Hello everyone,
Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
Anyway I still fully expect that there has been something seriously damaged about that panel, but I am here to understand whats going on.
What is really putting me off is the fact that there is no sound. With a damaged panel I would either expect a boot loop or working sound.
But maybe that expectation is wrong for the particular model?
Heres what I see step by step
- the device reacts to the power button on backside and remote
- backlight turns on full brightness and dimms down a little after a second during boot
- device stays on, no boot loop
- screen stays black
- Unplugging either side of the screen cables from the mainboard (no seperate T-Con on this one) does not produce a half picture
- Plugging a HDMI source (FireTV Stick) into HDMI1 makes the TV react with change s in the backlight brightness
As I said, I would put my money on the panel beeing damaged given the history of someone with no experience working on such a big screen, if only there was sound.
I plan to spend some more time to inspect the panel in daylight and look for clues of physical damage.
If anyone has any idea what else I could try, I would love to hear.
For example is it possible that this particular model shuts off sound when a damaged or disconnected panel is detected?
Best regards
