Looking for Answers about samsung LN-S4051D?

The last 3 days it was very hard turning the TV on. We would have to hit the remote more than once for it to click on. This evening we lost sound. I was able to shut the TV off and it had no problem starting right up. Then the sound went again. I shut the TV off and from that time on, it will not turn on. The red light indicator will flash, the TV clicks like it wants to turn on but it doesn't.

One will not turn on at all. One is very delayed in turning on. One is delayed and now both HDMI connections have stopped working.

I do not like having to use the small box from cable company but tv is still in good shape

I recently purchased a 55" 3D LED SmartTV model. I tried to hook up (HDMI port 1) to a laptop equipment with HDMI port. But, the TV shows no input signal. I then tried to connect the laptop to other HDMI ports but still didn't work. I also own an older Samsung 40" LCD TV. I have been connecting the same laptop and HDMI cable to this 40" TV without any problem.

Could you tell me what could be the problem with the 55" LED TV?

It was working fine one day then the next day all i got was a high pitch sound and nothing else. Ive tried all the settings and yet, still no sound. Is there anything i can do to fix this problem?

when i press the power button, the TV wont turn on. There is a series of "click" sounds simliar to what i would normally hear when the TV powers up (although when it worked...it was a single "click" sound. I am thinking i need to have the main PCB or power Supply board replaced (or both). Does that

For model number LN-s4051d

I do not know how to get mt TV to work properly. Can you please provide instructions on how to do so?

TV will not turn on...continues to click a few times when on/off button is pressed...and if not recalled how much would a replacement power source be?
