Red flashing power light blinking


These flashes are fault indications, and are called blinking codes. By the number of flashes occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. If you wish to get more details, check the site linked here

No picture or sound


Try changing the input device to something you are sure works. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

Insignia NS-32E570A11 no picture or sound


Just FYI: I had a friend with an Insignia NS-32E570-A11 with a backlight problem, and it turned out to be one of the actual LEDs in the backlight array was burned out, causing some sort of over-voltage condition that made the backlight sometimes work, and sometimes just flicker for a moment at TV startup and then turn off. We took the panel apart and bypassed the one bad LED (it had a dark spot on it and failed continuity - you can test each LED with a continuity tester and see them light up!), and now the TV/backlight works! Be aware this is tricky bypassing the bad LED, as it is ultrasonically welded to the LED array strip (same technique used to make ICs), so you need to be a very good solderer to bypass it without it breaking the connection.

Insignia NS-LCD19 is not producing a picture


You might need to change the input on the TV. I'm almost certain that it will have a DVI and Coaxial input among others.

Check the monitor for an input button or pull up the menu and see if there is different input selector.

Insignia lcdtv32 poewr on but no picture


You need to check the 12 or 24v source coming from the power supply to the inverter board, that's the board usually to the left and rather tall. Get your meter set, then turn the set on and see what happens, if the voltage comes up and then shuts down, you'll need to pull the plug for the inverter and measure the voltage again. If it stays up you have a bad converter board, if not then it's in the power supply, that's good old fashion trouble shooting from there on.
