    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.

                      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.

                          by triplefour
                          this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
                          i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
                          unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
                          according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even...

                          Lithonia Lighting versus Light of America Compact Fluorescent product quality
                          by sam_sam_sam
                          I have a Lithonia Lighting 65-Watt Gray Hardwired Compact Fluorescent

                          I also have back when Light of America had these light bulbs available for yard lights

                          The issue with Light of America was the blast boards had all most certain board failure while bulbs hardly ever fail

                          While the Lithonia lighting fixture has all most certain bulb failure

                          So I have modified the Lithonia lighting fixture to accept the Light of America light bulb and see how long this will last

                          I have only had this light fixture for not more than a year if it...

                          Lexmark 544dn power supply buzzing sound model 40x5409
                          by xl600
                          I have a Lexmark 544DN laser printer which I'd prefer not to throw away. I know I can buy a new power supply for about $150, but the printer isn't even worth that at this point.

                          The printer started acting up about a year ago. Sometimes it would power on normally, sometimes not. When if failed, it would make a single 'click', flash the LED and display backlight, then go completely dark. I got used to this but now it refuses to power on no matter how nicely I talk to it.

                          Having a workbench, o-scope, and all sorts of fancy tools, I figured I might try to find the issue myself....

                          Laptop No Longer Recognizes TV Sound Bar
                          by niimi93
                          I'll begin with the fact I don't know what change I made to my laptop that triggered this cause. I use my laptop as a pseudo PC by just connecting it to my big smart TV and using a wireless keyboard and mouse. I have a sound bar connected to the TV via optical audio toslink cable. I have game consoles connected to the TV. The game consoles and Netflix/other media apps installed on the smart tv all work properly playing sound through my sound bar with no issues. My laptop, until recently, was playing sound through the TV sound bar just fine as well. I don't know what change I made, and I don't...

                          Lumenia street light; LED power supply driver
                          by 7dalibor7
                          Hello, I've got driver module of a LED street light lamp that had an ant colony inside and probably due to some ant organic fluid driver module shorted.
                          Fuse is blown, one of the znr varistor is shorted and there is a burnt resistor from which I cant read the value.
                          Does anyone by any chance has a schematics for this driver?
                          Thank you
