Re: Reboot cycle on Samsung TV: UE 40D (5700)
I replaced the two bigger 100/35 SMD caps (I only had THT caps, but never mind), since one of them had a very bad ESR and now the TV set works again.
Thanks for your help!
The two caps I replaced
Whatever works
No reboot cycle anymore and the picture is back:

I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.
The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While... -

Hi,
I have 3 of these TVs for repair with same problem of going to standby after around 10minutes and start again continuously. I have tried a new SPI 25Q40 but fault remains. Am suspecting a CPU problem as it gets a bit hotter than I expect.
This seems to be a common problem in these models. I am 100% sure it is a mainboard issue as I have fitted a spare from a normal TV from a UE40K5607 and stays on (diplay inverted but I managed to rotate in SM using a different display).
Any help appreciated!... -
Hello,
I have a Samsung DM32D display.
When I try to power it on, the red LED blinks 5 times and nothing happens—the unit won’t start.
Here’s what I have tried so far:- Disconnected the cable between the mainboard and the power supply → the backlight turns on.
- Disconnected the main T-CON ribbon cable → same issue as before, the LED still blinks 5 times.
- Disconnected one of the two T-CON ribbons to the panel (tested each one separately) → same issue, the LED blinks 5 times.
From these tests, I suspect the problem might be on the mainboard. Could anyone...08-24-2025, 03:47 AM -
I have a Samsung UE75TU6905 from 2021, with a maximum of 10 hours of usage as it has been used as a presentation TV in the office. It started rebooting, the picture disappears, the sound continues for 2-3 seconds, and then it restarts (Samsung logo with Tizen OS), after which it returns to the previous activity. I tried disconnecting HDMI, antenna, WiFi, and using different power outlets, and it seemed to improve (or so I thought). Before, it happened occasionally, but now it happens all the time, so the TV stays on for a maximum of 30 seconds.
I read on Samsung's website (reviews)...
