Question about Samsung DynaFlat TX-P3076WH 30" TV

Searching for signal, component connection

Lately, when I watch TV for about ten minutes the TV starts to search for signal.  After a few minutes the signal comes back and there is no problem for the rest of the day.  At first I thought it was a problem with the cable box, but my DVD is also connected via component cable and the next time it happened I tried to play a DVD.  When I switched from cable to DVD connection, it would still search for a signal.  The set is about 2 years old

What could be the problem with my tv cause it searches continously without finding any thereafter remains on channel 0 with no image or sound.i have changed tuners but that doesnt help.plea

There seems to be an incompatibility between the TV's setting and the antenna's input.
The TV doesn't see the antenna connection and keeps searching.
Somehow you have to get the TV's 'cable' setting in the menu to 'over the air'.
Is there a clean signal coming to the TV? Sometimes a cable can be compromised where the signal never reaches the input connection. Check both ends or at least replace the cable temporarily.
Last but not least, the TV maybe set to a PIP (secondary tuner with a picture in a picture) and the tuner is not electronically connected.

My Sanyo Ds27910 when searching for channels it says no antenna detected. what does this mean?

If you see thus, check the antenna connection for firmness first. If it seem correct, the tuner to your set is faulty. Does not process the RF signal. There is no repair to this, other than replacement. Contact any service technician to replace it. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.

Only response of TV model BH2404 with on switch is (searching for signal)

The tuner to your tV should be suspected. But before make it clear, you should check all the voltages coming to it.

When I turn the tv on (vega fd trinitron) the scren is all snow. There is no signal.

Have you tested it with auto tuning progremme process. If it snow there, your TV may be working properly. Sometimes its signal input path is not Ok. Without any signal, all TVs may show either snow, or a plane blue raster if its blue back function is on. You just do the automatic tuning process once again after connecting it with an external or internal antenna. There is a socket provided there in the back side of your TV, and marked as VHF/UHF. Connect the signal source to it first.
And set your TV to autotune by slecting it from the menu of your TV. The TV will search for all the channels available at that time, and after searching is completed, it will stop and show the first channel received. Afterwards you can chage or delete or skip unwanted channels. You may have its manual with you. All the descriptions are there in that manual. Ok.

TV is hooked up to Time Warner DVR when I turn on the TV it shows searching for signal but will not allow me to change channells

It will not let you change channels until the signal locks on. If it just keeps searching for the signal, look for a reset button on the dvr. If not, pull the power for 20 seconds to reset the dvr. IF it still wont find a signal, there is a major problem and you should call your satellite provider.

Auto Search Function won't work...."can't set auto search"

Make sure that you have the cable option set correctly before you do the auto search. If this is set to "AIR", you'll only be searching for an analog signal. Hope this helps.

Tv problem

Hi there!
Considering the age of the unit, my sugggestion would be to replace it. Dust normally collects inside on the components which in turn causes overheating. It could really be anything from loose joints on the main board to Line transformer or tube arcing over. Static interference from an external electrical source could also be the culprit. Check the mains for good connectivity. Good Luck,JUS004

Multiple video inputs

Unfortunately, you cannot use the connectors at the same time. The S-Video connector overrides the standard video connector. This is why they share common audio left/right inputs. If you could use them separately, they would each have their own set of audio inputs. (S-Video does not carry audio signals on the cable.) I'm assuming that you are connecting your Satellite as an input to your VCR, and then your VCR to the TV via a video connection. The VCR passes the satellite signal through unless you are watching a tape, then it overrides the dish signal. You have a few choices here: 1. You can connect the coaxial (RF) output from the VCR to the TV, and watch the satellite and VCR on channel 3 (or 4). You can then connect the DVD via S-Video, and watch it on "video". This is the simplest solution, and provides the best picture quality for the DVD (with this TV), but lower quality for the dish and VCR. 2. You can connect the DVD player via RF (if it supports that), watch the DVD on channel 3, and connect the VCR via video. This will make the DVD picture quality terrible. 3. You can replace the VCR with a combo DVD/VCR unit. You can then connect the S-Video out from the combo unit to the TV. This is a more expensive solution. 4. You can replace the TV with a model that includes more inputs. This is the most expensive solution, but will allow you to watch your DVD over component cables (very high quality) and VCR and dish over S-Video. Ironically, the obvious choice, connecting the DVD as an input to the VCR (as a pass-through) simply WON'T WORK. The signal put out by the DVD player is "copy protected" (using a system called MacroVision) which the VCR will refuse to play, even as a pass-though. Best of luck with this. Given that you are trying to make this all work without replacing equipment, I recommend option #1, until you decide to break down and buy a shiny new HDTV. They are coming down in price every week, but only you can decide when the time is right.
