Question about Hitachi 43FDX01B TV

1 Answer

Digital Array? My Hitachi 50GX30B rear projection Tv has a blue line that runs from the top right corner to the top left corner and goes down about a 3rd of the way of the screen, looking like a smile on the tv. The digital array will not converge and line up the blue color. Any help appreciated. Cannot adjust digital array. Blue is way out of whack

Re: Digital Array?

Replace IK04 and IK05, both STK392-110, but use instead STK392-150's for greater reliability. And don't get some Chineese knock-offs - use original Sanyo replacements. If you don't know where to get those try ACME Enterprises in Florida,
Also measure the low ohm feed resistors in that circuit. However usually just replacing the convergence amps will restore normal video...

i am not sure these is going to work but give it a try. after useing the tv for a long time you can get a problem with the lineing of the three picture colors may drift away from each other causeing the problem you have, they move because of moveing the tv or the viberation of the tv.  you can to one of two things if you have a remote for the tv go to the menu and look for the convergence adj. setting then you are going to get close to you tv and press the small but the says the same thing now on the screen you are going to see a grid the you can fix youself with the remote just by pressing the up, down,left, rigth buttons and the menu button to change the color, to aline the red line and blue line with the middle line till you get only a white line going up and down  if the doesn't work just unplugg th power cord and what for about 4 hours and then plug it in and turn it on again. if after you do all these if you still have the problem then you either have two choices call to see how much it will cost to repair it or toss it out and get a new one

Top left corner double picture red and green

you have a failed IC resistor usually you can physically see the bad one because it burns out leaving you to guess what the value was. Hitachi offers a convergence fix kit which has 2 IC's and all approiate resistors.
