Question about Samsung SPN4235 42 in. Plasma HDTV

Open Question

Weak or no signal on plasma tv hookup

Can't get a tv signal through new Samsung HPT4264 Plasma TV. I've tried various outputs from the D11 DTV Satellite box and TV inputs but nothing works. The S. box has coax coming and going and the tv has 2 inputs for coax (air & cable) but neither works. The manual says various other types of connections will work but does not mention coax. I've contacted customer support from DTV and Samsung. Got nothing but finger pointing. My question is whether this new tv will work on old fashioned coax cable or not. My satellite box is not HD. If not, why are the coax inputs on the back of the tv? Am I not doing something right? My dvd/vcr player works fine on the S-Video output and tv input for it. Just can't get a tv signal from the cable box.

SOURCE: Samsung 42" Plasma HDTV cable hookup problem

There sould not have been sparks. Check the following: Using a voltmeter check between the cable itself and ground. There should not be any reading (anything less than .1V is normal). Check again between the inner hole of the RF connector and the outside part. Again there should be less than .1V. If you read any voltage at the RF connector, the TV is faulty and should be exchanged. If you read voltage at the cable, have teh cable company check again.

SOURCE: lcd tv hookup

Ive got 3 samsung tv's (lcd, plasma, DLP) and I use HDMI cables on all of them. Its the only way to get the full potential out of the tv. When you use the red/white/yellow RCA cables the signal is anolog aka "old technology". Component cables are good but HDMI is the best. HDMI is a digital signal and thats what all the components that go with the tv should be run on. If your dvd player does not have an HDMI output I would suggest getting one that has that output. As for the cable box most require you to upgrade to digital cable in order to get one with an HDMI output. If you dont want to spend the money on new components and run what you have now the picture will stay mediocre at best. Good luck hope this helped

My cable box is hooked up but no signal can u tell me whats wrong


If you hookup your TV directly to the coaxial cable, bypassing the cable-box, do you get a few channels? If so, then the coaxial cable is carrying a signal, which is good.

How are you hooking the output from the cable-box to the input(s) on the TV? Coaxial output port on box to coaxial input port on TV?
Red/blue/green "component" outputs on box to matching inputs on TV? Red/White audio outputs on box to red/white inputs on TV? HMDI output from box to HDMI input on TV?

You have to "tell" the TV which of the inputs:
* coaxial (with TV set to Channel 3 or 4)
* component
* HDMI
to "listen" to.

Vizio vm60p hdtv scanning problem


I had the same problem. Change your input to dtv even if you are using coaxial input. Then go to the menu screen and select tuner settings. Dtv setting should appear.

I get a weak or no signal message on my new Samsung plasma. I'm using coaxial to my cable box. The cable works fine because I can see the vcr when it plays. I have it set to cable on the right channel...


In this case, your VCR becomes the cable channels tuning device for your TV, the better connection should be from your cable box output to your antenna/cable TV input with the coaxial cable, surely, your TV has a better cable tuner than your VCR, to connect the VCR to TV you can use its AV outputs to an available AV inputs of your TV, you can get a better sound and picture in this way.

I doubt that moisture damaged the SMPS bd.
There are many circuit boards in your set and it will take a trained samsung tech to find the problem.

No signal on screen in VCR mode


I assume your plasma set has one or more auxillary (component) inputs, and to one of these is where you should hook in the VCR. You will have a video input jack, and a set of audio input jacks (probably 2 for stereo) for each of these aux. input sets. While exact setups differ, depending on your cable box(es), DVD players, and whatever other equip., a likely hookup is from the VCR video & audio outputs to one set of the aux. inputs on the plasma set. When you want to use the VCR for playback, you must select that particular aux. input with the plasma remote. Some of the hookups these days get complicated by all the equip. some have, but the above is at least a start. Thanks
