I am getting a blackline that runs vertically in the middle of my screen. It is a 42" plasma superscan tv. The line pops up for a couple of minutes then goes away. It comes up a couple of minutes after the tv has been turned on
Hopefully you still have under warrantee. If not, sorry. This line if memory serves me right is because the tv has 2 picture panels on each side of the TV (they join up together to make one picture). Toshiba did not realize that the panels will start slipping thus creating this fine line from the top of the screen to the bottom. They have revamped the newer models and placed glass to adhere the panels together. Even though my TV was under warrantee I got a new one and have had this one for 1/2 year and now the picture just blew (there is sound but no picture.) Take your TV back if it is under warrantee.

Hi I have a LG RZ42px11 there are 6 vertical thick black lines running down the middle off the screen, when cold the TV seems OK but if it has been on for around 10mins or on standby the lines stay on screen.
There are two boards at the bottom of the set connected to the panel. Follow the black line to the boards(it will be inline with one or the other) either that board is bad or the panel itself is bad . The boards do not meet exactly in the middle.
This is the best solution for your problem as a 40 year experience with wires etc.
Go to the source of your cable signal connector .
Open it and clean the terminals with emery paper , sand the end of the cable shiny clean from corrosion , get a new barrel connectors with gold terminals if possible lengthen the ends of the cable , insert and tighten good, use thick rg-16 or rg 40 cable with good insulation ends crimped professionally with a crimpier or buy ready made , not from dollar store. Get a gold plated professional splitter if you need one or two , it will cost about 15 or more each . Make the cable runs as short as possible, using the thick good cables. If needed get a signal magnifier. From radio shack or the source etc. Connect them good and tight . Ground the splitters . Problem solved , you will get crystal clear channel 2 to 7 including 3 and 4 . Isolate the TV cable from other cables and power wires.
It sounds like an Intergrated Circuit (IC) has fried. Even on a good day, this is not something you can attack at home. As a tech (and as an owner of that model samsung), I'd need a map & tools to know what's going on. Your best bet in this situation is to contact Samsung and let them recommend an authorized service center in your area. Sorry I can't be of more help, but this is a rather serious problem.
If the set is still in warranty, call for warranty service. If not and you feel comfortable working on the set, carefully open up the back and reseat all of hte cables and connectors. This can be caused by marginal connections inside the set.
here is one thing it could be cracked solder on the ribbon cables going to the screen there along the bottom of the TV if the bars line up with a connector it is probably your problem i will try to post the link to a hole writeup on it
