    insignia ns-50d550na15

    Hello All!
    Would anyone have a schematic/service manual for an insignia ns-50d550na15 ?
    I have some wires detached from the infrared sensor plug and need to identify their locations to reattach.

    Many Thanks

          Capacitor detached from PCB – RTX 2070 Super Founders Edition

          Title:
          Capacitor detached from PCB – RTX 2070 Super Founders Edition

          Description:
          During maintenance on an RTX 2070 SUPER Founders Edition, I found a capacitor lying on my desk after reassembly.
          I did not notice it detaching, so I am unsure of its original location on the PCB.

          Procedure performed:
          - Removed backplate
          - Cleaned heatsink and PCB with isopropyl alcohol + soft ESD brush
          - Reapplied thermal compound
          - Reassembled card

          Observed behavior after reassembly:
          - GPU powers on and operates normally under...

          Insignia NS-LCD019-09 issue: Power light turns blue for 3 seconds, the flashes red before going solid read again
          by cajoeg
          Hello, I'm new to the group and to trying to repair a LCD TV. During the past few years, I've been collecting/repairing/restoring vintage personal computers (Commodore, Apple II, Atari, TRS-80, Texas Instruments, and Timex Sinclair). This has been my retirement hobby. Now I've gotten interested in trying to repair a LCD TV that I have and used regularly when working on vintage computers.

          The LCD I'm working on is a Insignia NS-LCD019. I've downloaded the service manual that I could find, but it must be a different revision since not too many items in the service manual match the TV...

          Insignia NS-LCD19-09 (third and final post, hopefully!)

          I have been going round and round with this one for a couple of years. It's a 16x10 display that allows you to size your OTA picture correctly to 16x9 and that makes it kind of cool so I really want to keep it on my OTA monitoring wall. Accidentially let a screw roll under the powered power supply board and ended up replacing the MOSFET drivers for the inverters, then one of the Schottky rectifiers for one of the supplies, then the PS caps becuase I fired the parts cannon at it one day.

          Problem was no cold startup; it would only startup when you applied a heat gun to the board....

          Insignia NS-LCD19-09 no standby LED; (new problem)
          by valvashon
          Having a new problem with the 19" Insignia that I modified with one of my automatic turn on circuits. That is now completely disconnected so that is not the issue. I was doing some modifications on that circuitry and managed to short something out on the underside of the power board.
          Actually found and bought the service manual (who knew it was even available?!) which brought me to the High Voltage Startup Circuit controller chip.
          Looking up that chip number- LD7575APS brought me to the attached datasheet. I have marked my voltage readings on the schematic sheet (open in new...

          Insignia NS-50F301NA24 No standby power, no +Va, Vm, +Vl etc.
          by tbsmith
          There is voltage on the bridge rectifier and main caps (163V). Fuses all check good. One of the smaller electrolytic caps (C9112 which is 50V, 100uF) looked bloated, it measured 60uF with one tester, and defective with another. I replaced it temporarily with same uF rating, higher voltage since I don't have the exact one. I also found that one of the switching mosfets (for lower voltage DC supply I think) was shorted. It is a 50R800CE which I didn't have, but had something with the same voltage and current rating and a similar Rds. None of these fixes helped. I'm out of ideas. Any suggestions...
