HDMI Ports not working - is there a fix?

[jstiene]

Hello.

I have run into a couple TV's over recent time where the HDMI ports do not work but Coax does. Is there a reset to fix this problem or does this point to a defective main board? Just curious if there is a solution...

Thanks in advance!

Could be anything would need diagnosing, so no point replying with anything in detail.

I have seen a LG TV with the HDMI connector tabs not soldered to the board so only the surface mount pins were holding the connector in place. The connections would eventually disconnect or the connector break off entirely.

Depends on the main board. Load some pictures up so we can see something.

If none of the HDMI ports work I would focus on the HDMI interface chip, easy to damage plugging PC's in and out (especially ungrounded desktops which will have mains/2 on protective earth caused by Y-caps in PSU)

I've had luck on changing the 144pin HDMI switchIC on my LG main board when I lost all my HDMI ports, while all the rca jacks worked. Same goes for Gaming consoles, as the PS3 and PS4
