When powering on my vu 32 inch full hd led TV backlight flashes once
When powering on my vu 32 inch full hd led TV (model- 32d6545) backlight flashes only once and thereafter the screen goes black with sound only. I checked the voltage on led supply pin. When I power on the TV and the “VU” logo appears, the voltage is 76 volts but just after that the logo dissappears and voltage drops to 44 volts. What is the reason?
Это хороший вопрос?

Hi,
Shine a torch at an angle close to the screen and check if there is still an image there when the sound is on and the screen is black.
Can you view the menu screens OK?
It may be a software problem or a problem with the mainboard that is telling the power board to turn off the backlights.
Have you tried using different input/input types e.g. HDMI, AV, Component video co-ax to check if the TV works OK?
What else have you tried besides testing the backlight voltage?

Yes. Images are ok with no backlight. I have also checked all the connections.
