Hi i am new here and just wanted to get some feedback from the pros. Have a samsung here with no image but has sound with blue screen. I guessing its the tcon board its getting 12 volts. I unplugged the left side of ribbin cable from tcon to panel and left side of panel goes white right stays blue.then did same on right side with right side going white and left stays blue. Any help would be appretiated. Only thing i havent tried is testing the fuse on tcon board.

Re: Samsung UN60F7100AF blue screen no image with sound
Test it, black - probe on chassis ground and red probe on each side of fuse, should be around 12 volts each side. -

Hi everyone,
I've got this Samsung here that would be stuck in a boot loop.
After opening up and doing the tape block method, I was able to get it to turn on and play sound from the HDMI input, but with a blue screen.
Does that mean there is another combination of pins that I need to block in order to get a picture, or is there something more serious, faulty mainboard or faulty panel?
Thanks in advance -
I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -

Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same... -
Hi , I've recently replaced the screen in my Samsung galaxy ao2s, at first it wouldn't even turn on, it had the charging symbol on the screen when plugged in but the green circle wasn't going around to show it charging....
Ive eventually managed to get it on and working but it's very temperamental...
The battery icon always reads as 50% , when the phone goes into lock screen mode i sometimes can't get the screen back on unless I plug the charger in to get it to light up, also it keeps putting the camera app on.. u think it could be something to do with the side buttons. ...05-26-2024, 12:05 AM
