Re: Insignia NS-42L550A11 no picture
An issue returned last night. 2 days of working fine, and suddenly the video started to go.
The right side had green vertical lines that affected the TV menu as well as the video feeding in, so it's definitely the TV.
The video was also ghosting really badly, where everything was basically blurring together. After a restart it worked briefly again, but soon repeated the issue.
Before this issue, the TV took about 15 minutes to "warm up" again, too.Comment

Re: Insignia NS-42L550A11 no picture
Here are the images of the TV going out.
This is in-game, and all movement, environment etc is blurring together.
This is with the game turned off, and just built-in TV images.

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... -
Hello, I'm new to the group and to trying to repair a LCD TV. During the past few years, I've been collecting/repairing/restoring vintage personal computers (Commodore, Apple II, Atari, TRS-80, Texas Instruments, and Timex Sinclair). This has been my retirement hobby. Now I've gotten interested in trying to repair a LCD TV that I have and used regularly when working on vintage computers.
The LCD I'm working on is a Insignia NS-LCD019. I've downloaded the service manual that I could find, but it must be a different revision since not too many items in the service manual match the TV... -
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 realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.
The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.
Original T-con:
Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.
First replacement T-con:
I thought it might be t-con and ordered new t-con from china(supposedly tested)... -
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
