it even happens like this when using the built in tuner, so it's not
the source. it's a C28W440 (I'm pretty sure, I'm away from home, but googling would suggest that this is what I have - it looks like it) Thanks for your post. |

Advise welcome. you have a problem in the E-W pincushion circuit. probably an open resistor. If not experienced in TV repair.... Get it to a tech! Ben |

Agreed, also a fair amount of keystone distortion, probably due the defects
in the same curciut area.

Thanks for the help. I have a slight background in Electronics, so I
think I might have a crack at this myself. I would rather blow up a =A3250 TV and buy a new one, then pay =A3150 to get it fixed.... the =A3100 price difference is worth the risk IMO. Can anyone suggest a place I could get a service manual for this TV, either in PDF or a hard copy? Many Thanks, Ian |

From their site:
'Generally speaking ESTA is only available to authorised service shops and is issued under the control of each local Hitachi sales office.'. I've looked on google to try to find places selling manuals, however haven't had much luck. I've sent an email to hitachi but I'm not holding my breath for that to result in anything useful. Any other suggestions? |
