Try setting a portable fan aimed toward the cooling vents on the back of the set. If this eliminates or reduces the occurance of the lines, this means a circuit that controls the off/on of individual pixels has developed a thermal problem. This circuit is ordinarily loacted on the main circuit board and is likely to degrade further. You might inquire at the Panasonic service center if they have an exchange program in place and they will probably be able to confirm my suspicions.

Bad filters on one of the video processing boards. you will need to have a shop do this repair, expect to pay around $250- $300.

SOURCE: Why would there vertical lines on my toshiba theater wide tv?

this sounds like a bad capacitor. If you want to fix it yourself and know how to solder on a pcb, then replace all of the electrolytic capacitors.

TV is older and has had a great picture through the years. It has now developed blue vertical lines all the way across the screen every 3/4".


Those are retrace lines from too bright a picture. If you can't get them to go away with the brightness control then a repair is necessary

Projection TV no picture flashing horiz arcs across top of screen sound okay


You will need convergence work to this unit. Not cheap.(Not recommended for DIY unless already experienced in this type work). Might contact a local servicer experienced with Toshiba & see if they can give you a quote over the phone. Be sure you are sitting.
This is probably a good time to consider entering the 21st century & look at LCD or LED flat screens.

Got the TV 4 free so lets start at that. Was a very poor picture so checked the guns saw the green/blue was very foggy and changed the CRT Fluid in Green and blue red obviously was fine. Now tv up and...


are the lines slightly curved and go from the botom to top across the screen. If so it sounds like retrace lines from the CRTs being turned up too far. You can add the pic by clicking the camera Icon next to where it says Insert below the text box.

JVC TV 27" Black line on top of screen


This is for the original problem.. Not the second post.

It's a problem in the horizontal deflection circuit. The parts will be available, but you will be in for some daignostic repairs also to find out why it failing or if it has failed on it's own.
There should be a few caps near the IC (an LA7840) that could also be causing the problem. Click the link, it will make it easier to locate the part inside.

This is the kind of repair best left to a TV tech, but get it done now and it won't cost anywhere near as much as it will later.
