Problem with LN-T405HA switching between inputs

by naveena79 Sep 19, 2010 1:49PM PDT

Hi,

we have a Samsung 40" LCD TV with model LN-T405HA, recently it started to switch between the different input sources like HDMI1/HDMI2/component2/Air automatically without pressing any button.

It switches automatically when we will be watching the TV. Once the the hdmi1 switched to hdmi2 then it will search through all the input sources and finally stucks with out displaying any image with Air input source (antenna) and displaying hte no signal message.

If I disconnect all the hdmi ports then it just abruptly shifts between component2 and air. we are not able to understand what is happening?

Any help in this regd would be really appreciated.

Thanks
Naveena

Problem with LN-T405HA switching between inputs

naveena79,

I'm sorry to hear that you're having trouble with your unit.

Disconnecting all of the HDMI ports by default will take a normal working TV back to the AIR input.

Based on the symptom, it sounds like either the remote's source button is engaged, or the bezel SOURCE button is either engaging or something nearby is causing interference with it.

To check the remote, you can shine a camera phone or digital camera to see if there is a constant light on the emitter of the remote. Here's an example:

If it's the bezel, you might try tapping the SOURCE button on the TV's frame to see if that stops the symptom.

If you're seeing a constant light from the remote, then the unit may require further troubleshooting or service, and you can reach that at 800-SAMSUNG.
