Re: SAMSUNG UE46D5520 rebooting
TV still working fine. I will reload the firmware and see. This certainly surprised me and a little frustrating as I lost my confidence and direction when this happened.

Re: SAMSUNG UE46D5520 rebooting
So TV went from not downloading the upgrade software to working! I have heard some unplugging cables and cleaning them but I did inspect these and they were clean. Either that or something else occurred?Last edited by Mungry; 10-20-2020, 01:05 PM.Leave a comment:

Re: SAMSUNG UE46D5520 rebooting
OK, I am now confused. I went to check that disconnecting cables and what state the TV was in when disconnected. I turned on TV and disconnected the ribbon cable which goes to the small PCB in the lower middle of the TV. This is a multi way L shape ribbon (Not sure but my be the Tcon board to interface?) The screen went blank with a rapid fading horizontal line until after a few seconds it was black. I thought perhaps I should have not done that with the TV on so unplugged the mains and refitted the connector at the small PCB end. Turned on TV and...Leave a comment:

Re: SAMSUNG UE46D5520 rebooting
I tried through ethernet as well and it says not download available, so I assume it is at the latest version. Not sure how to check on this TV.Leave a comment:

Re: SAMSUNG UE46D5520 rebooting
Yep, it has the folder and the original file. I tried it a few times. TV just did not want to read the file or upgrade. I also tried both USB ports. The TV only had mains and the USB stick connected. I am sure I am doing something wrong?Leave a comment:

Re: SAMSUNG UE46D5520 rebooting
Hi Diif, Yes I got the file extracted. So I have -
Upgrade File(USB type) ver 1027.0 (MULTI LANGUAGE)
: All OS

Downloads [61.71 MB]
Upgrade File(USB type) ver 1025.0 (MULTI LANGUAGE)

Nether would load on the TV. I assume it is because the TV already has this update? Maybe I did not do the reset properly? But now stuck.
Cheers,

Hi Diif, thanks for your reply. The link you sent above does not work either for me in Google Chrome. But I sorted this by using Edge Internet Browser ;-)Leave a comment:

Re: SAMSUNG UE46D5520 rebooting
OK just to update, I read about certain internet browsers not working on Samsungs website download so tried Edge instead of Google Chrome and the download worked OK.
Got both versions available on the USB and ready to go. tried them one at a time after freezing eeprom. TV stayed on much longer so I could select the menu.
Tried both and TV just says no software to download or upgrade when I try. It knows the USB drive is there but won't load the upgrade at all. I have tried a hardware reset as well. and download via hard internet connection...Leave a comment:

Re: SAMSUNG UE46D5520 rebooting
Is there another way to get the software? Does anyone else have it?
Just a thought.

Re: SAMSUNG UE46D5520 rebooting
Hi, If you disconnect the cable from the power board to the main interface board the back light stays on and TV does not switch on and off. Any other cables disconnected the TV carries on switching on and off. I have freezer spray now so will give the Eprom a blast but now I have to wait for Samsung's Website downloads to be fixed. For some reason I could not download them so contacted webchat and after 1 hour on there they realised their site was not working and is a known issue. They say they will fix it. Until I get hold of the updated software...Leave a comment:

Re: SAMSUNG UE46D5520 rebooting
I will give that a go. I have tried hardwire reset and putting PCB in freezer for 4 hours but not cold enough. I did also try lighter fluid but you have to wait for that to evaporate or you could be in trouble ;-) Looking at the video it is critical to get that chip cold. So of to shops for some freezer spray.Leave a comment:

Re: SAMSUNG UE46D5520 rebooting
I know this is an old thread but did anyone get any further with this fault?
I have a TV doing the same starting up and then turning off. It is on long enough to get a picture or channel come up and I can just get in to the first couple of menus before it turns off.
The Power PCB is whistling a bit. the problem is it is a chicken and egg situation to find out if it is the main power board that is shutting down or the main board causing it to. When you unplug the wires from power to the main board the LED back lights stay on and TV does...Leave a comment:

Re: New Members - please post your introductions here
Hi, I am new to this forum, I have been searching for information on repair of a Samsung UE32D5520RK TV and found some interesting posts here which may help me fix it. I live in the UK and have been in electronics all my working career designing High Voltage power supplies for industrial use and now spend time safety testing them to pass TUV or UL compliance.
So when I see a piece of electronics not working I do spend a lot of time working out what has gone wrong. More often that not more time than the item is...Leave a comment:
