Samsung HD UE55ES8000 HDMI issue

[Keeno]

Hi all, New to forums.

I wondered if anybody could tell me a probably cause or solution to my problem. Am experiencing problems with TV with HDMI ports. They seem to connect for seconds then video feed begins to blink & I can't seem to detect the problem. I've tried different sources, DVD player etc but it's torture. I've done a reset on menu. Is this a hardware problem or software/firmware.

Regards,
Adam

Maybe a silly question but have you tried more than one cable and is this all hdmi ports?

Hi MagicB,

Yes all hdmi ports whats strange is it gets the signal fine then struggles to display it and blinks. Haven't tried another HDMI cables but happens with both hdmi cables from skybox & dvdplayer. Not sure if its software related or not as am frequently checking for updates or its actually the mainboard/internals. WIll try a few different things and see I suppose

Hi, This could be a cable problem. Cheap old HDMI cables dont support HD, you need to make sure you have a decent one that complies with "High Speed + Internet". Its worth a try. Regards Mick

Sounds very much like a connectivity problem with the HDMI cable or connectors or port.

The problem is caused by the processor in the back of your TV.
The processor dissipates to much heat, the causes the HDMI to malfunction.

See the above site, it is in Dutch.

Pictures says more than thousand words.

The temperature on the cover can easely reach 55 -60 Deg C.

You can feel it clearly by hand.

The inside temperature in the processor and PCB will be much higher.

After startup and the processor is cold, the hdmi will work perfectly.

After 15 minutes the temperature is getting to high.
Solution is:

install heatsink on processor

use small pc fan

Ask Samsung to write better software which will increas the processors efficiency and improve the temperature.
