Re: Tevion AVR-2006 Home Theater Receiver
Well, further to my last message; it seems that C183 wasn't the only cause of the problem. With the top & bottom off the unit on my table, the unit would work, but only sometimes. So after a couple of months and a marriage breakup, I have finally got back to looking at this problem again.
I have decided to look into the perceived power supply issue again. I still have only +/- 45v DC leaving the bridge rectifier on the power board. Given that the AC input to the bridge rectifier is from a toroidal transformer; when I measure...

Re: Tevion AVR-2006 Home Theater Receiver
I have finally had some time to investigate further. After testing the main board capacitors with an ESR meter, I found several caps to be faulty. The first one I changed, (C183) fixed the problem; it was a SAMXON 470uF, 10v GS series. I now am just going to go through the rest of the 'high ESR caps' and change them.
There are several caps on the power board which are also test as 'faulty' with the ESR meter and it's my intention to change them as well.Leave a comment:

Re: Tevion AVR-2006 Home Theater Receiver
OK; I hooked up speakers to LEFT & RIGHT outputs; there is no audio output, even when the internal tuner is used (as before)....Leave a comment:

Re: Tevion AVR-2006 Home Theater Receiver
Hi; the new 10,000uF 63v Panasonic caps arrived today and I have just soldered them in. The -55v rail now measures -45.2v; the +55v rail now reads +45.1v.
Re the speaker output voltages, they measure as follows:-
LEFT 30mV
RIGHT 14mV
CENTER 30mV
LB/BS 18mV
RB 12mV
RS 11mV
LS 17mV
So, where to now? Do I go looking at the power supply board; checking all capacitors (esr) or is it best to look on the main...Leave a comment:

Re: Tevion AVR-2006 Home Theater Receiver
For the record, I have just had a close inspection and it looks like all caps are SAMXON from three different series (GR, GS & ?)........Leave a comment:

Re: Tevion AVR-2006 Home Theater Receiver
Which is understandable now, given previous message; however , I ordered 63v so I'm stuck with them now........Leave a comment:

Re: Tevion AVR-2006 Home Theater Receiver
One thing I forgot to add to my original post is that video switched through the unit was still perfectly OK, the only issue being audio.
I have ordered Panasonic Caps which should arrive tomorrow....stay tuned...Leave a comment:

Re: Tevion AVR-2006 Home Theater Receiver
All - thanks for the replies....
The 10,000uF capacitors are SAMXON; I haven't looked closely at the others in the unit as yet, but there must easily be around 100 or more in the unit. From my original look at the unit a week or so ago, there are more SAMXON caps as well as other brands.
FYI; I removed both of the 10,000uF caps last night and am going to order replacements today from RS Australia. They were my first choice, even though their ESR and Capacitance values seem OK. Once these are replaced, I'll then...Leave a comment:

Tevion AVR-2006 Home Theater Receiver
Hi,
I'm wondering has anyone got a service manual or schematic for a Tevion AVR-2006 receiver?
My unit seems to function OK, except there is now a complete lack of sound. This problem originally started as an intermittent fault which could be overcome by switching the unit off / on; or by changing to a different input and then back again.
I am going to start looking though all of the capacitors with an ESR meter, so this will take quite a while. There is only one capacitor that obviously needs changing; a 10,000 uF 63v which is located (with another... -

Japlytic; How old is your WAG160N? I have the same unit, a version 1, and I'm curious to know what age it got to before it started playing up?Leave a comment:

Re: New Members - please post your introductions here
Hi all. I happened onto this forum whilst investigating faulty caps in Cisco 857 & 877 routers. I have been involved in electronics through my career in telecommunications and I still get quite thrilled by being able to fix what most other people can't. As I have found fixes for several faulty products that I own; this forum has already proved to be invaluable.
Thanks!!Leave a comment:
