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

    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.
    Please upload pictures using attachment function when ask for help on the repair

        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.

        If you are new to this forum, we can help a lot more if you please post clear focused pictures (max resolution 2000x2000 and 2MB) of your boards using the manage attachments button so they are hosted here. Information and picture clarity compositions should look like this post.

        We respectfully ask that you make some time and effort to read some of the guides available for basic troubleshooting. After you have read through them, then ask clarification questions or report your findings.

        Please do not post inline and offsite as they slow down the loading of pages.

            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.
