    Sencor TV SLT24F26M4 Glitching, definitely not caused by PSU

    Hello,
    this TV works perfectly, but everyday i must made about 3 restarts.
    Because if i turn it on, it hangs, or making sound and picture noises and FullHD signal over hdmi causes freeze and blue/black screen everytime.
    Here is a video of issues described:
    https://www.youtube.com/watch?v=Gba2roopmSQ
    Is it caused by capacitors/stabilisators?
    I measured capacitors and they have good esr/capacity, i add some more capacitors to 12V rail, but its not helped.

    Thanks for any suggestion.
    Regards.

          Pictures of your TV boards would help. However, IMHO I think you have Main Bd problem.

              I will post some images soon.
              Interesting fact is that, after few restarts the TV works whole day, until powering it off for some hours. Glitches are not input dependent. Maybe on TV tuner its glitching less, but still glitching, especially on HD channels.

                  Sounds like a BGA failure, reflowing the large processor on the main board may help.

                  A working TV? How boring!

                      Or voltage reg for the Cpu, most these monitors use non bga Ics.

                          What caused the BSOD?
                          by Gibon378
                          Hello there!
                          I was doing some usual stuff, browsing the internet, listening to music, coding, etc. and my computer froze. It looked like the website couldn't process the request (logging into the account, there was the loading symbol) and it took a few seconds, then my computer totally froze except for the mouse cursor. It lasted for about a minute and I got the BSOD. It happened yesterday and today (just now).

                          I managed to get the MEMORY.DMP content, but I don't really understand it. Could somebody help me?

                          Code:

                          Hi all

                          The glitching is random & almost seems servo related .

                          Hello everyone.

                          Did anyone seen this kind of fault before?




                          As you can see the menu graphics are distorted and the background is this dark greyed striped mess.

                          I found that these TVs have a common problem with the mainboard, especially with the CPUs soldering.

                          Should I try to reflow it with my hot air station and see it if it helps?

                          Thank you...

                          by peterkos2
                          Hello.
                          I recently rummaged in this Sencor TV and found a faulty backlight. I managed to replace 5 LEDs and the TV started up.
                          The problem is that the TV restarts itself and I uploaded the FW from the link - it is an older FW than it was there, but it works, only those restarts.
                          From what I found, I was surprised- the restart only takes place while watching the three programs every one and a half minutes. Other programs without a problem.
                          Has anyone encountered anything like this?
                          Can't advise on how to get to the service menu? I didn't find anything specific....

                          Sencor SVC7020BK robot vacuum cleaner problem
                          by Awesomerp
                          Hello I have been trying to identify and fix a problem with a robot vacuum cleaner, which when switched on cleans for like 3-4 seconds and stops, all the driving, sweeping and vaccum motors stop.
                          On the pcb from a battery connector up to a main microcontroller everything seems to be fine (vcc pin input is 5v constant when a switch is switched on).
                          And the switch itself is fine looking at the quality of my soldering
                          Red LED keeps blinking during those 3-4 working seconds, and when the robot stops LED just remains lit.
                          The green one for some reason does not even...
