Hi, looking at this TV set, I can hear the audio, LEDs/backlights are on, but there is no video, here are some details...
Panasonic TX-48CX400B
17IPS20 power board and 17MB100 mainboard.
With HDMI source, I can hear the audio fine, but I can't see any video.
But the LEDs seem to be on, I can see the light coming through the holes on the metal plate at the back, that the circuit boards are attached to, and I can see an even layer of light on the LCD panel at the front.
The TV was on this afternoon for a few hours, audio continued to play, while the LEDs stayed on. When the TV is left on without a video source for maybe 5 minutes, the backlight/LEDs switch off.
I've attached a photo of the back showing the light getting through the metal plate, I'm thinking I'm not having a problem with the LEDs, but elsewhere.
I have read other threads with similar/same power board, but those problems were saying that they could see images on the LCD panel with the aid of a torch; I don't think I'm getting video to the panel.
What should I test first? It might be worth a bit of time if the panel is ok.
Thanks.
