the old saying is that any issues will likely show up in the 1st 3 days if you run it for 72 hrs. if it dosent fail then it will last.
other than going to the show room and seeing if their unit does the same.
they will likely want to send a service guy to check it out and decide for himself.

SOURCE: LG 47" LCD TV - 47LC7DF Clicking Noise

I was told that these clicking noises (which happen on my Magnavox LCD too) were due to the "power required" at the internal switch. Seems that the power required to immediately turn on the TV is too much for a standalone household outlet, so it "surges" power in a series to get enough there. Hence, the clicking sounds are actually mini power surges to send more power to the internal circuits to turn the TV on.

If your set is like mine, these noises generally stop after a minute or two, correct?

SOURCE: My Samsung 50" HLS5086W wide screen tv keeps shutting off....

I have a Samsung DLP 61". The TV continued to turn off with no indications from the panel. I did some tests and determined the TV was not getting enough air circulation due to its poor fan inside. I installed a 110v computer fan on the outside of the vents on the rear of the TV to **** the heat out. Worked great and I have never had a problem since. Need further help or pictures let me know

It seems new TV.

But that kind of problem is related LCD panel.
If you can replace LCD inverter first.
then not working need to replce LCD panel.

When i turn it on it winds and turn off.


  1. Check the power. Don't be embarrassed if your problem is as simple as an unplugged power cord. It's better that you should discover this than pay a repair technician to come out to your house and find out.
  2. Isolate the problem. The main troubles that will crop up with a TV set are either no picture, no sound or both.
  3. Check the input setting on your remote control. If you have other devices connected to the TV, such as a video game system, those devices must be used with a different input setting than the input you use for watching programs or movies on a DVD or Blu-Ray player. Chances are, the kids were playing a game and forgot to turn the input back the way it was.
  4. Press the Input button on your remote control to return to the setting you wish to use. For example, the cable box might be connected to Input 1 and your DVD player might be connected to Input 2. Newer television sets have at least 3 inputs.
  5. Check the coaxial connection from your cable or satellite receiver to the television. The cable should be attached securely by twisting the round lock nut clockwise. Also check the power connections for the satellite or cable receiver. If either is unplugged, you won't receive a programming signal on the TV.
  6. 6 Make sure the video cable is securely attached to the TV jack if you have a home theater system. The video cable runs from the Video Out jack on your home theater receiver to the Video In jack on the back of your TV.
  7. 7 Check your receiver setting. Home theater receivers manage several components, so if you have the receiver set to operate the CD player but you are trying to watch a movie on your Blu-Ray player, you'll need to change the selection to Blu-Ray to watch the movie on your TV.
  8. Check the TV speakers to see whether they have been muted by accident. Press the volume button on your remote control or go to the Menu section and scroll down until you reach TV Speakers. Toggle left or right to turn the speakers on or off.
  9. Press the speaker button on your receiver to make sure your external home theater speakers are activated. Many home theater systems use external for their superior audio rather than the speakers inside a television.

We just purchased the 500 series Samsung LCD HDTV. We have dish satellite. How do we hook it up. We are unfamiliar with the different types via HDMI, DVI, Component Cables. Your help would be...


first things first. is your satellite box HD compatible? if so, there will be a HDMI output on the back. if not, there will either be your typical red yellow red jacks, or possibly blue green red component cables. if HDMI is available, it is the optimal choice. if not, you can still use this box but will not be able to utilize your tv's HD functions. if you are not running any additional home theater accessories, that is all you need to get your dish up and running. to clarify, if you can use HDMI, you sound and video all run through the one cable. If your satellite box is not HD, i highly recommend upgrading to one.

No sound


More than likely you need to go into your menu settings. Check to ensure that your TV speakers are enabled. The previous owners may had it hooked to theater system

Here is the manual:

When using the HDMI connections you may have to tell the DVD to output to that port.  Also you may have to connect additional sound cables from the DVD output to the TV.

I have Time Warner cable. I just bought a new Sony LCD HD tv and the sound and the video are out of sync on some channels - HD and non HD I am using a HDMI cable. Any solutions that you know of?


Yes there is a simple solution. First, for some reason., Time Warner cable boxes have SERIOUS HDMI issues, including no pic, intermittent pic and sound and the one that you are having. The easy fix is to hook the TV to the cable box using the component connections instead of the HDMI. Normally I would suggest getting the cable box replaced, but I have seen customers exchange cable boxes 3 or 4 times and still have the problem or have a new problem. Use the component connections and be sure to let me know if this works. If it does, be sure to rate this solution. Thanks!

Samsung Rear Projection DLP HDMI Captions


The captions are turned on in the cable box itself. If you have a Motorola cable box, turn it off then hit the menu button for the cable box. You will then see where you can turn off the closed captioning. Anymore questions email me tvtek@msn.com
