Yes, definitely a problem in the PSU, Also look for cold solder joint and reflow them, especially transformer legs, etc.Comment

Hi,
I'm working on a HP Victus that is not turning on. When power button pressed it only blinks 3 times with charging led. I have checked input mosfets and they are fine. Also all coils are fine too. Battery was empty but I charged it with my lab PSU and laptop started on batery but is not charging. When battery is disconected and only PSU connected it takes 0 current and not starting. What can be the reason? -
Just replaced all the LED strips and successfully turned on the set and even watched some HDR content, but then noticed a small piece of dirt dead center in the screen. Tried flicking the screen to get it to drop to the bottom as well as static-charging a cloth and rubbing it to make it go down the screen, but no luck.
So I proceeded to disassemble the whole set again. You can guess what comes next.
The set lights up fine, but blinks 3 red blinks and no menu or anything else. The screen looks fine, but there could be panel damage or a short. Also the lights stay on.... -
My Samsung UE75TU7020k lights up fine when one of the ribbon cables are disconnected from the main board, lights stay on but not getting half a picture, I do the same with the other ribbon and put the other one in and lights stay on but not getting half a picture. The standby light flashes 2 times then reboots then it then tries to come back on again and just keeps looping until I take either one of the ribbon tables out (doesn’t matter which one I take out it stays lit when either one is out). I’ve tested the backlights but all working with none shorting out, I’ve replaced the main board... -
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've happened upon this TV, it came with no power cord or remote and it seems to be experiencing a common issue where the red indicator light blinks 2 times then the screen flickers as if it's trying to turn on. No picture, no sound. I suspect the functions of the TV are in good order and that the underlying issue is with the power button which is missing. It's just a white tab where the button should be which means I can't cycle it.
I wanted to know if there is anything I can do or if I should just get a replacement module with the hopes it will fix the system. Alternatively if...
