Question about Televison & Video
you need to check your + and - 15 volt lines, sounds like you have bad convergence IC`s and at least one open or way up in value resistor in the convergence section.

This may not be the problem but its worth a try:
The plasma display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. May have to go inside and see if the contact assembly is disturbed or warped or something.

it looks like theres a wave in the top of my screen on my jvc av-48wp30 not sure but i think it has something to do with the bulbs because the projection mirror wasfine and all wires seemed to be hooked up properly.. can you help? tell me where i can find the bulbs to replace them?

the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.

you are in luck my friend! i just performed a fix on a gateway plasma that has LG boards inside. It is exactly what you are talking about. Go to the attached link and follow the thread carefully and read it all before starting. IT WILL WORK!
