Picture is jumping lg55lb7500 - Televison & Video

Vertical jumping may have a vertical hold issue, horizontal may have a horizontal hold issue. Most older tv sets will have some knobs or adjustable screws for vertical and horizontal hold. Turn your set on and check for these knobs on the back of your set and adjust until your picture is in as well as you can get it

Check for a stuck button on the remote.

It is EMI ... electromagnetic interference...

Do you carry your cellphone when this happens? Maybe your iPod?... could also be static charge on your clothes (not likely, but possible)... like wearing sox on a carpet...

Please comment for further help...

Have you tried to hook it up on video instead of the coax cable

Sounds like a vertical sync issue on the chassis board. However you also mentioned the picture moves left to right or vice versa which would suggest a horizontal sync issue. Either issue is not repairable by the DIY. Sync issues must be isolated using test equipment usually found in repair shops. My suggestion push it down a hill and enjoy the show then go buy that flat screen you almost purchased last week.

Hi
Replied you on premium post as well.
Please change TV color system to AUTO to see jumping free picture.
If Bose is either on PAL or NTSC color system, TV will show correct picture and color automatically.

If this jumping is accompanied by a sharp snapping sound, it may be the high voltage circuit discharging to chassis. Leakage can cause the jumping and a discharge can momentarily blank the picture.

If you want to try a 'cleaning cure,' I suggest you pull the plug (not just turn it off) for several hours, preferably overnight. Sets of this size can carry enough static charge to punch a hole through your thumb if you get careless.
Remove the rear housing (shouldn't be more than 6-8 screws) and using a clean paintbrush, and possibly a vacuum to **** up the dust, clean it well and pay special attention to the area around a largish misshapen black plastic object bigger than most anything else and connected to the back of the picture tube via a fairly thick cable.     

Good Day;

Sounds like you may have a bad Format Board.

Good Luck, big IRISH.

Resolder the vertical output IC and the vertical yoke connections on the main PCB
