lost component signal

[rigmancam]

I have great sound but have lost my signal from components completely. However the screen and menu still works. What can i look for?

If it helps model number is D52W26 chassis ITC222

5960These Itt122 chassis are a pain,first check for bulged capacitors in the power supply you may be losing power to the tuner/video output.Also the if the convergence ICs are bad,sometimes you lose video.They are on the small board far left mounted up above the power supply.The tuner could also be out,the easiest way for you to check the tuner is get an old VCR and hook to the tv.If the tv gets channels youre tuner doesnt work,or is not getting power.

Any brief explanation about this?
