When I go to turn it on the red light turns blue and I have no picture

You have two problems: blue lines is convergence problem and the blue screen and shutdown is Blue Screen control is up too high.

The mainboard needs to be replaced

so i had the same problem. red light came on, but no blue light or anything on the screen. it turns out that there were some capaciters blown on the circuit power board. unless you have a good understanding of circuit boards, its not a quick fix. but for someone who knows their electronics, its not too hard, and its not expensive to fix, unless you bring it into a store. but the supplies needed arent expensive. good luck

I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.

THIS PROBLEM HAS HAPPEN TO ME WHEN MY LAMP WAS
ABOUT TO DIE. WHAT I DID WAS UNPLUG THE TV SET FOR
A SHORT WHILE, THEN WHEN PLUGGED AGAIN IT CAME ON BUT THE PICTURE WAS DIM AND THE LAMP ONLY
LAST FOR FEW DAYS AFTERWARDS.

you probobaly. need a new bulb, my dad had the same problem. he orderd a new bulb off the internet and now it works just fine

btw for anyone experiencing these problems with the infamous "is-lcdtv32" byd:sign is the same manufacuterer as insignia, its the same company with a different sticker. i know this isnt a solution, but parts for all discontinued insignia';s can be purchased thru byd:sigh(by design). hope this helps .

Gentlemen, I have seen people with this problem and it requires the replacement of the light engine, search AVS Forum, for more information. Understand it is not cheap, hope you have ext warn.
