Re: Hisense 75R6E3 No Picture
I could see a portion of it being damaged, but the entire thing at once? Seems odd to me....

Hisense 75R6E3 No Picture
I replaced the backlights on this Hisense TV and the LEDs were showing on certain images. Drove me nuts, so pulled it apart, got new LEDs and put it back together. Now I don't have a picture. TV came apart very easily both times and I was very carful with the panel. I've replaced all the boards for good measure and still have the same issue. Unhooking either side of TCON board still gives me a blank screen with backlights and sound. Is it really possible the panel is junk just from taking it off with suction cups and gently placing it back in place? -

I kept the diffuser sheets taped together so I didn't mess them up during installation. Really starting to lean toward crap replacement LEDs. I can't see the reflective paper causing uniform halos like this....Leave a comment:

Re: Hisense 75R63E backlight help
I had the TV back together and watched a football game on it. You can clearly see the LEDs on all light colored scenes. Darker colors look great. Messed with backlight and brightness which really didn't change anything....Leave a comment:

Re: Hisense 75R63E backlight help
Think I could have received bad LEDs? Seems to me that the light is coming out around the plastic caps and not out the top toward the diffuser. Could be wrong but that's what I see. This is a picture with the diffuser sheets removed but white paper in place....Leave a comment:

First photo is with backlights turned on and second one is with them off showing the dark spots where each LED is behind the diffuser. With them on, I get the same halo effect no matter how the diffuser is installed....Leave a comment:

I flipped it every way possible and still looks the same. I can actually see dark spots through the diffuser lense when the bulbs are off. Seems odd....Leave a comment:

Hisense 75R63E backlight help
Hey everyone. Hoping someone has some insight as to what may cause brand new backlights look like this behind the diffuser sheet. I've done about 40 TVs and never seen anything like this. Any help is appreciated as this shows through to the picture during lighter color scenes.... -
