Question about Televison & Video

We have an older 3 year 42" Hitachi Plasma TV. There is a black line about 2" wide running down the screen from top to bottom slightly off center. Sometimes it goes away and sometimes it doesn't.

You may have bad connections inside the TV. Either loos cables (flat cables) or loose IC that needs soldering.

You may want to check videos below on TV repairs. I cannot find a Hitachi but the approach is almost the same. I would advice caution if ever you want to try it out.

Plasma color TV screen developed dense black vertical line


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. Vitally

Black line on plasma tv


hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works

Black line in center of screen


These black lines on the plasma screens are very fixable.  There is a dry solder joint on a circuit board at the bottom of the plasma that needs resoldered.  There are 6 or 7 "ribbons" along the bottom of the screen that correspond to vertical sections of the display, so you just follow the black vertical line down to figure out which one is faulty.  I just performed this fix successfully on my first attempt on a Gateway plasma, but it will work on most plasma's, specifically Hitachi, gateway, LG, Hyundai, & Akai. I think they may all have LG boards, my gateway did.
I can't really describe very well what to do, but I assure you it is fixable.  If anyone is near nashville, I might be able to help you out.  My email is tomp2000@juno.com.
thanks,
ST
