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?

So here we go with another screen short TCL. For this exercise left and right will be reference looking at the screen.
The person I got this TV from said the color was bad in a vertical fashion about 1/4 of the way over the left side of the screen. Shortly after the symptoms below started.
Power Supply, main and T-CON board are working.
Symptoms: The TV has backlights but no picture with both FFC's attached to the T-CON and does not respond to the remote or buttons, and the TV appears to continuously re-boot.
Unhook FFC from left side... -
I'm working on a Hisense 58” R6E3 $398 Walmart special Roku TV. I picked it up free as the previous owner just said the picture went black so I assumed I'd be doing LED strip repairs. As it turns out the backlight is working fine, the TV responds to remote signals as I can here the typical Roku menu sound effects. My first thought after some typical voltage checks was a bad t-con board so I ordered an eBay damaged set pull for $5. Swapped it out and no change.
Before I order a replacement main board, I wanted to see if anyone else had seen similar issues with this set? I pulled... -
Hi
Really stuck on this TV
I'm thinking it's a bad screen ?
Voltages all seems good
Tcon 12v ok
Remove one tcon cable at a time no half image on the screen just backlight and no picture
even tried the tape trick still no luck
Thanks... -
When I turn tv on, the backlights come on but there is no sound or picture. I have read that these tv's have problems with the panels going bad but the "no sound" has me questioning if the main board is bad. Is there a way to troubleshoot the main board to determine if that is the problem? -
This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...
