All HDMI ports no signal (ES8000)

[archit3ct]

Hello,

I have a Samsung UE55ES8000 and I got no signal message on HDMI ports.

I tried to swap ports, different cables, different devices, PS4, AVR, anynet on and off, left the tv  unplugged.

Sometimes its shows and went you turn it off and back on, no signal again.

AVR is connected and I change volume from tv remote and I see that on the tv, but no signal.

Hi

Have you directly connected a device to the TV and ruled out the AVR?

Are you sure the HDMI cables are plugged in fully.  Have you tried factory resetting the TV?  If it works sometimes and not others it sounds like a fault in the TV if everything else is okay.

Regards

Yes I tried factory reset also. And yes I tried the devices alone without the AVR.

USB videos are fine, aerial is fine, sat is fine. Only hdmi ports.

Frustrating..

Hi

Sounds like there is a fault with the HDMI circuits in the TV.  At a guess I would say it's probably a bad capacitor in the power supply to that area of the circuit. It might be repairable quite easily but the cost may be prohibitive if no longer under warranty.

Good luck

It is a thermal issue, caused by the processor overheating .

The processor is located on the same PCB as the HDMI inputs
