Sounds like a pincushion problem. There is a knob or setting you can adjust for this problem. More then likely, a resistor has burnt out near the pincushion control, and trying to adjust it will not help very much.

I have an older JVC projection tv (50") the only


Problem is what is called "Convergence" and most of these sets like the model indicated use two STK-329-110 IC chips for this.

See attached photos of the board in this set and the black chips. This is a fairly easy set to get at them and I can tell you how. This does involve soldering, each chip has 18 pins. There are also some resistors in front of them that need to be inspected.

Total parts cost on EBAY would be well under 25 dollars and repair takes less than one hour.

Look the the attached photos and tell me if you think you or someone you know could do the repair if I tell what is needed, and how to get at them.

Picture looks like hour glass.


You're probably talking about bad convergence. Probably Convergence power board. Only $20-$30 from encompassparts. com, if still available.

Hi,
This kind of picture problem is due to failure of convergence out ICs, please replace convergence out ICs in tv to get it fixed.
If you are handy with electronics stuff repair and can replace parts in circuit board with proper tools then can replace above said ICs by yourself or ask local tv tech to repair your tv.
Thanks.

Your convergence IC's are bad. If your not doing the work it will probably cost in the neighbor hood of $250.00 for a service company to do. Not a major repair.

The convergence circuit needs repaired. I did the same job yesterday on this model. I not only replaced the convergence ICs, but, I had to replace a couple of resistors and a coil. The convergence alignment was minor after that.

Red and Blue shadowing (Where are my 3d glasses)


There are two convergence IC's that are bad and need to be replaced, as this happens to almost every rear projectionj set ever made. They are stand up IC's , on a heatsink and they start with STK. They are soldered into place and this set has no user replaceable parts inside of it. If you have no solid state repair experience, you really should call out a trained tech to assist you in this repair. A TV set is no place to be diggin and experimenting inside of.
