Question about Televison & Video

Insignia ns lcd32

Yesterday, I turned on my TV to find red green and blue thin vertical lines on a black screen. It then progresses into blue and white lines that are thicker. The picture returned but the thick blue and white lines started up again after 15 minutes. Similar results today. The audio is fine. What is the cause? Thanks in advance.

Check the connecting cable to display paned and its T'Con board [LVDS cable] for any loose contact with its either end sockets. Reseat it once and check. If you wish to get more details, http://electronicshelponline.blogspot.com/ Pull up previous posts there, either by type in the model name to your set in its search box, or view it in Timeslide option.

SOURCE: vertical lines across my entire screen

My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

Good day!!!!
If your TV got a lines,no picture and sounds?
That problem is usually happen when the main board or system board is not initiallize..
There are 2 cause of that problem #1 is the power supply---if the power supply got voltage drop your main board is not initialize...Commonly cause of voltage drop is faulty capacitors..You have a better chances if the faulty capacitors is looks like leak/bulged on the top so that you can easily find it through visual check and you don,t need to use special meter could capacitance meter to trace the faulty capacitors...
#2 is the mainboard itself---if the main board is faulty or not initialize..usually the processor IC is bad andits not for D.I.Y it can repair only on the manufacturer...but the mainboard is available on the market that is the only way to end this issue if the main board is bad...

Color separation ~ Insignia 32" NS-LCD32


1. Unplug unit from wall for 3 minutes;
2. Press & hold Power button for 1 minute;
3. Plug in unit.
OR:
1. Unplug for 3 minutes.
2. Plug in unit.
3. HOLD Power Button as unit starts ... hold until the unit flickers on then off twice.


This effectively returns the components to factory specs, much like resetting a computer. It offers a *temporary* fix, lasting 45 minutes to hours. All depends on the unit.

Mom has an Insignia 32" with the same color separation problem, which worsens as the day progresses. Best results achieved while television is cold.

Dust in the unit could contribute to the problem ... try to keep the unit dust free as possible.

Unfortuntly you have a panel that is going out. This is not cost effective to fix.

Most likely either the main board (processes all signal) or even an issue with the power board (supplies wrong voltage somewhere).

In either case not cheap.
