Panasonic CT32XF37 out of focus
Hi all,
I got this 32" Panasonic Gaoo CT32XF37 TV. It is totally out of focus - the picture and the on-screen menu. Does anybody know where I can locate service manual for this TV? Search on Google and on a couple service manual websites did not yield anything. Thank you! viperz (at) mail (dot) com |

The service manual should normally be available from the Panasonic parts
department. This is not a free publication. As for the focus problem, this can most likely be in the HV multiplier, or the CRT is defective. It is possible however that the video amps are over biasing the CRT because of failed components, but this is not common. -- Jerry G. ========================== "Eugen T" wrote in message . ..

I thought about HV multiplier, that's why I need the schematics. I wasn't
looking for a free service manual, just need a link on where to get one. "Jerry G." wrote in message ... The service manual should normally be available from the Panasonic parts department.

Usually this is integral to the flyback transformer. A service manual probably won't be very useful for this fault, you'll need a HV probe (you can make a makeshift one without too much trouble) but otherwise it shouldn't be too hard to confirm the fault. |

What happens when you tweak the focus pot?
