For 4 weeks, my Insignia TV was playing great. Then the screen turned
black. When I tried to turn it back on again, the blue light came on,
but the screen is, still, black. When I pressed the remote again, the
red light flashed 5 times but no screen

Re: TV was playing, then the screen turned black.
If the screen is black and you have sound then lightly press and shine a strong flashlight against the screen. If you see an image around the edge of the flashlight, an image is being 'displayed'. The problem is probably in the Inverter/CCFT or the power going to the Inverter.

I think your insignia is set for SHOP mode instead of HOME mode. I changed mine to HOME and it's working fine now. Press your menu button and then scroll down to setup. You're looking for Plug and PLay which should be the very first choice. If it's greyed out as mine was you'll have to change your imput from HDMI to TV in order to get to the P&P. Once you're in the Plug and Play your first choice is language. The second should be SHOP or HOME. Make sure to select HOME. You can skip scanning for channels. This fixed my problem with the blue light. The store uses SHOP so if someone plays around and changes something, all they have to do is shut off the TV and turn it back on. Please let me know if this works.

This television is having trouble with sync circuits. It probably has some component adding erratic noise voltage to the circuit causing the instability in the sync lock circuits. The solution is to locate the bad component with an oscilloscope by following the signal path with oscilloscope probe until you find the irregular signal and then replace the part. This part could be either capacitors or ringing resistors.It may also be a component in you solid state signal processor. You should have it tested in a service center and see if they can locate the bad components. Then see if it worth replacing with the cost of parts and labor. Hope this helps you with your problem.
