Question about Hitachi 61SBX59B 61" Rear Projection Television
Hey and good day.. I can't think of a better way to describe
the problem than the title. If you close the front door of the house the
picture will jitter then settle...........maybe, then sometimes it will
jitter up and down, the top corners will jiggle in.. But never does it go black.
It is as though the picture looses configuration and then snaps back. Tap
on the side of the TV and most the time the jittery picture will react to the
tap. If left alone usually the picture will settle in to hours of operation
without any jitter. Sometimes jitter every now and then. When it is jittering if you lightly tap on
the bottom it is affected generally double as much as tapping the upper side. So
sometimes it jitters a couple times and stops, other times it jitters for
minutes and minutes and eventually stops.
When a friend plugged in his PS2-3 to the front input, the sound from guitar hero the picture was affected so much by the game noise that we had to patch the sound directly to the receiver and not use the TV speakers. Anyway it acts mainly as though it is a loose connection. When the TV is cold and turned on fresh it takes a while before it stops jittering and becomes stable.
Is this a connection and/or a component on a specific board that is known for doing this? I figure I can pull it out and solder it or replace the component fairly easily with some good instruction. I know nothing about that part, how it works etc. But if I can find the thing I can get it cut out and get a new one soldered in if it needs to be done. But I need some good and helpful direction.
So is there a place on a board that is known to cause this problem generally. Sure would be nice to find it before it goes completely and/or destroys something else while doing so, not to mention to watch a movie without the jitters would be nice too.... Sure appreciate your time and help. Thank you.. Stringpickin@comcast.net
sounds very much like a loose connection, i.e. a wire or solder joint, you could have a look around make sure everything is plugged in right, as for the solder joints id advise getting it proffessionally looked at as these rear projection tvs can be a lot of hassle if you slighty knock any of the 3 tubes,

Good Day, LDS also;
You may have a poor seated cable connector. Unplug TV from A/C, remove back look for a large black connector. It connects between the Main Digital Module and the Drive PWB. Re-insert both ends several times to make better contact, use contact cleaner if have but not always needed. Good Luck, big IRISH.

the three guns that the lenses drive operate at 28kv.
there are very high and dangerous voltages in a tv set.
you can look for the fuse main pc board by the power cord..if it is black,there is a major short.if it is just barely blown,change it.
the fuses are 3ag glass type and just pop in. use a set of rubber gloves and insulated pliers.. tvs are DANGEROUS
