You can actually remove RPMB key on a emmc and program a new key if you know a new key which will reset the counter... -
Hi how do we find the corrupted part on a emmc ?
The Rt809h reads emmc in a different way so any dump from that won’t work in other programmers...Leave a comment:

Emmc dump for XBR-65X850D required
Need emmc dump for XBR-65X850D or for 55” version, board number is 1-980-832-11, this is USA board and Europe and UK board has same board number but board is slightly different and the dump didn’t work so really need the correct one, I don’t mind looking after the person with the dump -

Recommendation for programmer for Sony android tv emmc
Hi can anyone recommend me a good programmer that is capable of programming Sony android main boards as the boot loop issue is common, and want to start programming them preferably in circuit as I have heard it's possible as there's many pictures of the points to solder to, also I noticed some require rst_n connection and not all programmers have that if your doing it in circuit -
Re: Anyone recognise this emmc programming software and device ?
Thanks for that, I was hoping it would be a lot cheaper than that, it's out of my price range, I've got RT809H and wanted something maybe better, Easy jtag is way too expensive aswell...Leave a comment:

Anyone recognise this emmc programming software and device ?
I saw this software on a foreign forum where you have to pay to get advice but the website doesn't seem great when translated and hardly anyone speaks English there, I saw this software they use for programming the emmc on Sony android boards but can't figure out what device or software it is, here's a picture of the software and maybe someone knows what it is ?... -
Re: Samsung QN65LS03RAFXZA (65” The Frame) Backlight Repair
Did you repair it, shouldn't be too hard as this model is not a slim model and the bezel on the front goes all the way round so be easier than the newer ones which have no bezel and screen is glued in...Leave a comment:

I know it's a old thread but it wasn't a mistake from SJ, qleds do use normal led backlight strips, some leds are blue but some are normal white leds...Leave a comment:

Re: Sony kdl-46hx853 no power
Sorry I'm no expert, and I never always had access to the tv, I still don't have access at the moment , still waiting for my work to open, I might be able to go there weekend and I can report the voltages, this main board doesn't have any big regulators, maybe there's some really small smd regulators and there's a couple of dc concert it's near the connector for the wire that goes , to the power supply , I did check the 3 smd fuses and they seemed ok , I'll see if I can fetch the tv this weekend...Leave a comment:

Re: Sony kdl-46hx853 no power
Yh I can borrow the main board again and I can try comparing some readings , what kind of things shall I take readings from?
Maybe things like dc converter chips but what else shall I compare ?
Because we got no standby light on the faulty board, what area of the board shall I concentrate on or try and troubleshoot ?
I did check if anything's getting got but I never felt anything getting hot, maybe a small cap might be getting hot but I missed it when I felt...Leave a comment:

Re: Sony kdl-46hx853 no power
Thanks for everyone’s help , I’m not being awkward or ignoring advice, it’s just 1 reason is I don’t always have access to the tv and the other reason, I did measure the voltages but I never wrote it down , which is my fault bcuz I just matched the voltages to the service manual and what’s written on the board and I thought that would be good enough, bcuz I did try another power supply and it made no difference and I tried another main board from 55 inch tv yesterday and tv worked perfectly , so I presumed it’s pointless...Leave a comment:

Re: Sony kdl-46hx853 no power
Yh that's the problem I don't have the tv at home just the boards And that's one of the reasons I never posted the voltages, and uk is on lockdown so I can't just keep going there all the time , maybe I can bring it hone after bank holiday on Monday , but I'll look for 10k resistor, I don't know if I got one , but does it have to be 10k , I got 1k for sure but I haven't checked if I got anything close to 10k...Leave a comment:

Re: Sony kdl-46hx853 no power
Yh I will do that post the voltages but I have access to the boards at the moment as the tv is at my work place , Maybe I could try jump starting the power supply , but I’m no expert, I just want to know this for knowledge but now I know which board is faulty why are we still concentrating on the power supply and if the service manual says it’s definitely the main board , then why are we still concentrating on the main board ?
You said by the control voltages we will know which board is faulty , but I did say I...Last edited by imran333; 04-10-2020, 08:18 AM.Leave a comment:

Re: Sony kdl-46hx853 no power
Quick update my friend has a the same main board from the 55 inch tv sane model but 55 inch, tv works fine with it to my surprise , but he wants too much money for it £50 which I don’t have right now which is a discount as he’s selling it for way more online, so just thinking how to trouble shoot the main board as I got similar board which has same components on which I can Salvage parts from, but I’m stuck on what to check on the main board , as I checked for any shorts on smd caps and nothing getting hot, but some advice will be...Leave a comment:

Re: Sony kdl-46hx853 no power
About the backlight test I wasn't checking the voltages with the backlights in circuit , I removed the wires going to the backlight driver and checked with a backlight tester to see if I got any difference with the voltages on each set of wires and the voltages was all the same on each set of wires, normally if leds are bad, I'll either get short circuit or the voltages will read very high on the strip that has a faulty led, but I removed the backlights to check to rule them out and all functioning...Leave a comment:

Re: Sony kdl-46hx853 no power
I removed the backlights to check them and they are all functioning and I borrowed a working tcon and backlight driver but still same issue , the only board I haven’t been able to borrow is the main board as my friend who sells parts has already sold it and next I’ll post results of power supply voltages, but I have already tried replacing that board but still same problemLast edited by imran333; 04-09-2020, 12:33 PM.Leave a comment:
