LG LCD TV HDMI PORT FAULTY

[RossMoodley1967]

LG LCD TV picture comes on intermittenly using hdmi port.The sound is on permantly.The hdmi ports looks fine and soldered in securely.The 3.4v coming to the main board is not present(not sure if will affect the hdmi port or where that voltage goes.)The hdmi cable is fine because it works on another tv.The ceramic caps connected to the hdmi controller ic is reading 39 ohms.Could the hdmi controller ic be faulty(feels very warm to touch).The RCA jacks work normally .Thank you in advance for your assistance..

The ceramic caps connected to the hdmi controller ic is reading 39 ohms.

But this is bad, you will have to change this controller!
Check the resistance of the HDMI signal lines, there are 8 of them relative to ground.

Sorry for my ignorance , by signal lines , do you mean the signal lines at the HDMI port pins ... i am counting more than 8 pins. thank you.

There should be only eight of them and they go to the controller.
