Convergence is bad on left side...good on right.....where convergence is good the picture is great


Hi,
Re-solder convergence output ICs pins and nearby big resistors that might solve your tv picture problem and if that does not help then replace both convergence output ICs to fix the problem.
Convergence output ICs would be available in local repair parts shop or google it.
Thanks.

My Sony KP 51W520 won't come on. The standby light flashes 10 times. I read through the other people's problems listed here and everyone else has had either 3 blinks or 9. Any thoughts?


Hi.
it seems that your power supply or high voltage section is failing. Look for PWM IC genarator. MCZ 3001D on Power supply and near high voltage section. Try to replace these IC's.

I have Sony KP-46WT500 Projection TV. For some time it appears convergence went bad. I see multiple images, especially at edges and corners. As many as 3 images Red, Blue and Green. I am an Electronics...


Hi,
It would be great to assist you in Sony convergence issue.
As you said, for some time TV shows bad convergence in picture that shows its matter of lose/ dry solder joints in D board, specially on convergence out ICs pins that need to be re-solder.
There are 2 big black ICs mounted on aluminum heat sink on D Board of TV, below image shows D Board location in TV.
Resolder pins of these 2 ICs and also check any other dry/ cold solder joints in circuit board. I do not think of IC replacement as problem occurs some time.
Let me know if you have additional question.
Thanks.

I have a hitachi 50FX18B and the convergence lines are not lining up and the picture looks like you are looking through 3D glasses. How do I fix this??


This is a problem with the convergence circuit. If you can solder, you can fix this yourself. Please note as well that there are potentially dangerous high voltages present even when the set is unplugged. That being said... Open up the back and locate the convergence ICs (large black ICs attached to a heatsink and marked STKxxx). Try resoldering the pins on these ICs first. If that fails to resolve the problem, replace the ICs. There may be other related components that need to be replaced as well, but start with the ICs.

Keep us posted.

KP-61HS10 Convergence IC Replacement


yes they can hold a bit of voltage so a high voltage probe will discharge them nicely, something you might not have but can get from ebay if you are going to do this alot. you don't need to be concerned about this though as you won't be doing anything with them so don't touch..
just be carefull when desoldering these stk's use solder wick and patience even a pro can take an hour to desolder these so be carefull not to lift the trace or the situation will quickly get worse. don't adjust these tubes as they are set to the correct alignment already.

Sony KP 51WS510 convergence problem


Please check pico fuses in D board and confirm +22 & -22 volt supply to convergence ICs.
Fuse numbers are as follows...

PS8001, PS8002, PS8003, PS8004, PS8005, PS8006

Did you check the resitors out of circuit? As its very rare when a Hitachi doesnt open at least two on the affected circuit. If you checked the resistors in circuit an open resitor will read good even though its actually open.

The Convergence ICs will only distort the picture. Youre having deflection problems. I would check the horizontal and low voltage regulators.
