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.

I have a Insignia NS-L32Q-10A that will not power on. Now power on light or standby. I have replaced the power supply already. All caps look good and fuses check OK. What next???


ok, when you plug in the set, does the power light come on? Assuming you ordered a power supply in good working order, you may very well have a faulty main board. The power supply produces standby power that the main board uses to power the standby/power on light. Your main board also uses the standby power to provide the "ON" signal to turn on the rest of the power supply.

Insignia ns lcd 32 wont power on


When you plug in the set, does the standby light come on? Most likely you are dealing with either a failed power supply or main board. I would start with checked the power supply for bulged capacitors.

Tv has sound but no picture


This is almost certainly a problem with the backlight power supply, not the ac adapter. If the backlight isn't working, you will see nothing on the screen.

I have an l.c.d t.v. and the pic went black and the vol. is out but the power light is still on and it blinks 15 times


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

This is a problem that should be taken in for service as there could be many problems causing the problem. The power supply could not be supplying voltage to run the video card or you could have a failure in the video card itself. Try calling this number for Insignia Customer service help. 1-877-467-4289. Hope this helps you with your problem.
