How do I replace convergence chips in a Mitsubishi ws-55311?

When it shuts down have you tried accessing the self diagnosis feature to retreve the error code?If so whats the blink code your getting?

The convergence IC chip or chips need to be replaced. Sometimes you can find them on Ebay pretty cheep. Sometimes just buying a used working board is less of a hassle. These chips will have a number like ST 393570 (Just an example). And they would be almost the length of your thumb. It will work but keep in mind soldering can be tough if you heat these up too much in the process of soldering? They will fry.

This tv have a problems known as a conveegence problems,it dead.The tv convergence board must have it 2 STK convergence ICS and some or all it resistors to be replaced to solved the convergence problems.The shop will cost u $300-350 for parts and labors.

Try website like Tvrepairworld.com to buy a refurbish DM power board for the replacement or parts.U know soldering?Buy capacitors for repalcement.

This is a common problem. Its called a convergence failure.

Problem #1) Convergence

Symptoms:

• Screen Looks 3D
• Colors wont align
• Video may look distorted

Replace Both of your convergence ICs example STK392-570 they are big black ICs Call Mats 1-800-628-1118

These sets use pico fuses ---a 2-2 code usually means one of the convergence chips is shorted and has taken one or both pico fuses out that protect the chips--set detects no voltage and shuts set down instantly--this model uses 2 STK-394-250 CHIPS---I can send you a photo of what the fuses look like--if you find either or both bad--you need to replace the chips--if you just replace the fuse(s) it will just do more damage.

They are not glass fuses--the set you have is a V22 chassis and the chips are location numbers: IC8C01 AND IC8CO2.

You might have a bad power supply or convergence circuit, I also suggest you to check for fluid spill on the circuit board. if the convergence is defective one of the 5A picofues on the power supply is open. Hope this help you.
