Hello,

I have a Philips model 35P550 C101 TV and I believe the vertical sweep
chip is out. I do not have a lot of test equipment.. a multimeter is
really the only test gear that I have. The TV was given to me so if I
fry it I'm not too worried about it it will have been a good learning
experiecnces (I have taken all the necessary precautions not to fry
myself). My first question is how do I locate the Vertical IC? If I
locate and replace the IC what are the chacnes that is the only problem
or is there a good chance more components will need replaced? It's an
older but nice TV

here is are a few picture of the main board if that helps

Thanks in advance for any guidance you can give me.

Probably going to be more than just the vertical output. Follow the yoke
leads back to the main board, one pair go directly to the horiz deflection
the other pair to the vertical deflection.

What is the symptom that makes you believe the vertical sweep is out?

There is a horizontal white line in the center of the screen. The guy
who gave me the TV originally took it in for repair and was given that
diagnosis but then decied to buy a new TV.

I don't know your particular model, but can you post the part numbers
of likely ICs? Look for an IC on a heatsink, probably in a SIP. It
should be located near the yoke connector(s). Check the supply to this
IC. It will probably come from a winding on the flyback transformer
via a fusible resistor. Replace the electrolytic capacitors in the
vicinity of this IC, and also replace the smaller caps in the main
power supply as a precaution.

And when you find it, check any fusible resistors in the area, one or more
of them will usually open up when the chip fails..
