Question about Insignia 19 in. Widescreen Flat-Panel LCD HDTV

Insignia Ns LCD-19 Turns on but no sound or picture

When I push the power button it blinks several times, but won't turn on, then I push it again and green light comes but there's no picture or sound for a LONG time, 30min - 1 hr, is different every time. Then when I get finally image and sound, I try to change the chanel and the TV marks that the channel changed but it stays in the same one..... Then after a LONG time you are able to change the channels like nothing.

So I did the channel Auto Scan and now is worst, Now after all this long process the only channel I can see is channel 12, tha's the only one that it found and it's connected to the cable, So I put another TV there and connected that one to the cable and it works just fine.... Is there a solution, what can I do??

Thanks

Insignia is Best Buy's store brand which is an LG tv. The power supply board needs to be tested to see if all the voltages it produces are present. If they are, then look at replacing the main board.

SOURCE: 26" Insignia LCD TV will not power up. Green Light Blinks 1x

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

Red flashing power light blinking


These flashes are fault indications, and are called blinking codes. By the number of flashes occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. If you wish to get more details, check the site linked here

Locate reset button on insignia ns-ltdvd 19-09, and the reset procedure to follow.


There is not an external reset button on this TV. To reset to factory defaults, enter the onscreen menu system and highlight the OPTION icon using the arrow keys. On the resulting screen, select "Restore Default." I would also recommend power-cycling (turn the TV off and unplug for several minutes) as part of your reset procedure. Additional details can be found in the owner's manual.

No picture but have sound.


There are several possible causes for this problem, so it is best to have a technician diagnose and repair it. You may obtain service by carrying your TV in to the retailer of purchase.

Insignia NS-LCD19 is not producing a picture


You might need to change the input on the TV. I'm almost certain that it will have a DVI and Coaxial input among others.

Check the monitor for an input button or pull up the menu and see if there is different input selector.

Picture won't come up


Insignia is Best Buy's house brand. If it's still under warranty, contact Best Buy. If not, find an electronic repair shop you think you can trust and take it in. There is absolutely nothing you (unless you're an electronics technician) can do to fix it. I know that's not what you wanted to hear, but, that's the way life is now.
