Here are the types of connection to help you see the difference between them, if you can compare them to what you have then we can clarify exactly what connection(s) your using:-
This is a Male coax plug (on the left) and an F connector (on the right) side by side; http://www.zaktronic...20connector.jpg
changed the link on this as the previous wasn't showing, click on expand on the image box for this to see it more clearly.
Now if you have pre made leads that come with the units, you will almost certainly have a Male coax plug (on the left) to a Female coax plug) on the right), and as such you should be able to plug them into each other, hopefully this will give you a better understanding of which plug have\need; http://cgi.ebay.co.u...=item5d287359a8
This is the best pic I could find of the rear of a VCR, it's not your one, but should be very similar, look closely at the aerial in\out sockets on it, as per the lead one is male (on the right marled loop out in this case), the other female (on left marked antenna in on this unit), hopefully as you follow through this it will help to see how these things work together; http://www.idtv.co.u.../DSCF0455Hi.JPG
I notice you have a similar thread on another forum, and they are in the same boat as I am currently, but so you know, where they questioned the need\use of the 3 coloured connections on the diagram i did to try and show the way to go, the reason for this type of connection is it gives a higher quality signal, and the more up to date the units being used, the better connection options there are, so as a guide here is my view of quality of connection going from worst (but still quite usable and is the traditional connection) to the best:-
Coax, then RCA (as per these 3 connectors) followed by Scart, and at the top of the list is HDMI, don't worry about understanding these, it's purely an FYI.
The VCR is definitely the weak link here, so either it's not connected properly, it has a menu option that needs changing, or has some sort of fault, but after going through the manual again looking deeper I have come across the following to do with tuning, but I am concerned about confusing you even more, because I don't have the items in front of me even I am finding the following hard to understand, but take it 1 step at a time and fingers crossed it helps, or at least you can understand this, the following is straight from the manual:-
Set VCR channel
To view playback of a recorded tape, or to watch a program
selected by the VCR's channel selector, the TV must be set to
channel 3 or 4 (video channel) when a TV is connected with
the 75 ohm coaxial cable only.
1. Press and hold POWER on the unit for 3 seconds in
standby mode. The video channel will start to flash in the
Press CH –/+ to set the video
channel 3 or 4.
2. Press ENTER to set the
selected video channel in step 1 into the memory.
3. Turn ON the TV and set to CH 3
or 4 to correspond with the
channel selected in step 1.
4. Turn on the VCR and select any
channel to receive a TV station
in your area. The channel
number will appear on the screen and display for about
Now the specification says the VCR comes ready set to channel 3, I have also looked deeper in the set top box manual, and it's not as clearly stated, but if i am right it is also pre set to use channel 3 as it's output, now if both the VCR AND the set top box are out outing on the same frequency (a possible issue I noted earlier in the thread) then this could well be the problem, so I suggest tuning in one or the other of these devices.
The above is for the VCR, now my gut says it will be easier for you to tune in the set top box, because if you change the VCR then you will have to change the TV as well, so my best advice is do the set top box by using the instructions as follows taken from the manual:-
To set the output channel.
1. Press Menu. The SETUP menu appears.
2. Press ▲ (up) or ▼ (down) to select Output Channel, then press ► (right) or Select.
3. Press ▲ (up) or ▼ (down) to select channel 4 (this is probably already on channel 3, so change this to channel 4), then press Select
I strongly suspect after looking at both manuals this is what is causing the interference between the 2 units, the set top box is wiping out the VCR signal, hence no picture when connected. so I really hope you are able to follow this, but don't be afraid to ask for more clarification if you need it, if you can't be sure you did something right\wrong then we could be chasing our tails until the end of time lol, so as with all this, take 1 step at a time, trying to take it all in can be overwhelming, so literally don't worry if you don't understand (although I will happily do all I can to aid your understanding), because until you slowly look at everything the way I have laid out here, it wont make complete sense until you complete this, then hopefully the whole thing will begin to make sense, hope this helps.
