Hi, this is my first post on this forum. I have a Oppo BDP-105 that I bought second hand back in 2016, I left it on pretty much 90% of the time since 2016 ( 7 years ) . I mainly used it as a DAC , I only spun disc once in a while. Recently I started to notice that the front panel display was more faded than usual, also, at times when I play a disc the player freezes. I decided to open it up to inspect and noticed that there were 3 caps that look like they have leaked. Also, there is a brown colour on the board and on some of the soldering. I'm no electronics expert when it comes to these things but I've contacted Oppo and they haven't been able to give me much info other than telling me to send it in. I paid the service fee and will be sending it in this week. Seeing how I am from Canada , it will cost me around $350-$400 canadian dollars after service fee and shipping.
This brings me to my question, is this the kind of repair that Oppo can do? I mean, if the board is damaged, are they able to simply swap the analog board for a new one? Just trying to see if it is even worth for me to send it in given the damage.... What can you guys make of the pictures attached? Thanks!

Oppo made great CD players, I never got my hands on one, but I bought the Sonica DAC and before long the company stopped making audio components to focus on smartphones.
They promised to continue providing support and technical service so I'm glad they answered you.
The decision is yours, I would send it before it falls into the hands of any adventurer who could make it unusable. Oppo would have to have access to original parts, is what I think.

I don't think it is necessary to change the entire board due to the typical failure that you are describing, capacitors with loss of dielectric. Any technician can solve that, but I also see that those small capacitors that you have indicated could be in poor condition.
The subject is SMD soldering, which is a bath of surfaces that is carried out simultaneously from above and below by immersing the entire board in molten tin, machines do it, obviously, but very few technicians invest in a similar soldering station given its high price, although there are third parties that provide this service to technicians if they bring them the complete boards, it is the same as in the mother boards of computers. The vast majority of technicians do not have the possibility to carry it out properly and end up spoiling everything with their 60 U$S soldering iron that is not exactly "a soldering station" ....
But, maybe someone will offer you a better solution here. Good luck and keep us posted.

Fwiw I don't think there's anything visibly wrong with the large Elna caps. The brown substance at the bottoms is just glue. It can eventually become corrosive and/or conductive, so there's that to consider.
If that Oppo service fee covers any repairs necessary to restore full functionality (and includes shipping), I'd say that's not a bad deal.

Is just glue ?
Was the glue applied to the top of the capacitor? It is leaking, it is evident, it is also visible at the base, it does not have the typical thickness of the glue, in addition, this technique of gluing the electrolytes is older than when that Oppo was manufactured. Are you a technician ? 😒

I'm no expert , nowhere near most of you here but to me that doesn't look like glue if I base myself on a picture of the actual analog board :
You may be right, also I don't see SMD welds on that board.
Maybe I was rushing the comment, but the OP ( you ) was desperate for an answer..... 😊
Hey, and that smaller capacitor, next to it with the swollen cross, that one is about to burst!!!!😡

Elna caps look like that. It's not about to burst.
FWIW, in the pics above i see glue, solder flux and reflections. You can see the glue in the promo pic above, on the board, just above the 2 main caps.
Yup. The U1 and U14 are voltage regulators and the brown stuff here is leftover flux. Not to worry. And the brown stuff around the large caps could indeed be glue. If the darn thing works, I say: keep playing and don't worry. 🙂
Good luck.

What is the display type?
Vacuum, LED, LCD?
Elna are reputed, so is Oppo, unlikely to be fakes.
Just switch off the unit when not in use, unless you are an insomniac.
Everything has a life, do not waste it.
Get a meter, and check the voltages, it could be a leaky resistor or whatever, cause of fading display.
Or simply that it is end of life.
Replacement will be more expensive than a new Blu-Ray player. Don't bother.
Freezing?
Check with another disc, if it is happening, I would take a close look at the power supply board, looking for the obvious things like cpacitors and loose contacts.
Then go deeper.
SMD work stations start at $15 here, the cell phone techs all have one.
No big deal repairing SMD boards here.
The issue may be finding SMD parts, regular ones will work,space permitting.
Find the schematic first, if possible.

Are you sure that those marks are not on purpose so that they open on their own before this happens ? 😱

Capacitor Elna, pass the magnifying glass over it.......

That's the standard Elna stamp pattern. Nichicon have a cross, Rubicon a Y etc etc.
There are sites for capacitor identification, the top patterns are distinctive, and are hard to duplicate.
That top pattern and the bottom plastic / rubber molding (at the leads) is a good way to tell genuine from fake, the sleeve can be copied very easily.
Yes, the function is as vent, sometimes the cap opens at bottom and becomes a projectile.
It has not happened here.
Glue is used to keep parts in place during wave soldering, so less labor is involved. Again, no surprise.
@academia50, please describe the system you use for listening to music, you seem to be very particular in your tastes.

If your predominantly using the BDP-105 as a DAC, spend that $400 on a dedicated modern dac that will outperform the ESS chip in the Oppo.

There are threads here about using Linux based computers for storing and playing music, and programs for use on those.
And a current thread here has some information for people who prefer Windows as the OS.
C$400 + service + shipping = C$650 or so, enough to buy a new unit, whichever you choose.

Here it is, I don't see anything special in my tastes, I just try to make good "pairings" guided by my audio experience of so many years.
Prima Luna Dialogue Two-Tubes:Kt-88 Sovtek-Shuguang EL34-JJ Electronics,
Micro Seiki DQ-43-Denon DL-103 MC-Ortofón 2M Red MM, Project Tube Box S2, Oppo Sonica DAC, Philco DVP 500,Bheringer NX3000D - Speakers Troels Gravesen DTQWT II (Diy) Subwoofers Eminence DeltaPro18A 2x18" (Diy)
The previous one is my main system, I have others that I like a lot too, they are used and combined continuously. Some remain unused on the top floor of my house during the summer, like now, very hot and I don't like to use air conditioning...
Turntable CEC with Ortofon 2MRed ( too, good cartridge for the price) ) JBL LE14C ( Diy) Nad 3020 ) and PC server music (Diy)
Amplifier RCA 2x75 Watts Rms (Diy) , or Sansui AU4900, Speakers Technics SB1950, Smartphones, etc, etc
Oh, I forget, amplifier Phillips 2x25 Watts ( Diy) , Amplifier subwoofer´s Dayton SPA250 ......
Why do you ask, I'm curious..... 🤔

Whatever the drawing, if they are inflated, they will burst at the weakest part.
