Question about JVC TH-A35 System

1 Answer

Radio Tuner problems

After a power fail, my home cinema TH-A35, keeps working, but something is wrong:

When I switch on unit, it always wakes up on radio tuner, no matter what function it was when switched off.
It shows on display "FM 00.0" and I cannot tune any station (it doesn't start finding frequencies.

Also, when I change speakers volume (rear speakers, center speakers and subwoofer), if I switch unit off, when switching it back on, it lost my speakers volume change.

All the rest seems to function normally. I guess it can be a software problem.

Any clue what could be wrong? How can I performe a reset? I mean a default factory reset?

Thanks

Backup memory battery may be the cause.

SOURCE: System unresponsive when modes are switched

Arnt they seperate things? ive seen some systems that dont function if thery are not in that mode. If its in DVD mode nothing on the DVD works, if its in the radio mode maybe the power changes over to the tunner only? you cant play both at once maybe their idea. Will things work when its in the cd mode? Is the unit staying cool?

SOURCE: SUBWOOFER WON'T POWER ON (Grounding out???)

Check your cable that runs between the main unit and sub for bent pins. If they look fine there may be a short in the sub itself that is causing it to go in to shutdown.

SOURCE: PSU problem

The most likely problem is something dragging down the power. There could be a problem within the power supply as well. This is a "switch mode" power supply. That means that if the primary side does not oscillate correctly, you will get this cycling as well. These are hard to diagnose remotely. Typical power problems such as this run about $15 or so for parts plus the local labor rate if it is within the power supply. The parts cost will rise to the $30-$50 range if the output amp section is the problem.

The DVD player seems to immediately attempt DVD mode upon powering on, despite no disc being present. The display shows "ERROR, PRESS POWER OFF/ON TO RESTART" and no other action is possible...


You have an internal mechanical switch/sensor which failed and will need replacement.The reason it is giving this message because the sensor might have been stuck in a position when it was damaged. And also along with it some parts(semiconductors and capacitors needs to replaced too)need some checking too.

Marantz SR870 tuner not working


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.

Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.

NO SOUND From JVC TH-S5 Home cinema system


I know this is an old topic however someone somewhere might benefit from this feedback. I purchased the JVC TH-S5 service manuals from ManualsParadise.com and after metering all the supplies as 'OK', I then focused in on the 'common' lines associated with the two onboard power amps IC's (STK413-400) and found that they were missing a bias supply. This is derived from the onboard 40v Supply 'dropped' down by a 47 ohm resistor R2702 (rated 1/4 watt but advised to make this at least 1/2 watt). The resistor was found to be open circuit i.e. a very high ohmic value. Looking at the circuit diagram again, I would feel that this is going to be a common issue with this unit.

You can't get 5.1 sound from a MP3 source !!! You get a 5.1 sound only from a good STEREO (analog) source or from a REAL 5.1 DVD audio track. Also check your "Autosurrond" setting on the remote-control.

System unresponsive when modes are switched


Sounds like there may be a glitch in the microprocesor. Make sure when you unplug it that you leave it along for a few days and is there any type of clock or standby batterys in it take them out as well. If that dosent correct the problem your gonna need a service manual to trace the switch pulse to see if the units Switch matrix lines are low or lost because of a faulty micro or a bad componet like a small caps they install on the matrix to keep noise off them. Hard one to call with out seeing unit and analizing unit Good Luck
