LN52A750 - switching input to antenna

by R401KTJ / January 30, 2009 9:01 AM PST

Any input on why the TV keeps jumping over to do a channel search? I'm currently providing 2 HDMI inputs to the tv (HD cable box and Blu ray. While watching either blu ray or cable, it keeps jumping over to the "air" input and begins a channel search. I've tried the auto search function thinking it just need to complete this setup step. the entire goal was to use HDMI for everything, not a coax cable!!!

I just did a firmware update and no change. I called samsung and am waiting on a response from a local tech but haven't heard anything yet. $2700 this shouldn't be happening.

Channel Searching....

I'm not sure why that would happen.

So from either input (HDMI 1 or HDMI 2), it will just go to antenna and start searching for OTA (over the air) channels?

Are you using a programmable remote perhaps?

I had the exact same problem you're describing with my first LN55A950. I experimented for a couple of WEEKS with different inputs/sources, etc. It was simply a defective TV. The replacement that was sent has never once had this problem, so it's NOT your other equipment or a cable or a setting. Your TV has a defect. The sooner you get a replacement on its way, the better. Wish I had a happier answer!

I just tried a "Reset" but it keeps doing it......

Thanks again,

There are one of two things I think could be happening.

1. The pushpanel on the front of the television is somehow initializing a source switch. I'm thinking that it might be a tad oversensitive and just switches to your tuner randomly.

2. There could be an internal board that needs to be replaced.

I would definitely call 800-SAMSUNG and schedule a technician to come out and inspect your unit. I can't give a definitive answer at this point, but I'll leave it to those hypothesis.

No ghost jokes. I promise. Happy
