Sounds like tuner fault. Contact any service technician. Just do a reset to this set and check; before contacting anybody. There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

SOURCE: dvd picture

Make sure component cables match colors between Television and DVD player. It should be TV input to DVD output. Try to play at least two DVDs to make sure its not a single DVD that may be having an issue. Also, adjust your television's picture setting to make sure its set to normal. Also access your DVD players menu to make sure the setting are set to normal as well.If it doesn't correct the problem, use a different component input on your television. If problem persists, you may need to contact the DVD player manufacturer to see if its still under warranty and not defective. Good Luck.

I have a maganovox combo system, converter box, older model zenithe tv and rf modular. How do I connect all this to record and look at vcr on combo? I need step by step of hooking up all cords and plugs....


You dont need the rf modulator. Use a female to male rf, antenna cord and plug from the RF out on the back of your combo to the TV. Now you need to tune your TV on analogue mode until you find the dvd/vcr picture. Have the combo on when you're doing this.

I have a Samsung flat screen tv and cannot set up a n64


Upon looking up your tv I realize it has no composite (yellow, red, white) input. Without that you can not hook up your N64. There are other options though. You could buy an RF adapter for the N64 (Gamecube, Super Nintendo, and N64 cables are the same) but by doing so you will lower the picture quality a bit. Or you can buy a component to composite converter (like this but if you shop around you could probably find a better one for cheaper http://www.amazon.com/Component-Composite-w-Down-Scaling/dp/B003FJKHBU ) Lastly if you have a DVD player or VCR that has component cables you could hook that up to your tv and then hook the N64 into it. Good luck!

I don't know what channel to go to to be able to play my dvd player


where did you hooked up the connector wire coming from the dvd player, in the component input or at the RF jack of the tuner of the tv?. if you plug at the component input of the tv you will select AV1 or AV2 etc. in the settings. but if you hooked up into the RF jack you can select channel 3 in the tv but at this time you need to have manual tuned in the tv to get the signal coming from the dvd player or xbox.

I'm trying to hookup my Toshiba DR430KU to an older tv that require an RF Modulator. I get a skewded sideways picture. Does This DVDR compatable with a RF Modulator?


Probably not. Better picture results are achieved with either S-Video, standard RCA AV cable (yellow-white-red), or YUV component cable (red-green-blue) (component output does not have audio - this requires extra cable to be connected). The video via either one of these 'AV' connections is stunning (based on a standard 16:9 LCD TV using a Panasonic DVD recorder).

RF tends to be lower quality - as opposed to AV/digital input. AV input/YUV component handles digital better. No one connects their DVD devices to their TV via RF (either directly to the antenna socket or with a modulator/attenuator) anyway. Because a VCR is mostly analogue, it will work fine with an RF connection, but DVD is digital, and so won't work as well, if at all.

RF also goes through the tuner in a TV, creating cross-interference, whereas AV is a direct input and is separate to the tuner.

I would say an RF modulator would not be designed to handle the output frequency that your DVD device generates. Throw the modulator out, or perhaps get another TV, or use RCA cables instead if the TV has AV inputs. Whichever is cheaper and easier, but don't use RF accessories except a standard antenna if/as required.

How do I connect to Sharp HDTV and Comcast cable


Your dvd recorder only has rca, red white yellow inputs it wont allow you to record in HD, although you can play your comcast box any hd, regular digital through and record. Hook up the comcast box if HD through preferably HDMI if not get one from comcast. The HD box is the only box that allow HDMI, component and regular RCA and some RF out. This way you can play HD to your set but also record through RCA or RF again will not allow for HD record unless its TiVo. Hope this helps

How do you hook up the dvd player to the tv with a vcr hooked up to the tv


Leave the cable box powered on but disconnected from the TV or VCR. All other components should be disconnected and unplugged, giving clear and easy access to all connections. If components sit in an entertainment unit, make sure all A/V cables can reach the RF modulator and the cable from the modulator can easily reach the television.
  • Step 2 Hookup the first coaxial cable from cable box output, usually labeled "TV," "TV out" or "Out to TV" to the cable "In" on the VCR. Connect the second coaxial cable from the VCR's out to "TV" to the coaxial input on the RF Modulator.
  • Step 3 Connect the third coax cable from the coaxial cable "Out" jack on the RF Modulator to the coax cable "Input" on the television.
  • Step 4 Take one A/V cable, connect the red (right audio channel,) white (left audio channel) and yellow (video) from DVD player's "Output," to the corresponding DVD "inputs" on the RF Modulator. Place components as desired but still disconnected from power. Plug in all power cables including the RF Modulator's into the surge protected outlet strip.
  • Step 5 Make sure the Channel select switch usually found on the back of the VCR and the Channel select switch on the RF Modulator are both set to Channel 3. This channel is used on the television to view your components.
  • Step 6 Turn on the power strip and turn on the TV. Cable reception should come on as usual. Set the TV to Channel 3 and turn on the VCR. With VCR on test it by playing a video tape. The RF Modulator should sense the signal and automatically switch to "VCR."
  • Step 7 Switch off the VCR and with the television still on channel 3, turn on the DVD player. As the RF Modulator senses the DVD player signal and switches to DVD, its welcome screen should be seen on the television. Play a DVD to test and once you're done with the DVD turn it off and the cable should come back on.

    Connect magnavox dvd to ge tv HELP!


    You need to go get an RF modulator. They can be purchased at Radio Shack or a number of other electronic shoppes for a reasonable price.

    The RF modulator connects to the coax cable connector and it has inputs for the RCA connectors.

    Cheers ... Best wishes
