Hello, I have an asus Z97-A motherboard and it doesn't start which was working properly before, the problem isn't related by ram, ram slots or psu (I changed all and nothing work), the exact problem is when you switch it on , it starts and after 1 seconds (no boot or display picture) it's off and then on cycle continuously until you power it off from psu also it's responding to the power switch for turning it off if you keep pressing it 3 or 4 seconds (power button pin has 3.3v) , also when you start it with eatx 12v socket connected this is happening (power cycle also all voltages are resetting... -
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... -
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.... -

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...
