Insignia NS-LCD26A LCD TV no picture or sound

I also have to issue with no picture (black screen) or sound... I have checked all of the prower supply voltages at the board and at the main board and they all seem good. I did heat the video chip with a heat gun to see if it nay be bad solder joints and the TV started working! but only for a few days and the problem came back. I have done this heating of the video chip 3 times and the problem returns... I have tried all of the inputs and no picture. The green light comes on solid when the TV is powered on but i have to hold it for 5 seconds to get it to turn off?? I have had feedback that it may be the T-Con board.. How do I troubleshoot other that checking the voltage to the board or simply replacing it?? Any feedback would be appreciated!! Thanks!

SOURCE: No Picture & No sound. Red LED, Green LED, Red LED.

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

I suspect that your supply has gone bad. You will need to find the service manual for voltage measurements. If you want to get replacement boards many can be found on ebay or you can check www.shopjimmy.com they stock boards for many units and I have had no problems.

Its 100% sure that the source of the problem is the backlight inverter board. The fact that there is no backlight confirms this. You will need to replace the backlight inverter board to resolve this problem. If you can get me the part number off the same I can find you a replacement

I have a insignia.MODEL NS-LCD26A. SERIAL #2881LC26HA37H05804. WHEN I TURN IT ON THE SCREEN IS JUST WHITE. WHAT IS WRONG?AND WHAT SHOULD I DO?


It sounds that the main digital board to this set is not functioning. There are many reasons for this, and is not a user repairable fault. Contact any service technician.

Insignia (ns-lcd26a) picture problems


ns-lcd26a
Hi,I fixed my here's issues i had and the fix i did..
ns-lcd26a
Every now and then i would get snow and a pink picture.
Then tv stop turning on .

To fix i seen on main board capacitor cp25 and cp28 near the heat sink was bad
They were both 470uf 35v...
on the power board i seen c531 47uf 50v was bad.
i also heated up the heat sink on the main board to resit the chip ,,
and tv now works

I didnt bother putting the huge shield back on main board i figure it was a issue to over heating the cpu instead take the hit to the brain from the fcc radio wave lol

First do the 3 caps and see if it works if not then do the blow dryer to the heat sink on main board

I have the same issue with a Insignia NS-LCD26A


I would suggest trying to repair the board first before buying a new one (unless you get a great deal on a replacement one). Its possible it was something simple like a fuse or busted capacitors.

Open up the TV and take out the power board and check it for any busted capacitors. Also check the fuse(s) with a multimeter. Try replacing everything with a soldering iron (shouldn't cost more than $10 for a fuse and capacitors). Try and see if it makes a difference. ONLY DO THIS IF YOU ARE CONFIDENT and SAFE with that type of work.

Insignia LCD TV 26" Colored Streaks/No Picture


You have a bad LCD panel. The cost of a repair would exceed the value of the unit. Panel will probably cost, if you could find one, around $300-$800.
