White band from top yo bottom of screen


Good luck with this. If it is under warranty, Sharp will take forever to do anything about it. I had this issue and Sharp wanted pictures of the problem, Pictures of the serial and model number and the receipt. I sent it to them 6 months ago and never heard anything back. If it is not under warranty, this is a major repair and it may cost more than a new television.

You will need to replace your two convergence I.C.s.They are two large IC mounted on a large aluminum heat sink.Replace both,look for any burned resistors near them,replace those if needed,and readjust your convergence. Good Luck

Let me know if you need any further help

If bowed like )( it is in the pincussion circuit or a wave moves up from bottom to top in what you have it is a bad input filter in the power supply. The wave if there will look like a ripple moving either up or down in what can be seen on the screen.

I have a Panasonic Quintrix F TV. About 6 weeks ago the tv screen started displaying


Rule out the signal source by seeing if same issue when a DVD etc is used.

Usually a wave like motion from bottom to top is either signal related or a problem in the power supply (wave moves from bottom to top suggests that).

If not on rear inputs (A/V) it is not the power supply.

Model number is not indicated here and might be helpful.

I have waves running up my screen how do i fix that


hi
depending on the waves if it is light dark bar rolling from bottom to top it may be a defective
capacitor in IF section or interference comming
for ex:defective neon sign leaky electric power transformer etc. If it is a slow moving
wave but no bars you have a defective power suply regulator and I don't suggest you try to fix it yourself
