Colours on TV Panasonic TX-32PL10 5/6 years old

If the TV does the same with two different DVD players, it must be a menu setting on the TV. Look through the TV menu options.

If a 4 year old 32 inch set likely cheaper to replace than repair it assuming parts are even still available.

Increase the color saturation to fight the fading and decrease brightness slightly. All of these settings are in the menu of the TV.

Tv is old the tv CRT-(tv tube) it CRT Yoking circuitry not good as before.The tv deguassing coil in not eleminating all the interference of the tv functions anymore.Move the tv unit to the right or to left like about 3 or 4 inches either sides will help for this problems.

something similar to this happened to my old T.V, with mine it started to go wrong colours, the screen started to fade, with it being 8 years old, you may just need a new one, they will eventually fully break, so its best to get a new T.V

Problem self righted.

The problem may be the LCD rinbbon connector out of place or a faulty crt board.
A repairman must open the tv and check it out.
If you really want to DIY (at your risk) all you can do is take it apatrt (disconnect from power for 15 mins or so first), unplug LCD connector and plug it back, also hoover dust inside.

I had this happen once.

Can you get into the settings mode to correct it from the screen?

your problem is in red video circuit. please get it done with skilled tech.
