The model is WD-52627, the screen flickered and then turned a light green and lavender. We still see the tv show

You most likely have a failing color wheel.this is a symptom of the color wheel losing sync. This is a common failure on a Mitsubishi TV of that age. you may be able to solve this by merely cleaning the insides. Unplug the TV and make sure the lamp has been off for at least an hour. Remove the lamp and use canned air or air compressor to blow inside the lamp cavity. Then have a vacuum ready to suck up any dust that billows out. The dust gets in the way of the color wheel sensor and causes this to happen. Reinstall the lamp and try again. If it does not let up, then you may have a bad color wheel or a problem with leaking capacitors in the power supply. With either of those issues you need a service tech to check it.

Hi Jenell

Looks like you might have lost one of your primary colours. RGB
A section of the internal electronics controls Red Green Blue.
Check for loose plugged in cables on back. Antenna or Cable
Try inputing a signal from another external video device like a hard drive.
Try a couple of hard slaps on the back to see if it changes.
If it does then you may simply have an internal bad connector or loose wire.
Make sure the air holes around the unit are clean to allow cooling air to flow.
Other than that, you will need a technician to open it up.
Cheers
