Re: Insignia NS-LCD32 black screen, varying colored vertical lines
Resurrecting this thread -
I have the same set and same problem. I already tried changing out the Tcon board and now I'm stuck having to pay too much for the main board. I'm hoping I can find something wrong with the main board that is fixable.The strong-minded rise to the challenge of their goals,the weak-minded BECOME HATERS

I'm not sure what to do next and came here since y'all helped me fix a 50" plasma TV back in 2014, which is still working!
A friend gave me an Insignia NS-50DR620NA18 50" TV that suddenly developed large vertical lines on it. He said he had no idea what might have caused it and has replaced it with a larger TV. He was going to throw it away.
I did not notice any bulged or leaking caps on any board, the voltages produced by the power supply match the voltage that the pins are marked. The backlight leds are working. I have tried cleaning the ribbon cables... -

Hi guys, I have a Vizio M58Q7-J01 and now there are some colored horizontal lines on the screen. Could someone tell me if it's probably a panel issue or something related to other parts and can be fixed? Thank you in advance.... -
Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed... -
Hi all, looking for some input on this one. I've been reading the forums for quite some time but this is my first time posting for help.
LG 47LV5500-UA
10 years old
20,000+ hours on it.
Watching TV on it last week and right while I was watching the image suddenly started experiencing the symptoms in pics. Rainbow chromatic vertical lines and alignment issues. The issue is uniform across the entire panel. It does not come and go, the symptoms are stable.
Here is what I've tried so far:
- Factory reset and cycle of picture options....
