I have like a Phillips Series LXI Im pretty sure. I received it in a repair class and me and my buddy are stumped its picture is very dark and adjustments do not help. When my buddy looked in it he got shocked by the wire going to each of the lamps do you think that would cause a problem with the brightness

This sounds like the vertical output IC has stopped working. If the vertical pulses are missing at the yokes then the picture shuts down to protect the CRT's from being burned by the intense thin white line through the center of the picture. I have seen many of those TDA vertical output IC's fail.

When you push the power button, the screen flashes a picture, and than goes dark. The power button stays solid red.

Two probably solutions:
1.-- SSB need be replace
2.-- Convergence IC's need be replace.
You need to have electronic skills. is hard to do this work.
Be careful, try to find a TV shop for help.
Thank you

its far more likely that you need a new Vertical output IC. The convergence ICs wouldnt prevent the picture. When you have audio but no video it is often meaning vertical failure. Try replaceing the vertical IC
