What brand of TV is this? This sounds like bad e-caps problem. -

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

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... -
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... -
I have a XR-77A80K here. When plug in & press power, white lindicator light flashes on & off. about 30 seconds later, indicator light flashes 8x red. Checked Sony, Power reset = unplug & plug in. Factory reset involves turning it on, then pressing remote buttons when a picture shows. Well, neither of these "resets" are for a dead set like this. Anyone know what 8 blinks indicates, from the schematic? Thanks! -
Hi there
I have this set with no power, blinks power led twice.
This seems to point out to D board issue
My first question is which one is the D board?
The main board?
Or one of the power boards?
Are they labeled with this? (did not checked the boards yet)
Thanks for any inputs...
