Replace the oscillator crystal and check. If the tuner has a fault, there will be no color. If the color system is selected wrong [PAL, SECAM, NTSC etc]; there will be no color. If the chorma section inside the IC [circuit] is faulty, no color will be the result. If this is the case, you have to replace the LA76*** IC. I assume that you're working with Chinese kit. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.
