Hi, I'm Nathan.
Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review and reply.

It looks like part of your question was cut off. I see "light blue c"?

Now I have a light blue screen with vertical black stripes

Thank you for clarifying,

that is indeed a faulty formatter board. This is a common failure, about half of the time when replacing the dlp chip the formatter board will have to be changed out as well, which is the case here.

Any recommendations on where I can buy one

The part number is ***** BK.80L88.21G,

unfortunately they are tough to find anymore, the only one I can find currently is https://www.tvpartsbay.com/mitsubishi-bk-80l88-21g-00-l8821g001-formatter-board/ though their site is not often reliable about stock levels.
