Ok, i have had this lcd for a few months now, and i am having issues with it. When i first got it, hdmi input would yield bad results. It would turn off and not power on for weeks. When i finally tried a vga input the tv worked. It worked for a long period of time. Now, when i power it on i get a vertically distorted image and a loud static noise. If i unplug and plug it back in a couple times it works. I would have to assume that the issue with the hdmi and current issue are two seperate problems. None of the caps on any of the boards are visibly bad, although i know that that is not always the indicator. Any thoughts?

Hello,
I'm having an issue with the Samsung 740n's phase control setting. When I use the automatic adjustment, it sets the value to around 54 (with a range of 0-100), and the picture looks clear and sharp. However, after some time—like after playing a game—the text starts to look blurry. When I auto-adjust again, it may increase the value to 80, and everything becomes sharp once more. Yet, after a while, whether it's a few hours or a day later, the same blurriness returns, and I have to adjust it again.
I'm using the Samsung 740n monitor drivers instead of the default plug-and-play... -
Hello.
My TV is a QE65Q800TATXXC Samsung TV.
Issue : When you plug the 220V, voltages are OK on the power board and you can hear the click from the relay, but TV is not starting when power button is pressed. Red led is blinking when you press power button. But no images or sound ( Back-light is off )
Then if you disconnect the cable from the main board to the power supply, the TV back-light turns on.
Any ideas to check would be very appreciated 😊

I purchased a used Samsung TV model UA65JS9000W recently knowing it had an issue with the screen. When switched on the picture was bright both sides of the screen but a little darker in the middle of the screen. Thinking this was the back lights (side mounted LCD strips) I replaced these, however the issue is still there. I am now thinking it may be a TCOM issue, but am not sure, any advice on this would be appreciated. Also whilst changing out the back lights I noticed the the thick clear plastic sheet (maybe 1.5 to 2mm thick) below the diffusers there is cracking (up to 75mm) on the sides and... -
Hi all,
Because of two bright spots and a couple of dark spots I decided to replace the backlights in my Samsung UE48JU7000. See attached photos:
I thought all went well, but after full assembly and testing it out it turns out not all is fine. The backlights are completely fine but I have some weird issues on the right half of the screen. Since I didn't really touch the T-CON board (apart from taking out the ribbons of the display and reconnecting them on assembly) it would be weird that the issue is with the T-CON board... But based on the behavior of the service...
