X-ray like colors on screen/almost iridescent

Sounds like a software upgrade is needed to this TV. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

You probably will notice the flud is burned. If not, there is a metallic iridescence. This trans has to be remove and repaired or rebuilt.

check screen options. sometimes you can change the primary color's intensities(it looks stupid at 100% for all). You might have red a little low making yellow and blue show up greenish on the screen.

The player has a serious video problem, cause bad laser pickup, video processor chip, or the LCD screen is faulty. To fix this type of issue would not be productive, cheaper to get a new player.

It's just normal wear and tear, you can use any type of cookware.

There are three reasons. The LCD got damaged, change it. The connectors got loose/disconnected due to fall, have them fixed again and the display IC got damaged (hope not) as no one can repair it. The phone is scrapped if the IC goes.

your player or tv maybe set on pal secam try changing it to auto or ntsc

It sounds like the circuitry which actuates the color drives for the screen are not working, this would ba analogous to adjusting for a B&W picture on a color TV you have color but the screen shows black and white. I would get a schematic for this set and measure the voltages on the color processor that connects to the screen since you know that the external jack has color. If possible I can help you troubleshoot this, if you need me to help out.
