DAV-S400 Power Supply Smoke, C916 Value please

[IdRatherBeSkiing]

Hi, My DAV-S400 / HCD-S400, power supply after 8 years has failed. The smell of smoke in the living room was quite bad. Good job the kids had stopped watching Cinderella and had come into the garden. I've tracked the burnt out part to C916 on the PSU. I'd like to replace this capacitor but its quite a specific Capacitance/voltage value and type and there is not enough left to read the numbers off.

If anybody has a PSU to look at, its next to the biggest electrolytic and the large heatsink mounted IC, it would be greatly apreciated.

I've managed to find  service manuals on the web, but the exact part for the exact model is not listed. (I'd be fine if it was a -S500/S800 etc).

*** Caution *** Only take a look if you know what your doing, this is a hot side switch and that large capacitor could be charged up to >250VDC...

Sony if your scanning this maybe you could dig out the Power supply drawing for the HCD-S400 power supply and take note of the smoke comment for future reference?

I'd take a look at new box, but not enough options on BluRay + 5.1 Sound + DLNA (with all features working) at a fair price yet.

Thanks

Sony never encourage home hardware repairs I'm afraid so we wouldn't be able to advise. Whilst you do seemingly know what you are doing, there are liability issues if we recommended a certain part and then something happened post repair.

We would always recommend taking any faulty device to an authorised Sony repair centre, details of which can be found at the top of the page.

Alternatively you might be able to get a BDV-E370 which has just gone end of life at a pretty good rate - fully loaded with all your requirements, plus iPlayer and various other video on demand services...

Thanks

hi , did you get sorted out ? i have the very same problem. it blew the internal glass cartridge fuse and i took the chance of changing it without investigating . nasty results , it blew up a cap beside the large cap and heatsink . i would be very interested to know how you got on. if i can make any progress i will let you know .

Still, looking / asking mates if they had one. Something may turn up, Sounds like C916 for you as well. My plan was to just replace the cap and the fuse (mine has gone too). hoping nothing else has gone, and just down to a tired, 8 year old cap, beyond that I'm not sure its worth the effort. Note***350VDC!!!!***, may not have discharged. did you cap look like this?

[joeconnolly100]

yep mine is just like that and maybe even worse ! it was still sparking hours after i had the psu removed from the machine. it would be nice to think that if this part was replaced we would be back in business but i think it sounds too good to be true. i think a new home cinema system is on the cards but i would still like to persue this as a hobby type fix. ive been lookin at forums online but no help found yet ! thanks for your reply , keep me posted please !!

Same problem  C916 and a blown fuse.  Mine has not totaly disinitigtated and readable, except there is nothing to read. I see no value maked on C916, unless it was stamped on the very top and in very small text.

Fuse see rated at 3.15A, byt slow or fast blow???

If anyone knows the cap value, greatly apreacated.

I must assume Catmando works for or represents Sony.

Liability issue! Never hear about 'deniability clause'.  How about just providing the information regarding what is in your product. Why is C916 omitted on the parts list (yes I did manage to download the service manual), designed obsolescence?

What I see is a company who tries to get customers to buy new or pay high repair costs when the part at fault costs 39 pence! I'm one customer who is not impressed.

Maybe this is a case for freedom of information act

But one thing is for sure: There are an increasing number of people out here starting to feel like they are being held to ransom

mikejamesccott got a photo?

[mikejamesccott · Accepted solution]

Better than a photo, the value 🙂     What Sony do not want you to know-  C916 is a 1500pF  10% tollerance, 2Kv.

I bought a working system on eBay to find the part value, and will sell the system on afterwards. Written on the cap is  BC RR 125K 2KV

You can decifer the code at http://www.electronics-tutorials.ws/capacitor/cap_5.html

BC= disk size >7.5mm

RR= low loss

15=value   2=number of zeros. in pF, so 1500pF

K= 10% tollerance

2Kv  the DC working voltage  SO BEWARE SOMEONE'S PRIOR NOTE OF 350V

and if you want a 100% match

Dia=13.5mm

Lead spacing 5mm

but there's lots of room

NOTE! I saw a comment on another site stating there were 3 values for C916, depending country. I am in the UK.  I have no verification on the 3 values issue, and they did not give the values.

The disclamer: The above is what I found by opening a working DAV-S400.  The info from what I found on the internet. I depart Monday for 12weeks away so cannot get a new cap and fuse (3.15A. but do not know if fast or slow blow) until I return. I will know then if a new cap and fuse fixes the problem.

Hi

I dont know if you are still talking about this power supply subject ?

I have HCD S400 which is about 10 years old. I have hardly ever used it in all the time i have had it.

Hence i keep it in the tv cabinet behind a glass panel. It is all connected and occasionly use for the radio. What a waste as very good system. I last used it, listened to the radio in january and all ok. But here comes the problem i live in spain and yesterday hottest day for a long time. Listening to radio and stops working, oh dear maybe not such a good idea for it to be in the cabinet with little ventilation.

So i left it to cool down, no joy.

I took cover off and found no smell of burning or anything like that on visual inspection all ok.  Checked the small glass fuse and on off switch both working as should be. The only thing i can see is that when it is on normally a red light appears behind the on off switch. This is not working when the power is on.

I was hoping that when i took the cover off i would see a big arrow pointing to a thermal trip switch saying push !

Hoping you might be able to give thoughts as to wether to put into shop for repair or would i be wasting my time.

thanks ochyan
