2 How do you replace the motherboard?
how do you replace the motherboard?
mine is XBR-49X900E - what motherboard does it need and how hard would it be for me to replace it myself? Where did you obtain it?
Purchased Nov. 2019. I don't think I will ever buy another Sony after this experience.
Update (10/04/24)
This television, bought in around November 2017, has since at least 2019 or 2020 had problems spontaneously rebooting. It would frequently say something about how the memory was about to be full, (maybe to do with apps).
I put up with that for a long time but in the past week it got to where it would get stuck on the Sony logo during one of its reboots, I think, but I solved that problem by doing a factory reset. It was behaving better than ever before for a few hours after the factory reset.
However I then turned the TV off for the night and the next day when I tried to turn it back on, it would not turn back on.
I started thinking about how I don't want my login apps to be accessed by somebody else if I get rid of the TV (is there a Sony recycle program?) and by any chance it starts spontaneously rebooting again,
so I wanted to erase/reset it again but now it either won't turn on at all or whenever I now attempt to factory reset it again, it is only a blank screen with a green light.
And it does not respond to any kind of push on the power button of the remote or the TV to shut the green light off and I have to unplug it. And it will not do the factory reset now or finish booting up. Blank screen.
To hear your description it seems like it needs the motherboard replaced. But that would be bad if it was not just the motherboard needed.
What does it cost to get the part new? $400? What is an example of a place one could get it? A problem is that this might not be all that's wrong I guess.
I doubt I would buy another Sony after experiencing this. I'm not sure it's worth salvaging. I was told by the Sony authorized service center a 3 hours drive from me that I'm not going to be able to factory reset it if it won't get up booted up
So I should "take a hammer to it" if I'm worried about people accessing the apps that I'm logged into and then maybe I will just go and get a new TV with more space for apps instead of one constantly complaining about filling up its memory
I don't know what kind of TV to get next but I have wanted to have a high-quality TV. The most reliable TV I've had before was a Samsung.
This Sony reminds me of Boeing, like something that I expected to be reliable but isn't.

I used shopjimmy.com for my parts. Type in your tv make and model and it should show you what they have available for purchase for parts for your tv.

@maryp22075 it really is not difficult. The toughest part will be to take the back cover off :-) If you know how to use a screwdriver and how to disconnect a few ribbon cable connectors, you got this mastered. The part number for the main board for a XBR-49X900E a is A-2170-502-A Not sure why Sony makes it so complicated but they call those boards BMKS board. Those are readily available at many online shops. Be aware, they are not cheap when you purchase it new. Even a good used one should work well for you. Before replacing the main board, let us know what the issues with your TV are.

@maryp22075 it has come to a point in time where it seems that no matter what brand we buy, it turns into trash in a few years. I am a strong believer that this is done on purpose. The biggest issue with "smart TV's " is that the firmware takes control of it. Once the OEMs stop supporting it or do some weird updates, it all goes down hill.
What you are describing sounds so much like a firmware issue. Let me see if I can find what version your TV should be on etc. Don't spend money on a mainboard just yet. Cost is about`USD$ 200 from Sony and around USD $100-$150 at other places. I can vouch for Shopjimmy and TV parts Today since I purchase from both. No, I do not get kick backs and ultimately, you should always purchase from wherever you feel comfortable.
