What an incredible array of emails. First, he is not a klutz, very
athletic, quite coordinated, only 11 years old and was basically unhurt.
The TV is very heavy and he could have been hurt quite badly.
Second, I plan on taking the TV in to see if it "can" be serviced. I hope
they can improve the quality at minimal cost.
Thanks for your assistance.

Choose the shop carefully because some places are staffed almost
exclusively with entry level tech school graduates, meaning they don't
pay decently enough to retain good technicians. Those places also
tend to charge the most. It might be best to go to a place that's
worked on several big screen TVs because other shops may not have much
experience converging the colors since it's not economical to do with
smaller TVs, and smaller TVs also don't have nearly as many

If you look inside the TV yourself, check for any small magnets that
may have fallen off. They may look like buttons or be narrow, thin
strips of metal. You should be able to see from where they fell by
the dust or glue marks, and put them back the exact same orientation
because if you flip a magnet around the picture can actually be made
worse. Silicone rubber sealer is a good glue for them. It's possible
that a rubber wedge that goes between the yoke and picture tube has
Adjusting the color convergence with the ring magnets requires letting
the TV warm up for at least 30 minutes and then loosening a locking
ring and possibly even cutting through sealer. The voltage and
current in the area are high enough to kill, so first read the
precautions mentioned in www.repairfaq.org, and don't do the work
alone. Better yet, if you're not familiar with working on high
voltage devices, don't do anything, and don't assume that you'll be
protected by wearing rubber gloves (can actually increase danger if
your hands sweat and the gloves have a pinhole break in them). One
pair of rings, either at the front or the back, adjusts the red
"purity" (make picture all red, adjust until other colors disappear),
another pair adjusts the red-blue convergent, the last pair the
green-violet convergence. The latter 2 pair are moved together to
adjust the horizontal convergence, while changing the angle between
each magnet in a pair adjusts it vertically. The alignment will
change after the locking ring is retightened.
TVs are front-heavy, so if you can't carry it in its original box and
packing, transport it with the front pointing downward and on about
2" of foam padding.
Jesus H, man. I know you were trying to be helpful, but you
just wrote him 5 paragraphs of "HOW TO" and buried deep inside
of it you whispered "be careful, fatal high voltages present".
The guy obviously has no experience inside of a TV cabinet.
I sure hope he took the time to read your buried disclaimer,
or his son may be burying him.

Try this. Disconnect the power. Open the covers. Reseat all the
electrical plug connections, meaning push them in to make sure they
are seated properly, Do so especially for the connector at the back
of the picture tube. If this doesn't improve the picture good luck.
One more trick you can try with the TV powered on. Use a wood dowel
or a long artist brush's handle to jiggle the cables around. If the
image is unstable, you have an idea where to look to do a fix. ( eg.
a cracked solder pad)
If you feel that you have to adjust something use either a marker pen
or "whiteout" to mark the original positions. Pull of the power cord
first. If the adjustment doesn't work at least you can restore the
