    Colors ( green & red) are bowed at the bottom of the screen. Convergence doesn't resolve the issue.

    We have the same problem with green line bowed at the tope of the tv. My husband replace the green convergence chip and this did not fix the problem. Any suggestions for our next attempt?

Check its convergence adjustments. If convergence board have the fault, the vertical lines will be shown as bowed. Might need replacement. Just try to adjust the convergence first. If you wish to get more details about how to adjust this, check the site linked here. http://electronicshelponline.blogspot.com/

Tv turns on. There is a picture but it looks like your looking through a fish bowl. Bowes into the middle from both sides. It also looks 3D. Any Clue??


This is usually a convergence problem, although the bowing normally is from the top and bottom rather than from the sides. There may also be an issue with the pioncushion circuit that causes the bowing. Try the automatic convergence adjustment first. If that fails to resolve the problem, then resoldering the convergence ICs would be next followed by replacing the ICs should the resoldering fail.

If you wish to attempt the repair, please update this and confirm the model number to be VS-60607 and I'll provide additional details.

Thanks,

Hello,
You are experiencing a lack of vertical deflection or vertical collapse. Since it will come back the first thing I would suspect is “ring cracks” in the solder joint in the vertical circuit, mainly the vertical IC. These suspect solder joint can be re-soldered and the television set repaired.
I would suggest that you contact a local servicer. If you are repairing the set yourself, be careful, there is always a risk of shock when dealing with electronics.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Bowing picture


If it is no longer under warranty, locate the convergence ICs which will be large black ICs attacked to a heatsink. Try resoldering the pins on these ICs first. If that does not resolve the problem, replace the ICs. These should be marked STKxxx.

Keep me posted,

Picture is blurry and is shaped like a bow tie on my tv


This is a convergence problem that you can fix if you can solder. Let me know if you wish to attempt the repair and I'll post additional details and instructions.

Horizontal line across my tv


This is a problem with the vertical circuit and is relatively common. If you can solder you can fix this yourself. First try resoldering the pins on the vertical IC. If that fails to resolve the problem, replace the IC. This IC is a small flat IC attached to a heatsink having about 11 pins or so. Is will be marked LA7837 or something similar. Post the marking here and I'll confirm the part.

Keep us posted.

The problem here is that the vertical IC either has bad connections or is defective. Look for a small flat IC with about 11 pins attached to a heat sink. It will be marked LA7837 or something similar. Try resoldering the pins on the IC first. If that fails to resolve the problem replace the IC.
