        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 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.

        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...

        Insignia NS-43D420NA20 backlight on no display - LCD panel burn failure
        by howardc64
        Eventually discovered a burn mark near lower corner of LCD. Here is a summary
        • Backlight on, no image
        • Disconnect right buffer board (view from front), left side display comes on
        • Masked off pin 7+8 (both ~12,5v on both left and right buffer board) from t-con to right buffer board (view from front) display works but have some lines
        • Buffer board is pretty simple
        Removed the front bezel to examine edge of the glass. Found burn mark on lower right (view from front). Plastic bezel covering the burn mark region shows heat signature on the inside surface facing the LCD panel. Last 2 pics. Bright...

        Insignia NS-32L430A11 backlight issue
        by arnard
        I have a weird backlight issue on the above Insignia Plasma that I am coming up empty on researching.

        The display is darker on the left than on the right side of the screen. It uses 4 U shaped plasma tubes. I have had it apart deep enough to tell you that the tubes are bright as they should be at the electrode ends but dim as they get to and go around the bend.

        Since it is all 4 tubes it seems like it would be an inverter/backlight board but obviously can't be a blown up component as it does still somewhat work. I'm thinking low voltage but no idea where to go beyond...
