Re: Hitachi TV CMPAS14V
If you solder alot and work on small stuff ALL The time, then maybe you could resolder the ribbon cable resistors yourself. However if you get it too hot, or you don't know how to release the edge connectors, you WILL do more damage than good. You can very easily srew-up the ribbon cable then you have to replace the disply panel. I'd leave that to a professional. You must also remove boards and other parts to even get to the ribbon cables. Most do it your self tech's end up bringing in a T.V. that so butchered, I or no-one else will touch it. So keep that in mind.

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
My Hitachi TV Flat screen 42 EDT 4 1A has a one inch black line from the top to the bottom of the
screen on the left side. What or how do I fix it. I did blow it out with a air compressor as suggested by a local repairman.
anyone experiencing this problem should get in touch with Dave at email@example.com . he sold me a fix for this problem, for much less than the $400-$500 we were told it would cost to fix it. Dave not only solved the problem but provided the best customer service and support I have ever received. ABSOLUTLY the best money I ever spent, saved my T.V. Get in touch with the confidence of knowing he will help you as he did me. Thanks again Dave!!!
The matrix controler or the matrix drive area is failing. The fix is to change the proper circuit boards, and then do the factory setup to match the board is necessary. In the worse case, it may be the display screen itself that has a failure occuring.
You will have to bring the set for factory service to have the work done. If the set is out of warranty, it may be expensive to service.
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 firstname.lastname@example.org.
