Hello!
Sorry to admit, but your VCR's signal processor is down. On screen display is generated by microprocessor, but video signal by different circuitry. Anyway, there is nothing you can do, except surrender to repair shop. Or, worst case scenario: buy another one. Even though I won't recommend to do so. "Modern" VCRs are cheap plastic toys, won't last too long, no replacement parts available, etc. If you have some technician's background, you may open the unit and look for "bloated" capacitors in power supply area or check electrolytic capacitors with "in circuit" capacitor checked, if you have one. If not: try to look for reputable repair shop, what stays in business for a while. there, still might be the people, familiar with VCR problems.
good luck with your project,
thanks,
Alex.

The heads are inside the VCR. You can buy from your Local dealer a VHS head cleaning cassette that should solve the problem. Normally I would recommend going inside the VCR to clean it with Servisol Video 40, but in your case I would stick to the tape!

SOURCE: I took out some 2001 9/11 taped back then.

You can purchase a VCR cleaning tape that will do the job. However the best way is to buy a can of Servisol Video 40 (small one will do and it will last a long time) then remove the top cover of the VCR. Spray the VCR heads. Shinny Silver things and any moving parts that the tape touches. If your not certain what to clean, with the cover off insert a tape and press play. Remove the tape and spray small amounts on the surfaces. If you can see a lot of dust you can wipe the heads etc with a cotton bud. A VCR housed in a smokers house will need extra work to get it clean. Once dry you can test a tape. If you see flecks or spots the VCR will need further cleaning.

I have a Syvania SSD803 DVD/VCR combo that I connected to my Panasonic Smart TV. DVDs play well with video and and audio but I only get black and white video. How can fix this issue?

There are a few possible reasons why you may be experiencing black and white video when playing DVDs on your Syvania SSD803 DVD/VCR combo. Here are a few things you can try to troubleshoot the problem:
  1. Check the video settings on your TV. Make sure that the TV is set to display color and that the correct video input is selected.
  2. Check the cables. Make sure that the cables connecting the DVD/VCR combo to the TV are securely plugged in and that they are in good condition. If the cables are damaged or loose, they may cause the video to be distorted or not display at all.
  3. Check the DVD/VCR combo. Make sure that the DVD/VCR combo is set to output color video and that all of the connections are secure. If the DVD/VCR combo is not set to output color video or if the connections are loose, it may cause the video to be displayed in black and white.
  4. Check the DVD. Make sure that the DVD itself is in good condition and that it is compatible with the DVD/VCR combo. If the DVD is damaged or is not compatible with the DVD/VCR combo, it may cause the video to be displayed in black and white.
If none of these troubleshooting steps resolve the issue, it is possible that there is a problem with the DVD/VCR combo itself. In this case, you may need to have it repaired or replaced

How do I connect a VCR with the TV

Hello,

connecting the VCR to a TV is not a big deal. There are two methods by which you can connect the VCR to our TV.

1. You can use a RF cord.
2. You can use a RCA cord.

I would suggest you use the RCA cord because the RCA connection has a better sound and display quality than the RF. So I would direct you on how to use the RCA connection method.

Here is a picture of what the RCA cord looks like for quick identification;

elect_comp_1.jpg

As you can see from the above picture that there are three cords. The Yellow cord is for display (video), while the with and red is for sound (audio Left & Right).

Turn of the VCR and the TV.

Look at the back of the VCR, connect the yellow to 'video out' and the white and red to 'audio out'. Note that the VCR might have only one audio out, that doesn't matter, just connect any of the red and white.

Now connect the other end of the cord to the back of the TV this way; Yellow will go to 'Video in' while the red & white will go to 'Audio in'.

Turn on the TV and VCR.

Select the TV to Source/AV and the display of the VCR should appear on the TV. Or better still, you can insert a cassette into the VCR, press play before selecting Source/AV on the TV.

By now the connection should be Okay.

If you any more questions or clarifications, please let me know as I would be glad to respond.....

Yours sincerely.

I have a mitsubishi black dimond vcr id like to tune into a sharp tv how do i do this please

Ok, to hook it up to use as a Receiver, and TV, as a "Monitor". Using the antenna cable, plug this into the antenna IN socket on VCR. Now connect up, AV, using the Yellow, Video, Audio, is Red & White, on BOTH TV & Video. Now select an EXTERNAL INPUT on the TV. Now You Tune, and scan for "Channels" using the VCR. Find each channel, and save, now, you use the VCR remote to change channels, and the TV, is used as a "Display Monitor".
The Other way, is to just use the VCR as a "Recorder only, you plug the antenna, into the TV, now at rear of TV, you have a Video OUT, Yellow, and Stereo, Audio OUT, Red & White. Connect up the VCR to the TV using them. Now anything you View on TV, will be out put to the VCR, when you wish to record, simply press record, on Remote/VCR as desired. and it will record.

Panasonic NV-SJ205 Changing Rf ?

ok. This is a really easy one.
All you have to do is hold down the menu button on the remote control for more than 5 seconds, If that doesnt work hold down the power button on the remote control for more than 5 seconds. If that doesnt work hold down the power button on the actual vcr unit for 15 seconds. The first method should work for Panasonic's fine.
This will then display your current rf output.
You can then change the output by using the up and down arrows or the channel up and down button on your remote or the vcr unit.
Press menu button to save or the same button you used to bring up the rf opposition eg power button on remote or the unit.

all the best. Top tech

Panasonic NV-J45

Has VCR to TV hookup been changed? Cabling errors will result in no display from the VCR (no tape video/audio, no menu display). If you are using the TV aux/VCR input connections, you must select this input before anything from the VCR will be displayed. If you've verified hookup is correct, then perhaps something is afoul with the VCR. Try hooking it up to another TV.

How to record from KS 4110 DVD payer to VCR

Connect your DVD player to your VCR ( the out put from the dvd player is connected to the input of the vcr) then connect your vcr to the tv( the output from the vcr is connected to the tv)

Set your tv to what ever channel you connected your vcr to and hit the tv/vcr button on your vcr remote until you get the vcr displayed on the tv.(ensure your vcr is on when doing that)

First, have you doublechecked the video hookup? It sounds like you are using the video/audio inputs to the TV, so make sure you have VCR video out cabled to TV video input, and the TV source/input selection set to that input (video 1 etc.). If this checks out, check for a dirty video head on the VCR, though a dirty head usually results in a blank or blue video display (older VCRs, snow). You could do a process of elimination by hooking VCR to a different TV and see what is displayed then. Lastly, I assume you've tried multiple tapes, just in case a home recorded tape was incorrectly recorded?

DVD/VCR combo player won't work

I had a similar problem and corrected it with a solution found on another site. Try hitting the I/P button on the remote which controls whether "Interlaced" or "Progressive Scan" is used to display the image on the TV. Mine worked when "Interlaced" was used. but no picture was displayed when "Progressive Scan" was used. The I/P button toggles between the two settings.
