Im having the same issue with my V1. I noticed there are some voltage written on black thin plastic label around it. and suddenly that come apart and they look like two batteries.

I tried to remove the soldering that was holding the clip and I ended up getting the whole clip off the board.

 

Anyone has an idea how to remove the clip from the battery and which kind of battery will fit here? they dont seem to have anything written on it apart from some voltage and amperage on the plastic label.

is it two batteries or the lower one is is the actual battery and the top part is a holder that got rusted on it and made them too stuck together?

Based on the markings on the plastic 0.22uf 5.5V ina Google search it is not a battery but a super- / backup capacitor.

It seems to be widely available and at a fair price

Very interesting if replacing it actually solves the problem. The on you have seems fairly corroded indeed

Btw do you see any corrosion on other components arround this capacitor on the board?
Hopefully it did not damage other things than itself

I still have to take the video engine board out to see if there is corrosion, from the top it looks fine.

I found the capacitor on ebay, https://www.ebay.ie/itm/292412377560 just €8.

I will update you guys if that fixes it. Thanks for all the help!

Nice. Looking forward to your findings. Would be great if replacing this could make these great TV’sluve a little longer

I had that component replaced and it still doesn't turn on.

Ive been studying thelink and it could be that the IR Receiver & Room Awareness" ( 58Module 8007282 PCB58) need to be replaced. My light turns green for a while which they say on the manual the TV is ready to be used.

Like it doesn't react to my remote at all and I tried other B&O remotes I have working on other tvs and it doesn't turn on. I've been looking for that module part online and so far no luck. I wonder if the cable that connects to it might be damaged (photo) anyone know what kind/name this cable is?

Too bad that did not work, although it might have need to be replaced anyway based on the condition it was in.

Interesting. There are other B&O products where IR problems are related to failing capacitor. Maybe there are capacitors on PCB58 that need to be replaced. Could yo try to take this PCB out and take some photos of it?

You could also try this thing mentioned in the service manual to confirm whether it is PCB 58

Thanks @Madakp for the help.

So I connected the ethernet cable to it and I was able to turn it on via the b&o app, but there is no picture, I managed to play the radio and it works fine but all I see is black screen. And it still doesn’t respond to the remote.

Would this issue be on the T-CON board or video engine board ?( even tho it is functioning without image) and the remote not working can be a related or a side effect from the video engine as the IR sensor is attached to it?

I took some close ups of the boards. the back light one seems like there is some leaking around some parts (brown one and the big black piece) I noticed it today.

I havent checked voltages yet, I need to learn how to do that.

Also on the room awareness module, there a dark spot on the side of a white thing, is that an indicator  that it was blown or something?
