Question about Televison & Video

1 Answer

I have a Insignia NS-LCD26A and all of a sudden it has no display or sound. The green power light comes on and I have to hold the power button for 5 second to turn it off?

I have checked all of the voltages from the power supply and they all seem good and also checked then at the main board. I read a blog that talked about "re-balling" the video chip and I have done this process several time successfully on laptop motherboards so I tried it. It worked! but only from a few days... so I tried it again... same thing happened worked for a few days then dead again... I am only guessing but it seems to be the video chip so if the main board is replaced it should correct the issue?? Anyone have any thiughts or have seen this behavior before?? Thanks!!

You need to check the 12 or 24v source coming from the power supply to the inverter board, that's the board usually to the left and rather tall. Get your meter set, then turn the set on and see what happens, if the voltage comes up and then shuts down, you'll need to pull the plug for the inverter and measure the voltage again. If it stays up you have a bad converter board, if not then it's in the power supply, that's good old fashion trouble shooting from there on.

SOURCE: 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.

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.

I have a Insignia 32 inch LCD TV Model number NS-LCD32. It recently started displaying no inputs. The backlight comes on but no inputs/ no sound. Green lines display if you press the menu,input, channel...


The first troubleshooting step would be to measure all the voltages from the power supply to the other circuits boards specially the 5 volts going to the main board. If you have the following: Insignia 6HA0112010 Power Supply, check FU502 for open conditions.
If all the voltages appear normal, then the main board should be replace since is hard to find individual components for a component level repair.
Let me know if you need further assistance.

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

The problem i have seen is the main surface mount IC ( the one with the heat sink) runs hot and the connections go bad from expanding. poor design. somtimes pressing down on the heat sink while its on will yield a picture and then goes out.
