I have a Sony KP53V45 projection television. I have a problem where the
screen is full of horizontal lines. One repair shop told me it was probably
the chip that controls convergence and want $400.00 to fix it. Is this
possible? Can I replace the chip myself, and if so, how do I know which
chip it is? I'm pretty handy with a soldering iron.

Thanks, Steve

I have not worked on the specific model you have, but have serviced
many of the other types.

Generaly speaking, the fault is most likely more than a simple chip.
These kits usualy comprise of a fair number of components. After
installation the proper evalution must be made, and there are usually
some calibrations to be done.

The price you were quoted is a fair price for a repair that can take a
few hours to perform. Also, many of the kits are not cheap to buy.

Actually Jerry, if it is a convergence problem, it is most likely either a
bad solder joint or a bad output IC and likely nothing else unless the
convergence generator is bad. the latter would be very rare. Problem is,
someone who does not have the experience and the documentation is unlikely
to figure out what it is. You could take a shot at changing the convergence
output and resoldering a buch of joints and maybe fix it, but the problem
might be unrelated to convergence at all with such a vague symptom.

Who uses kits to fix convergence problems anyway?

Hitachi has a Kit for certain Models for Convergence trouble.

Yes they do, but they are not a lot of components. In most cases they are
not even needed. I fix several Hitachi convergeence problems a week and
never order anything but the chips and just keep an assortment of resistors.
In general, kits are rarely used for convergence repairs and on the Sony set
discussed, I have never seen a kit even marketed.

The point is that Jerry's advice was, as usual, not very accurate for the
specific product (not even for the product category) mentioned and of little
help to the OP. The OP needs to be more descriptive of the problem and if
it is convergence, he can probably fix it with a little soldering, possibly
a chip, and possibly a fuse. The related parts need to be checked but in
these sets it is rare for anything else to be a problem in the convergence
output stage.

I have seen horizontal lines and other weird defects on Sony

projectors caused by the jungle chip. Chuck
