    My Sony just did the same thing last night. I do not have a problem soldering, but do not have much experience inside TV's. Do I need to discharge voltage somewhere before I put my hands in there?

    Welcome to the forums.

    I moved your post to a new thread because the old one was long gone - http://forum.allaboutcircuits.com/showthread.php?t=23580

    There are lethal voltages inside TV's even with the line cord pulled. If you haven't at least got a meter to check with, poking around may be a bad idea.

    Do you have experience with high voltage circuits?

    How versed are you in electronics and circuit assembly?

    This can be done, though it can be lethally dangerous as well.

    If you feel comfortable working with circuits that retain power even when the power cord is removed, post photos of the board (both sides), and a good description of the problem.

    Be sure to discharge the CRT if present, and any HV caps. Video tutorial on discharging CRT
