Can a low HDMI signal effect the TV setting?

pacsailor -- Wed, 06/30/2010 - 14:40

I have a Samsung A32LN450 TV, connected to a H21 Directv satellite receiver via about 40ft of HDMI cable. It worked well at first, then the TV background got inverted color that is became a white background and all colors got inverted. I unplugged the HDMI cable and when turning the TV on it still has the white (very light gray) background. I replaced the TV with another Samsung TV A32LN350, it showed the correct picture for about 2 minutes, and then the background got inverted as well so I have a very light gray almost whitish background even after I unplugged the HDMI cable.
Could it be the low HDMI signal causing an internal switch in the TV to flip? how to reset the TV back to its original setting? I tried going via the TV menu and selected reset picture to factory settings but that did not help.
Is there a recommended HDMI signal amplifier to purchase, and will that help restore the TV to the correct state?

There is no mechanism for a low HDMI signal to produce this permanent effect. You need to explore other possibilities including a spurious and/or higher than normal signal from the receiver thru the inputs and/or grounding issues. Is this happening only thru the HDMI inputs? What does the Manufacturer say??

The signal could not be too strong because it is going via 3 ft HDMI to a wall connector, to 30 ft HDMI, to another wall connector, then to a 3 ft HDMI to the TV. The TV was working fine when it was connected to the satellite receiver via only 6ft HDMI. The whole idea was to place the equipment in a closet int he hallway away form the TV. I just purchased an HDMI extender which is actually a signal amplifier, but I did not hook it up yet.

The manufacturer said that they have not heard of this type of failure.
