Ii have a old panasonic tv n the screen keeps jumping. How can I stop this?


Hello
The fault [vertical rolling, jumping] will be due to some value detereated electrolytic capacitors at the vertical output section of your tV. Repalce all the eelctrolytic capacitors [5 or 6 of them], on the vertcical output section on the main board.

I cant stop the tv monitor screen from jumping it has something with the dvr


Hello What type of TV do you have, analog or digital? If you have an analog TV and the screen is rolling it is the vertical hold. Because the vertical hold operate on 60 cycle which the same as AC line cycle. The 60 cycle in the vertical hold is as a oscillator or timing circuit. When the TV pick up the image for the NV devise, they just don't mix. Why, because image intensifier tube in the NV devise is operation at 25 to 50K Hz or cycles. The vertical hold circuit pick up on the 50K Hz signal which mixes with 60 cycle timing circuit causing the screen to rolling with lines across the screen @ 60 cycles. Digital camera and digital camcorder with digital TV will help, or a image inverter that takes this 50k Hz signal and covert it to some that analog TVs can use. GB...stewbison

Jumping horizontal lines when connected to CD player


Hello, I want you to do a test first. Take you TV and connect a DVD player to it and see if this problem occurs. I bet you it wont, because the problem is not with the TV nor the CD of the karaoke machine. The problem is with the sync pulses of the signal from the karaoky, and the inability of the Tv to sync-up with those signals. What I would use is a video stabilizer between the TV and the DVD player. If the TV still has the problem with the DVD player I would then check the TV for a vertical section problem. I hope this helps, Thank you, Shuttle83 http://www.electron-age-technologies-llc.com

Video tapes played through VCR experience vertical 'rolling'


unfortunatly no. the vert hold is set by black bars at the top/bottom of the video signal (outside of the viewable area). it sounds like your VCR or tape is damaged.
