Color is fading and there's a red trail even though the convergence has been repaired.

If your model is 43UWX10B you need two STK392-110 Convergence ICs. and one each of the following 1watt reseistors. 3.3 ohm, 1.8 ohm, 2.7 ohm, 1.5 ohm, 3.9 ohm, and 2.2 ohm they are in order RK42, 46, 50, 54, 58 and RK60.
You can get replacement ICs and resistors at the following link and they provide free instalation instructions.

SOURCE: Can not align red even though convergence board WS-55819

Did you replace the center board with the STK-392-570 chips or the Digital convergence board mounted on it?


98% of the time if you have a convergence problem it is on the center board---the small board on the left under the metal shield box stores and controls the convergence of this set.


WHICH DID YOU REPLACE?

I am here to help----I have fixed hundreds of Mitsubishi sets with convergence troubles.

Hi,
If the green color can't be align anymore in the convergence alignment through the menu, this is an indication of faulty convergence board inside. Your unit used STK-392-110 as convergence chip(IC) mounted in the heat sink. Replaced this IC and some of the resistors around to have a best picture again. You may do-it-yourself if you have a knowledge in soldering and disoldering technique. Just prepare some tools and I will give you the link to order online for convergence repair kit to save some hundreds of dollar for service fee alone.

But before you make an order for parts, check first the board for bad solder joints(cracked/dried/cold solder) because it will do the same symptoms. Re-solder as much as possible.
If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to look for a qualified tv technician to do the job for you.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
