Marantz ST7001 Tuner - "Internal" Switch won't work
Bought a used Marantz tuner. Works great, but the remote won't work.
Once I flick the remote control switch to "internal" as it's supposed to be, the tuner won't turn on. The red standby light doesn't show, either. I can hear a "click" from the inside of the unit when I flick the switch to "external", and then the tuner works fine (but no remote control, of course, since that's what the switch is for).
Any ideas?

Is the "Play/Edit" switch set to "Play?" That could be the culprit, but since you said you have used the tuner while the 1/4" jack is connected, I assume you are already aware of this possible solution.
If the Play/Edit switch is in the proper position, yet the tuner only works when the 1/4" jack is connected, then I'm led to believe the issue is an internal one with the preamp's tuner switch or maybe the power switch that's activated when the 1/4" jack is connected. I have reached this conclusion because the tuner is obviously getting power when the 1/4" jack is connected, so power itself isn't an issue; getting the power to the tuner when no 1/4" is connected is the issue, and that means there a bad switch or relay somewhere in the Aura itself.
Contact the manufacturer. Fortunately, I use the pedal version of the Aura on a daily basis and have had to contact Fishman for tech support in the past, and they're really great about it. So get in touch with them and explain the issue; I'm sure they can help.
Your set requires a qualified service technician to repair it. Sears repairs all major brands, regardless of where you purchased it. There are also many other repair facilities in your local area:
Hello,
You can use some speaker wire. and pull it apart until each leg is 2 1/2' long and then connect it to the balanced antenna input. Or you can run that 2 1/2' (each leg) of wire to the the coax connecting one side to the shield and one side to the center core of a 75 Ohm coax and then run the coax to the FM input on your reciever. The (two) [2 1/2'] legs create a dipole and the coax prevents high SWR and improves recieve. Remember it will work best the higher you get it.

If you are using the TV in UK, and you are using the internal digital tuner (aerial cable to TV), then the TV may be defective (faulty tuner or audio circuit). In that case call Grundig at the number listed on manual. If TV is using an external digi box (eg. freeview), then check connection from box to TV, test using a different connection cable. Test using a DVD, if TV works on DVD replace the digi box.
If you are trying to use the TV outside UK, and you are using the internal digital tuner, then there may be a problem with signal. In that case purchase a tuner box and connect it to the TV.
Hello,
Make sure your FM antena connection is good. A receiver will not pick up an FM signal without an antena. Even a small piece of wire will work to test. If the Tuner section is bad, an external tuner can always be connected to an Aux input. Due to cost, it may not be cost effective to repair this unit.
Hope this helps.
a digital tuner has one advantage only,the stations can be pre -set.
a digital reciever uses a pll synsethizer to generate a signal to lock on the station,an analog tuner is subject to more drift,and as well the sensitivity is a hair less,but if you get a tuner with fet front end transistors,it will sound better.
alot of people say that the hysterisis signal is more evident on a digital tuner.
buy an old marantz or pioneer from the 70s.
the marantz 2275 is 75 watts a side and will outdo todays 500 watt home theatre amps.
they do not build them like that anymore.
Your unit's micro IC, is in need of a reset.Un-plug the unit and locate the semi large yellow capactor on the main board. (r-h side facing front) Now flip the unit over and look thru the vent holes in that same area and locate the two solder pins. Short them out with a thin metal object, like a straightened out paper clip or wire, and turn it over (just discharge the cap and remove your wire) this will default all settings and restore normal operation.
That works great except I can get the tuner to program any channels above channel47. Is this a limitation of this older model TV
yes there is limitation in old tv.
is there some setting I can change in order to get more channels using the tv tuner?
in INDIA what we do is put a remote control ckt which gives us about 250 channels.
of course we replace tuner also called hyper tuner along with remote ckt or replace whole kit which are cheaply available.& serves the purpose.
hope this will help
