Re: Hitachi TV Model 42EDT41 42 Inch

TCON failure

If those lines are completely thru top to bottom,you may have a defective plasma panel. That will not be feasable to repair

you'll need a new panel, or a new TV, sorry

This is a convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors.Shops usually charge from $200-$300

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.

On al the plasma tvs there are control boards on the lower part of the screen that control the vertical images. If one of the chips on one of the boards fail, have a bad connection, or no ground it will result in a thick black lne down the screen. Seeing as the tv is new I would get the warrantee repair on it. There is a possibility that there is a problem with the screen itself but more than likely its the boards.

same problem 2 inch vertical line in center of screen! could this be something loose in the back??

I want to know the possible cause of tv with 2 black line at the top and bottom of the screen. Is it have the same causes even if the tv model is not the same..thanks

did you fix the black line? please let me know as my TV (same model) has the same problem.

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 [email protected].
