SOURCE: 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.

SOURCE: sony bravia kdl 32l4000 - color bars running vertically on screen

In most cases is the screen is covered with vertical lines all the way accross the screen then the T-Con module is at fault. The t-con board is replaceable without having to replace the entire LCD panel which would usually make it cheaper than replacing the TV. The part number I come up with is 1-857-213-11. Please take a moment to rate my answer. Thanks...

SOURCE: 40xbr2 bravia kdl sony LCD tv. The screen shuts

Problems relating to the automatic turn on and turn off of a set like this usually point to the main board being an issue. For this set, I believe Sony refers to that board as the "AU" board.

It's probably not the G/Power Supply board, especially if it turns itself on. Power supplies will turn a set off, but rarely--rarely--turn itself on.

If there's no kind of extended warranty involved here,
you could be looking at $500.00 for parts and labor to repair this kind of problem.

As always, try any software/firmware updates Sony might have available on their website prior to pursuing a repair visit.

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

Continuous vertical roll on tv


Wow 5 months without a solution. NOT GOOD.. Well I hope I can help...
This sounds like a vertical hold problem, and is normally easy to fix.... There should be a couple of nob's on the lower back of the TV. One for vertical and one for Horizontal hold. You need to find the vertical hold nob and adjust it, until the rolling stops and stabilizes. If however these nob's are not visible you will have to take TV to an engineer to fix it.
Hope this helps..

The picture on my TS-4573 rear projection tv has started to roll vertically at a fast rate. How can I make this stop. On old tv's there was a vertical hold adjustment on the back that you could play with...


this fault is caused by defective electrolytic capacitors in the vertical deflection circuits, they need to be changed out, do this before it causes more problems, there are no adjustments for this anymore.

Vertical line at edge of AV1 channel


hi! he might have adjusted the vertical hold and height including the linearity. normally on the board you would see a trimmer resistor with a label v-hold this is to stop the rolling, v- height for the size of the picture. and linearity for the evenness of the picture from top to bottom.

Rolling screen


Does the onscreen menu roll too? If so, vertical hold needs to be adjusted. Not sure if on this model if that's in the service menu or a manual adjustment on the motherboard. Keep searching google and see if anyone else has had that issue too. 
Good Luck!

Rolling screen


This may be a vertical hold control problem I'm not sure where the Vert. Hold potentiometer is on the mainboard. I would see if you can find someone who can locate it and adjust it.
