Four days ago, my TV montor went from a very clear picture to vertical lines completely across it. Now when I first turn my TV on, it has a clear picture for about 3 mins. then it gets vertical lines again. I can see about 5 pictures of each picture jumping within the sets of vertical lines. Can you provide me with a solution? Thanks!
Most likely you have broken solder joints in the vertical section of the mpc board. This is why it takes appx. 3 min before it seems to break down. Hair line solder cracks expand when they heat up.

You would only get one line if the horizontal sweep output is faulty. More likely the IC that outputs all this.

sounds like it may be a horizontal frequency, or sweep problem (resulting in vertical lines)
refer to this site also. they only supply parts to north america, but it's a good resource for information.

I've got a no vertical sweep problem on my JVC.
bought a 42" inch plasma, but want to fix the 29" inch JVC 'cause it's still a great TV.
I just need to source the parts.
Good Luck.
