I have an insignia ns-39d310na15. The power LED comes on however the TV does not. The LED does not blink and holding the POWER button down for 60 seconds does not either

You can just buy a new remote. Test it using the smartphone front camera trick. Or it is the television that has no signal, do a Power Reset. Pull the mains plug for 5 minutes. Press and hold the power button on the set for 1 minute. Plug back in. Also check the input leads on the back for whatever is supplying the signal, Cable, Satellite, OTA, then check the Source button on the remote.

Failing power supply

You'll need the LED driver circuits to operate the LEDs outside of the TV. Sometimes they reside on the main board or the power supply board. Some models have a separate board. Follow the wires from the LEDs back to see which one you have.

Here is a link to the INSIGNIA NS-39D310NA15 manual:

Refer its user manual for details.

Try a different hdmi cable. If it does not detect a device hooked to the hdmi it won't let you select it

"Blinks a few times" implies the TV is flashing a fault code at you. If you can find a service manual for your model, count the number of blinks and look it up in the diagnostics section.

However, the most likely problem is a burned-out electrolytic capacitor in the power supply. These are usually easy to identify visually; the top of the can-shaped capacitor should be flat, but may be bulged out and may have brown or black material leaking from the vent scores. The photo below shows a bad capacitor to the right of a good one; both have black plastic sleeves.

If this is the case, replacement capacitors are relatively cheap. However, you should look for the following criteria in choosing a new part:
>Capacitance (uF): same as the original, or 10% higher if the original value is not available
>Voltage: same or higher
>Temperature: Maximum temperature should be same or higher
>Physical size: should fit in the space occupied by the original; if buying a taller unit, make sure it will fit when the back cover is reinstalled, and make sure the capacitor will not touch heat generating parts such as heat sinks, resistors or large transistors.
>Ripple current: get the highest available without compromising too much on endurance. Ripple current may be specified in mA or A; 1 A = 1000 mA. Sometimes you can get a better rating by going to a higher voltage part, but physical size may be a limitation.
>Endurance: Try to get 8000 hours or better.

I usually use Panasonic FR1 series capacitors, although United Chemi-Con EKZN capacitors are also worth a look.

power button is the little nipple between the phone and play/pause pictures on right side. You hold down for 2 seconds until blue light comes on to turn on.
Too shut off hold down button 4 until red light comes on.
if want too pair with device hold button down 6 seconds until light blinks blue red
pass code is 0000

Samsung DVD player codes: 20490, 20573, 21932, 21075, 20820.

With device turned on press DVD button on insignia remote then press and hold setup until the red led light blinks twice. enter code and it should blink twice again. press power button to check if code took. If not, try another code.
