    Question yamaha rx-v559dab amp/reciever seems to have developed a problem, can anyone help ?

    Hi again people,

    My yamaha rx-v559DAB amp/receiver (uk model) maybe seems to have developed a problem, can anyone help ?

    I bought this amp/receiver (yamaha rx-v559dab) brand new maybe about approx 5-6 years ago and its been working great ever since and used for several hours daily but I really only use it for the DAB radio/optical sound from my computer to the amp and then it gives amazing quality sound to my sennheiser headphones, that's about it, yes I know its a bit of a waste of money as it can do so much else etc but that's not in question, , I am just used to the darn thing now and as I say, the sound quality is amazing, would hate to have to part with it really, but if needs must then I guess I will have to.

    I have always just switched it on and off to standby using the remote every night and never off at the plug etc, only onto standby, as I say, its always been fine.

    So, the past week I started to notice that it wouldn't switch on with the remote, tried the on/off master button etc on the Amp too and that usually doesn't work either, sometimes it might sometimes not.

    So today it wouldn't go on again and I popped the fuse out the plug and put a new fuse in, plugged it back in and hey presto ! it worked, BUT, then I thought ok lets try the old fuse that I thought might have blown in the first place, I put the old fuse back in the plug, plugged it back in and boom hey presto worked again, so its not blowing a fuse, its something else.

    I don't have a clue what it is that could be causing this and that's why I come and ask for hopefully someone that will know the answer please ?

    Right now I have it on and its fine and I was thinking about just leaving it on 24/7 but just turning the volume right down, but I am scared to do that as going by the online manuals I have found it is supposed to use quite a lot of electricity, I don't know if they mean under full load or what, again I have no idea, but if it was going to use a lot of electricity I couldn't leave it on when not required, know what I mean ?

    Ok, I hope someone might know whats going on here and might be able to offer some assistance, its appericated

    ok, that was early on today I was meant to have posted that, since then though I have done this >>>

    Since earlier and In the meantime I went ahead a left the amp on all day and tonight too and its still on, bit scared to turn it off really as that's when I get a problem trying to put it back on (see message above this one for details).

    But......although I have left it on as I said and with the volume turned down to zero, does this mean the machine will still use the same amount of electricity that it would use if the volume was turned up ?

    I found a copy of the manual for the machine online and can see that it says the machine uses 360watts of electricity, I know that's a lot as my plasma tv uses a bit more than that amount too and that is expensive to run, but I don't know if they mean that's under full load E.G- volume turned up full, or if that means it will use 360watts nomatter whether the volume is set at zero or up full, I know that on standby mode it only uses 0.5watt or less, but again, the problem I am having is making me not want to put it on standby or anything, again see the post above and you will know what I am talking about thanks.

    Put it this way, if I cant get this fixed myself and I had to take it to a specialist electronics place and they were going to have to charge me something like maybe ?100 for fixing it then I would rather just bin it and buy a new amp, know what I mean guys ?

    If anyone out there can help me, please give me a shout as I don't know if I can afford to have this thing switched on 24/7, but I don't even know the answer to that question either like I said , got the wife moaning at me about it now (the electricity it "might" be guzzling) and everything though, the usual, .

    ok, looks like I have found the answer to one of my questions which I thought myself was a bit obvious common sense anyway, but I still had to find out and here's the answer I found regarding electricity used with volume set at zero >>>

    "Two Examples of Exaggeration I have Seen
    1.JVC “520 watt” bookshelf stereo system. The average power consumption at half volume was 52 watts. 520 watts is a peak rating which you can’t actually get from it. Most stereos have this unrealistic label on them, and it is in bold to get your attention. It is a highly successful gimmick. The power consumption printed on the back is 245 watts, but, that is the maximum, and at volumes which you shouldn’t listen to it at.
    2.Klip Extreme 40 watt speaker system. The average power consumption is 13 watts, and, due to other physics laws, the power I get out of it has to be less than the power consumption rating.

    You can definitely expect your home stereo system to use less than 100 watts, unless it is an unusually terrible design, or unless you play it very loudly."
    ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

    But this still leaves me hoping to get the answer to my "main" question, I just cant find an answer to that at all, hmmmm ?

    Don't do numbers, 360 watts guess on full power.

    if it still works and popped fuse, intresting


    OFF TOPIC:-

    Was given a tv once, gave straight to my fat unemployed fruend, fuse in plug blown.

    he put 13 amp in abs watched fir smoke.

    small capacitor across the mains dead sshirt. (iShit Failiure) cut it off abd watched happily ever after

    aye strange, I first thought it was blowing the fuse in the plug cause each time (couple of times) I swapped the mains plug fuse for the amp and then it worked, so I thought "problem defo in the amp causing it to blow fuse", so then I tried again but this time putting a new fuse in plug, plugged it back in wall, worked fine, unplugged it, put the old fuse that I though had blown back in the plug and no it hadn't blown at all, it also worked, YES SO DEFO IS NOT BLOWING A FUSE, as explained in detail in my first and second post.

    Still haven't switched it off to standy though when not in use, just left it on and volume down until I try and get some advice on this, that's the aim of the question obviously

    Called a couple of electronics shops up but they gave me the usual garbage like "ohh bring it down and we will test it out for a day or two", usual stuff with them and then you go back and say ye it needs a new this that and the next thing and that would cost ?150 to repair.............I mean, yes it still at the grand old age of 5 years old may be a bit old, but these things are expensive man, just try and buy a second hand one or even new one if you can get one online and you will soon see, think it cost me about ?400 back 5 years ago man, , true.

    p.s
    I canny keep going on with leaving it on 24/7, not only will that be putting a lot of strain on the whole workings of the machine even though the volume is at zero, its not just that, it will still be using some electricity man, burning money so to speak.

    Ok chaps,

    I don't know if much peeps are looking at my posts or what, but I just wanted to add now that after leaving the amp switched on but with volume down as low as it can go (zero) to save electricity, its been left on for maybe 4 days straight days 24/7 just like that now and I have been using it that way without putting it onto standby as that is when the problem stated in posts above occurs.

    Anyways, so last night I thought I would be brave enough to try a different tactic and that was to switch it off using the main master on/off button on the front face of the amp as its easy accessible for that.

    So I switched it off like that and then instantly tried to switch it back on the same way but had the exact same problem as stated before as in that it wouldn't come back on, no lights, no nothing !

    So as it was time for bed anyway, I just left it switched off with the master on/off button switch at the front like I said and left it like that overnight, got back up today and hoped to be lucky and hey presto !!! I pressed the master on/off button to the on position and was happy to see that it switched back on and saved me having to get on the floor and mess about with the plug/fuse etc when they don't even blow anyway.

    Ok, still following me ? I bet not, .

    So, with all that I have said so far, whats going on man, anyone know ??

    I thought possibly that with switching it off at the master button and leaving it for hours like that it somehow cleared the memory or something, but If that was fully the case then it wouldn't have remembered things like the radio settings and volume/base/treble levels etc and it has remembered all that, so that seems strange to me, how about you ?

    Also, the remote control works fine but as previously stated, if I use the remote to put the amp onto standby mode then it wont come back on, its strange man.....then also if I leave it off at the master button for maybe 5 minutes it then wont come back on again either, but it seemed to with leaving it for approx 8 hours or so, hmmmmm, I don't know, anyone got any ideas ???

    Cheers .

    As JoK says bad cap usually on smaller psu inside near transformer. Powers the remote as well. Cant find diagram but a lot of models have same problem on c4 cap not sure if yours is exact same. Other than that maybe bad solder joints or relay? hth

    Well, I have just had to keep unplugging it and then plugging it back in again and so far that is working and I guess it could be worse, touch wood it doesn't get worse, , still not right though and you guys are probably correct in what you said too, but end of day, I think I should just continue do what I am doing until it gives right up totally rather than even thinking about cap's etc, don't youz ?

    Cool

    When I opened it up the TV there was 6 or 8 caps on the power board, there was a few visible that were damaged but I changed the lot for less than ?2-3.

    Get it open and yer solder iron out

    JoK
    Yea man, I know JoK, BUT, that's where the problem starts, hahahahaha, last time I tried replacing a cap was in my VU box and mannnnnnnn wow !!!, I bought a good solder iron, magnifying glass etc etc and knew exactly what needed changed and I went ahead and attempted it shaking like a leaf, few cans of beer later back to it again still not shake free, , I slightly managed the job but it was obviously not done correctly and for that reason I have a very well known friend on DK here that came to help me out with sending the box to him etc and that way it got sorted and that was that thanks to him

    BUT, with an big AMP/receiver like this one it weighs a ton man, would cost me a total fortune to send it anywhere, so that's a no-no and I know those electronic shops are rip off merchants, so I might well be launching it as you say @JoK, , I dunno man, just need to see what happens I guess and yes, no doubt it will get worse like you say, only thing I can say about that is that at least I will still be able to listen to the sounds via the computer, not as good quality sound, but still, better than nuffin man.

    I will just need to see how it goes, if worse comes to worse I maybe drop it into a wee private electronics shop and get an idea of price, but as I said, they are usually total rip off merchants for things that cost pennies and take them only a few minutes to do etc.

    But yes man, thanks JoK, I know what ye mean mate, just wish my drunk shaky hands were as solid as they were maybe just 15 years ago, LOL.

    Salty,just take note of the caps when you take them out,especially with power circuits like amplifiers,that you actually put the caps the right way back in,ie,look for the ---- on one side of them.THEY ARE POLARISED !!!!.They only go one way back in.They were more than likely through hole components,so would have a print on the circuit board telling you this.

    As Jok says,straight forward enough.....

    Best of luck mate
