Samsung 40 inch lcd 550 hdmi port trouble

by isles81 / September 18, 2008 2:19 AM PDT

I have my cable box connected via HDMI, and my two component inputs are used by an xbox and nintendo Wii. While watching cable (HDMI 1), the picture went out and I got a message that there was no device connected to that input. This clearly wasn't the case. I've since tried all 3 hdmi inputs with different devices, and it always says nothing is connected to that input, and accordingly won't even let me select the input as active. My component inputs work fine. I have a hard time believing that there was some random problem with all 3 hdmi inputs at the exact same time for no reason. Any thoughts?

I also tried a different hdmi cable, it's not the cable.

What is probably happening is that your cable box is sending a signal to the television that it can?t necessarily read. You might want to see if there?s a menu (sometimes hidden, requiring a call to your cable/sat provider) that allows you to accept only 480p signals and higher.

The transmission of 480i over cable, or the switching of a high-definition signal to a non-HD signal may cause the television to momentarily lose the signal and cause your picture to drop out.

Keep us posted!

It used to work perfectly for 3 months before this happened. It's not the signal -- the tv doesn't even detect that a cable is plugged in to any of my 3 hdmi inputs. This happened while we were watching tv and had been perfect, set up the same way, for 3 months prior. I've also tried a dvd player, etc. It's something with the ports, not my devices or the cables.

Any thoughts?

I'm sorry to hear that you're having this issue with your TV.

If the television isn't detecting any cables plugged in the the HDMI ports, it's likely going to be a service issue. My recommendation would be to call the Samsung customer service center at 800-SAMSUNG the troubleshooting or repairing.

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
