I didn't do that test, as I preferred trying the "non-invasive" test with turning down the backlights first. I think I will give replacing the LED-Panel a try, since the seller seems to offer return service and guarantees for functioning LEDs.

I will definitely give this a try, just to make sure I got this right: If the mosfet...

Hello Everyone!

I am currently trying to figure out a solution to a "sound, no picture" problem I am having with my Telefunken L48U300M4CW tv (48inch edge-lit LED TV) and I haven't been able to certainly determine the fault in the set based on my observations. Shortly after purchasing this tv it began turning off the screen after random, varying periods of times, while continuing the sound. A restart would always fix...

I am a german student in the city of karlsruhe, majoring in mechanical engineering. Due to my mechanical background I have no clue what electricity might be whatsoever, but I'm confient I might get a clue if I read the stickies on here closely enough!

actually, even though I started out looking for a fix for my current TV (which was used when I bought it and I kind of suspect the seller...
