Insignia NS-L26Q-10A no pic or sound or light

[Joatmon]

I trying to help a friend out he has a Insignia NS-L26Q-10A that will not power up no light at all no where. I open it up and check the capacitors and I do not find any that looks bad. I check the voltage from the power supply and only have 5 volt no other volt reading.
Power supply number is 715G2907-1-3 my question is, is it the power supply or the main board?
Sorry I don't have any pictures.

Are you likely to have any pictures -without them its very difficult.

"Power supply number is 715G2907-1-3 my question is, is it the power supply or the main board?"

Its a bit like saying My car wont go- its a blue ford with v6 engine - the lights come on - my question is is it the battery, the plugs, carb , petrolpump, engine,clutch, gearbox.

Try checking any fuses and fusible resistors front and back of boards.
Loose connectors, loose components, cold joints resolder transformer joints
big resistors and big diodes.

If you have no power LED at all but have 5V standby on the power supply, start with the main board and check the voltage regulators. I have written about how to measure the above several times especially for Vizio TVs.

We are trying to troubleshoot the problems without having the TV or the boards in front of us, so good pictures are a must.
There are more than one version and manufacturers for this model.

Yes it does and thanks for the help. I'm working some long hours and will be off for a while after Thursday and I will post some pictures after I do a few more test.
