You need to replace the STK ICs which are Convergence ICs STK392-110 use 120s or 150s

WT-46807 Red convergence is distorted, in an arch at the bottom.


Yes your model is the V17 chassis mitsubishi. The Convergence Ics are located on the center board. you will need two STK392-570 convergence ICs. You can get replacement ICs at the following link and they provide free installation instructions. They are located on the backside of the wide heat sink with the fins on it on the center board

My Hitachi projection TV needs convergence amps. what are convergence amps?


The convergence amps are usually located on the extreme right side of the chassis looking in from the rear of the set. Located on a large heat sink. If you respond to this post with your correct model number I will post the correct ICs for your model, and you will need to replace the six convergence resistors as well.

Convergence ICs - Toshiba 57h81


they send the instalation instructions with the ICs , which tells you what tools you would need and exactly how to replace them. yes both Ics should be repalced together as they work together to control the 3rd color. yes STK392-110 are the correct ICs for your model.

Convergence


Hi there, this seems to be a classic case of bad or broken connections in the convergence circuit. there are a couple [2] convergence output ics on large heatsinks near the center of the main chassis, usually soldering the connections fixes this, but due to the nature of the make-and-break of the connections the ics may have been damaged so i usually replace them to avoid a call-back, generic numbers are usually STK391-110 for standard definition and STK391-570 for high definition. The actual part numbers and locations may vary from model to model and year to year, but these are the most common. good luck and be safe.

Mitsubishi vs50805


That is the classic symptom when your convergence ICs go out. They usually take out the two resistors that drive the ICs as well. This is a easy fix if you can solder. Your ICs are located on a large heat sink on the left side of the chassis they will have an STK392-110 number or similar number. They cost about 10.00 each. Let me know if I can assist you with any other info.
