Not to worry. When you pull the back it will be a little more
front heavy so keep that in mind. Also if the speakers are on the back you gotta unplug them. Once off you can slide back the chassis &
do some checking. Zenith 26kc20 pointed out some other common
problems. Even if they are not the cause they should be checked
along with a good looking over for PC cons & swollen or discolored
caps. With the back off its also easy to move. Just hug the set
from the front & grab the edges to move. Just watch the neck!
Putting the back on agn you have to line things up but most the
time they fall nicely into place. Sometimes you may need a
second helper to tip the set a little.
good luck Zeno
