Question about Zenith R57W46 57" Rear Projection Television
You can get the convergence repair kit to repair that problem at this link. The kit contains both ICs and the feed resistors, and also has instructions so you can do the repair yourself.

The convergence IC's need to be replaced. look for stk letters and some numbers on them. If You are familiar with electronics repair try replacing them but be careful there is high voltage in the set even after unpluging it from the wall. Post back

This is a set first made in 2001---if colors are skewed and will not adjust in the customer mode (convergence) you have a convergence circuit problem.
This set uses two of the STK-392-150 convergence IC chips--both need to be replaced and the set adjusted. Sometimes there will be either a fuse or resistor around them that is bad--for the most part just both chips need to be replaced.
Most shops get 300 or more for this repair but you can buy a pair of chips on EBAY for under 14 dollars plus shipping.
If you or someone you know can do it I can tell you everything you will need to do it and give general instructions on how to get at the chips and replace them.
Here is a picture of a similar model with the same problem:
Not all sets with this problem look exactly the same.
This photo was provided to me by a customer who I repaired the set for and shows a typical convergence problem in this type of TV.

If you want to know where to get the parts and also what is needed for the repair---let me know and I will post the needed items first and the instructions also.
