Question about Protron PLTV-32 Television
I have a PLTV 26 LCD TV and the picture quit but the audio still works. I just replaced the inverter board V400-301 and still no picture. I* was told that this should fix the problem but it didn't. Any suggestions?
I would suggest to check the 24 volts from the power supply to the backlight inverter board. If the voltgage is missing or lower then 20 volts, the power supply is defective. If the voltage is correct, you might have a defective light inside the TV behind the screen since you've replaced the backlight inverter board; you now the failure is not there. The lights are connected to the backlight inverter board.
Let me know if you need further assistance.
