TV Pops and Bad Picture After Humid Day

M

MH

Guest
A couple days ago it was very humid and a bit warm outside, so the windows
were opened to let the air circulate. However, the day after when the Sanyo
TV was turned on it started snap, crackle, pop(ing), and the picture would
blur into lines on and off. It's been a few days as previously indicated,
and it's still having problems. Will it fix itself over time, or does it
need to go in for repair? Is there any way to prevent this from happening
in the future? Not use it for x amount of days after it's been humid out?
Thanks.
 
It is probably arching in the high voltage section . I had one that did that
only when in a damp basement . You might save some parts if you get it
serviced soon . Then again , you can take your chances , and only run it on
dry days .

Determine where the tele is arcing, at the anode connector to the crt or at
the LOPT?? At the anode connector, discharge the unit, clean the area
around the uthor connector, apply a liberal amount of silicone sealant. Let
the sealant cure for a couple of hours. However if the arcing occurs at the
LOPT your cure would be to replace it. I suspect you will find the arcing
actually occurring at the anode connector to the crt.

Well, it's no longer making any popping sounds, but there is a bit of screen
distortotion, looks like parts of it shift "right" or something, but not all
at the same time or to the same degree. I do I determine where the arcing
is? Or was. Haven't worked on CRTs before.
 
Disconnect the tele form the mains, discharge the hv connection at the CRT.
Remove the rubberboot and anode connector at the uthor button. Inspect
closely the underside of the rubber boot looking for carbon tracks where the
item was arcing. Also inspect the surface of the CRT at the uthor button and
surrounding area again looking for carbon tracks indicative of arcing. They
will be apparent under close inspection, clean both the CRT surface at the
uthor button and the underside of the rubber boot, apply a liberal amount of
silicone sealant to the rubber boot or run a heavy bead around the uthor
button on the CRT. Reconnect the anode connector assuring the pins (clips,
wire connector, etc.) are correctly inserted into the uthor button. Press
the rubber boot firmly against the glass of the CRT allowing the silicon
sealant to spread out making an air-tight seal.

The problem seems to have disappeared, for now. How do you discharge the
TV? What do I use to clean the CRT surface, uthor button and rubber boot?
Where does one acquire silicone sealent, and the proper tools to open up the
case? Has a fair amount of nuts, and some of them are rather recessed into
the case, probably to prevent anyone from opening it. Thanks.
 
Discharge with a screwdriver attached to a wire lead, the open end attaches
to the ground lead of the crt, other end to the screwdriver which is gently
pushed under the rubber boot to contact the anode leads to the uthor
connector. This will drain off any residue HV that maybe present. Advise, do
not hold onto the metal shaft of the screwdriver while doing this or you may
endure a painful shock. Cleaning material I normally use is denatured
alcohol to wipe down both the rubber boot and the contact area of the CRT.
Allow to thorughly dry, apx 20 - 40 min before applying the sealant.
Silicone Sealant: aka bathtub sealer, normally white. The screws on the
back of the tele are either 1/4 " hex screws or commonly used Phillips. Both
rather common.

Sounds like mabe you shouldnt try this, since you dont know where to get the
tools to open a tv up or where to get silicone sealant!

It can be VERY DANGEROUS to work on a crt (tv tube)!!! You can get zapped by
7,000 volts or more!!! The current out of the wall is only 120 volts! If
you do attempt this be sure to research working on crt tubes safely.. Google
it..

Now be sure you know how to safely handle a crt (tv tube) or you could end
up 6 feet under! I can't stress this enough, especially if you are not
familar with working with monitors and High Voltage equipment.

Check this link out.. It has a few safety tips and how to discharge a crt
tube.

Keep it safe, and if you dont know what you are doing find someone who does
to help you.. Dont take electricity lightly, it can very eaisly KILL if not
handled with care and respect.
