Periodically the screen will start turning green, then worsen.

I had the same problem. all the service reset would only make the display come on for a few second with no "k" on the screen - only the channel would show up. I purchased a complete set of board for the lcd on ebay, and started swapping them one by one. The inverter boards were the culpret. Tele working 100% since that board swap.

This tv the LCD inverter board is dead,that why is not sustanning backlight for the LCD screen light to have the picture.Call Polaroid for warrenty repair,this tv under a year old.

If its six months old it should under warranty?

I think I may have just solved this issue. Remove the back covers and turn the tv on until it the screen goes black. There will be a little red led that will light up when the screen goes black. right above that light there is 4 little swiches, the bottom one is labled BURN. Switch that one to the opposite direction. I don't know how but mine has been working for a couple days now with no issues. GOOD LUCK!

Given that your TV isn't even a year old yet, I would use the manufacture warranty.
It maybe something expensive as a mother board to fix. Maybe $400.
Here's the link your need to start your warranty claim:

Hi

the best thing you do is to go back the unit where it you buy because this is under warranty

Thanks!

John,

First, Id like to know how old is your unit? Also, the lines indicates in issue with regards to the lifespan of your tube. The dominant green color has something to do with a malfunctioning ray gun of your tube. However, i had encounter a unit that was resolved by simply resoldering the circuitry of same problem.
Why dont you try to resolder the board first.

Response is highly appreciated.

this unit is dead ,possoble power supply problem. you must have warranty on this unit if its only 8 months old,if not contact place of purchase and ask wath is the life expectancy of their products and your tv set it start them thinking about repairing or replacing.

your picture tube is not blown you are having problem in the color circuit there is an ic that controls that circuit,the tv is also having a vertical problem an ic also controls that circuit you will have to call a tech to repair your tv good luck
