    Dynex DX-37L150A11 - freezing up

    Hi,

    I have a Dynex DX-37L150A11 which has started to act funny. It will randomly freeze up, the screen will turn a solid magenta (sometimes green, but usually magenta) with some snow and the speakers will have static coming through them at full volume. Usually, this will last 15-20 seconds and the tv will restart itself. It will go back to normal for a few minutes and repeat the cycle, but the time it stays normal will decrease with every power cycle. There are other times where it will not respond to any inputs (remote or buttons on the side of the tv) and I have to pull the plug.

    The tv is about 4.5 years old now. About 6 months in, it would do this exact thing. It happened maybe a handful of times in the course of a month and stopped up until a few weeks ago. I thought I just got lucky since someone explained that it might be a hdmi issue. I chalked it up to that, but this definitely does not seem to be the case since it is happening so frequently now.

    I have checked all of the boards to see if there are any components that look damaged and everything looks good including all the capacitors. I have attached pictures of the power supply (that's where I think is the problem is). Any ideas on what might be the issue?

    Thanks in advance,
    Chris.

      I would say main board. Strange for a problem like that to disappear for so long then come back with a vengeance. Have you moved this tv recently to a new location ?

          Vizio TV M50-C1 reboot cycle and static on screen
          by spice_disc
          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...

          Hisense stuck in Colors cycle like test pattern.
          by nono34
          Hello,

          I accidentally changed the project ID in the service menu of my Vidaa Hisense 100U7KQ TV. When I turn on the TV, the screen displays an RGB color cycle (test mode???). I contacted Hisense, and they sent me a usb_MTK_9618.EU.bin file, but it doesn't work. I can see that the USB drive is being read, and it flashes for about 10 minutes (the screen remains in the color cycle during the firmware reading), then the TV turns off and restarts, but still in the color cycle mode.

          I want to mention that the 4GB USB is formatted in FAT32 MBR. I've also renamed the file to...

          Samsung ue55nu7021k Boot cycle
          by Yoda79
          Hi, wondering if anyone can help with a tv which seems to turn on but turn off soon after and continue to do this cycle over and over again.

          It turns on, no sound and then turns off and starts the whole cycle again. I've opened up the back and can see the backlights turning on. However when I disconnect the two straps connecting the left hard board (as you look on the back of the TV), the boot cycle stops and it does turn on and I can hear the boot up sound, however no video?

          Any thoughts, any help would be greatly appreciated.​...
