You probably have damaged the power amplifier (TDA7294), which causes a large increase in power and eventually fuse. Pull out the electronics and check them.

Does anyone have a detailed +5 mod for the spring-loaded version and small pre-amp? Please I am in a desperate situation to get this working!

Default Getting lost in this thread and cannot find my answer

Hi to all.

I have trawled through this entire (EXTREMELY HELPFUL) thread and have either overlooked, or simply cannot find a direct answer to a common issue.

I know this has been asked 1000 times in various ways, but most seem to be driven by wanting to bypass the POD completely, which could be an option for me, but as I am already going to buy a standalone receiver and better quality components for our family lounge, the Z-5500 will either go in the bin (a VERY expensive waste which will leave a bad taste in my mouth) or I will try to resurrect them and pass them onto my daughter ... a much better option.

My Z-5500's have only ever been used at TV listening levels (Media Center and Cable TV here in the UK) and everything has been working fine for the 1.5 years we have had them, until the Sub stopped working last week.

I have opened the POD up as well as the subwoofer and looked for any obvious loose connections or bad/dry solder joints etc.

The actual driver works (connected it to the Centre out and ran the pink/white noise test) but the sub output wires are dead ... including trying them on a loose 8Ohm driver.

Is it more common that there is a quirky POD or wiring issue, or are one or some of the (preamp or amplifier itself) components known to die for no reason like this.

Does anyone know the simplest way to test the Sub amp or preamp to determine the fault?

I am quite happy with a soldering iron on small components etc and have a decent multimeter, but am not knowledgeable when it comes to identifying faults (without advice that is).

If it were simply a blown transistor or an op-amp and I could identify this, then I would give the repair a go ... if it ended up being a more complicated fault, then I would have to consider the bin or wasting more money on a repair.

Thanks for any help on this.

Steve

Hi every one, Can anyone assist me with my z-5500 , it kept burning fuses so it was taken to an repair shop where the guys replaced two ics that was faulty TDA 7294. Now it does not burn the fuses instantly but it powers up the pod but now no audio is outputted from any of the speakers. The pod works perfectly because i connected it to a friends system and ot WOrks but the woofer PIDR817 (SPring Clips) refuses to output any audio , all the other ics were checked and seemed to be fine ..have anyone encountered that problem and have a solution ...email me markavelee@hotmail.com thanks

Default z-5500 no audio

Hi,
one more thing i connected headphones to the pod i hear audio from the headphones but non from the unit itself .
Or does anyone have a working sub unit with a PID higher than 700 willing to sell, Im left with a working pod unit and satalite speakers but no subwoofer

There are 2 options. The first is that your control pod does not match the subwoofer electronics revision (check PID). But if before burning fuse set you to work, unfortunately electronics subwoofer is still broken (I have the same problem ).
If you connect headphones to the control pod, the music comes directly from the computer (bypassing the subwoofer electronics).

Well i dont have a descrete amplifier to bypass the subwoofer, even if i did i wouldnt want to do that but rather try and have the electronics in the woofer repaired, but the pod does match the woofer unit, its the original pod and woofer configuration. I know the problem is with the subwoofer's electronics what im asking is how can it be fixed
