I have sound but no TV picture. Tape deck works and picture and sound are there when playing a tape

After putting a known good tape in the deck, push play, if the tape doesn't move, try rewind and FF. If nothing happens, the deck has a problem. I assume this is a cassette deck. If so, I always try the thrift stores for a new(used) one. There are good bargains there.

There is either a cam belt that is lose or the flywheel assist can not move the head base due to hardened grease. It needs to be serviced.

Are you sure you have pressed the tape monitor switch or button on the amp or receiver? The Tape Monitor switch is the most common failure in amplifiers and receivers provided the tape deck is hooked into the correct place on the back of the unit. The tape decks outs go to the play in on the amp and the Record outs go to the tape decks inputs.

The Bias control is used during recording. If you turn down the bias, you will get more highs, but the distortion will increase, and then start to increase dramatically if you back off the bias more.

As far as playing tapes from different decks goes.......

1..Does the tape that you recorded on your deck sound OK on your deck ?
2..Does the tape that you recorded on your deck sound OK on other decks ?

If 1 and 2 are true, then your deck is OK.

If the tapes recorded on a specific deck sound bar on yours, but 1 and 2 are true, then the other deck is faulty.

When a deck leaves the factory, the head is aligned to a " standard " tape. By standard tape I mean a very special tape recorded in such a way, that a tech can tell if the head is out of align and "tweek " the physical alignment of the tape head..

All decks are aligned just a little differently, but fairly close to each other.

first do the mechanicals....is the head of your deck spotlessly clean ?. Use 99% pure isopropanol alcohol and a cotton swab. Never use anything metal to clean the tape head. If you scratch the head, its toast.

If your deck is clean, plays its own recordings well, and those recordings play well on other decks, then your deck is not the problem.

Hope this helps,

Sounds like the cassette tape itself is too tight to play, try fast forwarding or rewinding the tape in the deck all the way to the end of tape several times before trying to play. This may solve the problem

check your cables to the units channel that doesn't work, for breaks. Does the cassette player play back a pre-recorded tape okay? if it doesn't there might be a internal fault.
Check the wires to the tape head to see if one is off.

Bypass the reciever. Just mixer to tape deck. You will get a better recording anyways!

If you have any of its sound outputs connected to a TV or tape deck do they get the signal? If so, then we know there is sound processing somewhere inside the unit but not emerging to anyplace that requires amplification.

A quick basic check would be to tune an FM station, run an RCA cable pair from the audio output for a tape deck (see the picture at the link) to an analog audio input on your TV. Select that input on the TV and you shouls hear the FM station, or anything the receiver is configured to play. If it's silent then there is no audio signal circulating in the receiver to get out to the amplifiers.

Check to make sure Multi-Channel input is not selected unless that is what you're listening to as it bypasses all other sources analog and digital EXCEPT the tape; and check any Mute or Zone Controls, too.

If you hear the program on the TV but not through any attached speakers, then the amplifiers are all disabled for some reason. The click I asked about before... when you turn it on does it get a click about 5 seconds later. That would be the protection circuitry turning OFF to allow the amplifiers to function.

I notice it has a Tape function. Make sure it isn't selected as it assumes a tape deck or processor is attached and will only play back what would be coming FROM the tape deck or processor. On my Pioneer receiver it also disables any digital signal processing.

Sometimes when I'm watching TV with the remote on the seat someone moves and something bad happens. It's always some unfamiliar button that gets touched unintentionally. Look over the remote for things like MUTE, Multi-CH, Tape.

It seems to be fixed. I ran a new tape through the machne as suggested. To be sure, I also used a VHS head cleaning cassette.Works fine, now. Thanks

Each unit (the EQ and the Processor) should have left/right in/out rca jacks as well as L/R tape in/outs. The EQ or processor use the receiver's tape loop and then provide a tape loop to replace the one they've used on the receiver.

You plug the first unit (let's say the Sound Processor into your receiver/amp as if it were a tape deck (Processor's outs connect to reciever's tape ins (play) while the Processor's ins connect to the receiver's tape outs (record).

Then you chain the EQ off the Processor in the same way (EQ outs connect to Processor's tape ins (play) and EQ ins connect to the Processor's tape outs (record).

Last you connect the tape deck to the EQ as follows. Tape deck outs connect to EQ's tape ins (play) and the tape deck ins connect to the EQ's outs (record).

This will put both the Sound Processor and the EQ in the receiver's tape loop. In order to have all the receiver's source signals routed through them you may have to engage a Tape Monitor switch or button somwhere on your amp which will route the tape loop to your speakers.
