Yellow and blue color ruins total picture on 50" tv,can't get rid


lupe0112,

I'm no expert, but I think that you have a problem with the convergence of the 3 color guns. I've been working on a similar problem. As a first step, have you tried "Magic Focus?" The Magic Focus button for the Hitachi 53UDX10B is at the left of the small front panel controls that also include your RCA composite and SVideo connectors. Let the set warm up for about 20 minutes (as recommended by the user guide), and then press the Magic Focus button. When you press the Magic focus button, the set will auto align the 3 color guns. If this doesn't fix your problem, unplug the TV for at least 4 hours and try again.

Magic focus --blue and yellow sag in the upper left area of the screen


This is a problem with the convergence circuit. If you can solder, you can repair this yourself. First try and resolder the pins on the existing convergence ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. If the resoldering does not resolve the problem, replace the ICs.

Convergence Problem


sounds like 1 of the convergence chips are gone theres 2 of them and better off replacing both as the other would just go a month down the line there might also be a resister or 2 gone, the price for that kind of job is around 150 +vat.

hope this helps

It's a hardware malfunction. It can't finish the magic focus cuz one of the IC is burned. Need to be replaced and to check the resistors.

Loss of color picture


I have a blue-ish yellow ghost tint which just appeared on my 51" 51SWX20B made July 2002. Did the magic focus got a number 5 at the end. Did you get a number when you did the magic focus?
