Resistirs are designed to protect the circuits on the PCB. This is designed to allow a much cheaper part to burnout before the more expensive circuitry burns.

    Sorry, it is spelled resistors.

On the screen there is a green shadow on one side and a red shadow on the other side of every object in the scene


Hi,
This tv has two big black ICs as convergence output on deflection circuit board that are defective and causing problem in tv, IC number is STK392-110
replace both ICs to solve tv problem, also chekc for faded color big resistor nearby these ICs or those got burn mark, replace these resistors with same value, aslo check cold/ dry solder joints in deflection circuit board and resolder these joint/ connections.
Thanks.

Television has double images like 3D, and bottom half of screen has a concaved image.


Hi,
Please replace convergence ICs in tv, there are two big black ICs that has number STK392-110 mounted with big aluminum heat sink, replacement these ICs will solve your tv problem. Also check big resistor nearby these convergence ICs and replace if found burn mark or color faded.
On circuit board, IC location number is IC7001 and IC7002
Let me know if you have additional question.
Thanks.

I am not able to use the blue and red convergence feature on my Akai Projection Television. Is there a solution to this problem? Thank you


Yes,convergence is dead ics and resister must be replace.U know how to solder right?Tries websites for convergence kit.Tv Repair World.com or Ebay.com.

Two picters, round on top and round on bottom


You are right. Check the convergence ICs and resistors.i don't know the resistance values . But that seems to happen a lot with Projection TVs

Convergence


This is a problem with the convergence circuit. If you can solder, you can fix this yourself. First try resoldering the pins on the convergence ICs. If that fails to resolve the problem, replace the ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. FIgure on $25 each for the ICs.

Samsung HCL5515WX/XAA convergence Issue


I would replace both of the STK392-040, and check the resistors with one side out of circuit. The variable resistors are melted at the factory after the resistance is dialed in. I would check the resistance on it before replacing it. You can get replacement ICs and resistors at the following link and they provide free instalation instructions.

Covergance problem.


Hello kidfarm,

Yes it is a good chance these two amplifiers are bad, since the convergence amps are usually connected as pairs.

red red green green blue blue
AMP1 AMP2

and I'll even venture to say that the resistors go to your green amplifier pair so in that case both AMPs (IC8D01 and IC8D02) should be changed out.

Manual convergence -service mode


you have some resistors that are still open . If the ICs go a resistor or two usually go open and you cant always tell unless you remove 1 leg out of circuit and check that the resistance is within 5% of the rated resistance. Trying to adjust it by the service menu will only place extra strain on the new ICs and they will blow on you. The resistors are located right next to the ICs there are about 8 of them all I dentical. Very easy to spot.

The actual Convergence amp ICs not located on the convergence board are probaly what killed the origional convergence module, and likewise has killed the new board. You will need to change the convergence ICs first then replace the convergence module.
I would recommend getting the service manual . I can post a link if you would like.

Only use the same part number when replacing convergence amps, or you will need to replace all of the power resistors with recommended values for the convergence amps subsituted.
