Insignia 47" lcd plays great for about 10 mins and then the screen goes black. I have backlight still i believe when i look in vents i see lights on both ends and have some light around the edges of the tv faintly. I have sound. I have no on screen menu/display once it goes black. Anybody familiar with this i looked at power supply, main board, tcon board and see no bulging or discolored capacitors. What should i be looking for, i see many people with this issue having tcon board problems. Once before it went off it distorted the picture all weird shaped. When i cut back on it comes on immediatley normal for a period of time. the more i do it the shorter the duration that it stays on . Eventually i power it up and get the black screen from the start i guess once its hot enough. Please any advice would be good im stressed. Thanks

Check for fuses on the T con and the main board.
Post good clear pictures of the boards in good light without flash.

Re: Insignia 47lcd picture goes out after 10min, have sound
Cool, im in the process of taking the pictures now and will post as soon as possible. I did want to mention the tv power on light is blue when on and as soon as i turn the tv off it flashes a red light 7 times, is this significant to anything. Thanks pics coming soon!Comment

When i power on the tv a "please wait" image appears then goes away then nothing after that only sound
When i was removing the back cover i heard a rattle.
Removed the metal plate and the heat sink was off (see pic)
would this cause a no picture/image issue?
What is used to put back the heat sink

Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds

- without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
- when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

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,
Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
Anyway I still fully expect that there has been something seriously damaged... -
Hi all
I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.
Symptom:
No picture no sound.
When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
No sound at all.
What I tried:
1. I tried unplugging the left or right ribbon...
