i have the same problem with mine but it makes a crackling sound.I have unplugged and re-plugged but nothing please help

When the tv is turned on the blue light flashes it is not putting on the blue screen

light engine will be the problem

it sounds like the blue crt is failing Pull the front off and turn the tv on
When it still has a good picture tap the blue crt
if it flashes blue with lines across the screen then you know it is a bad crt

It might not be worth fixing

Good luck

I would suggest getting another optical block from the repair man. Apparently even some replacement blocks have had issues...

i think your capacitor is blown, do a google search for insignia, lcd, capacitor...
you can buy another one for about $2 but its a pain to install, you can also instead buy a new powerboard for about $80, its an east install and you wont blow more capacitors

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.

Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

Sounds like the blue convergence circuit still not working.

Assuming both IC's are good, look for open soldered-in pico fuse.

Once bowing problem is solved,then convergence should adjust ok.     

Might be a bad CRT or bad video output IC that drives the CRT that would cause this issue.
