How old is your plasma?

I believe the gas that powers the plasma only has x-hour's life and therfor may need to go for repair in a tv repair shop

50 plasm tv hen hooked up to dvd it s only showin in black and white

It's possible you have connected a composite output on the DVD to the component input on the TV. Composite is yellow for video, and red and white for right and left audio. Component is green, blue and red for video and red and white for audio. You might consider using the HDMI connection as well.

Lost red color

NO red should be fixable but base decision on age of set and cost to repair---if loss of red (total) I would suspect main signal board that processes all information to the screen for the picture.

Contrast really dark but seems to improve after the tv has been on several hours

You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

RCA F31317 lost blue in picture.

this symptom is characterised by the loss of one or two primary colours. this symptom can be classified into three cases: 1) loss of red colour, 2) loss of colour blue,3) loss of green color. this symptom may be caused by a trouble in the colour demodulator, in the color amplifier or in the colour subtraction amplifier circuit. in your case loss of blue colour. this is a very complicated problem that you need some special test equipment like oscilloscope and color pattern generator in order to trace the signal. tune the receiver to a color broadcast station(a colour bar generator can be used to transmit a colour signal to the set). check the Z-axis demodulator, z-axis amplifier and the B-Y output circuit for the chroma signal. observe the signal process with an oscilloscope. if the color signal is not present use a VOM to locate the defective component in any of the above circuits. check the transistors and the resistors in the collector circuit. good luck!
