measuring the voltages from the power supply to the backlight inverter board, if the voltage is present then the backlight inverter board is defective and will need to be replace. If the voltage is lower then 20 volts, then is a power supply failure.

Let me know if you need further assistance. I repair power supplies for all LCD models.
