Hi everyone,


I have an Insignia ns-LCD47HD-09...and the screen does not work. the red led works and when I turn the TV on the blue LED comes up and stays on. I have tried the unplug, unplug and hold power button tricks but they don't work. the screen does not light up, stays black. What part might I need to replace? Any suggestions?


Thanks!!

You'll need to troubleshoot either the main, power supply, or inverter boards.


Good luck,

Jim

Thanks for the reply. No on either. When I turned on the unit before, although the screen would be black you could tell it powered up. This time, nothing.

Ok then, you should start with power supply board. Connectors should be labelled at their pins with correct voltage values under the load; this means that you should forget about checking those values if you never worked with electronic parts that contain lethal voltages.
