Are these faults acceptable?



I'd appreciate some advice regarding the response I've just had from the dealer I bought a Toshiba 36ZP18P from (the old model). The set has an annoying geometry problem in that the picture is not 'level' i.e. it is about 3 or 4° rotated. In addition, the screen had 3 large 'watermarks' which look like a magnetic effect; there is a large radiator near one side of the set but the effects appear at both sides and near the middle.

I called the dealer about this an was basically told that:

"Slight picture rotation is normal on large screen glass TV's due to the superflat configuration this should only be noticeable when viewed in incorrect format."


"The problem with the purity is also common to large tubes they should not be positioned anywhere near metal objects as the inherent magnetic fields will take effect, also any movement of the TV whilst on will cause purity 2 distraught. If the set is moved away from any metal objects and left off for an hour or two switching back on will correct any error."

Now, I'm pretty ignorant but I can't see how the rotation can be acceptable in a £1000+ TV. It looks appalling particularly when I'm looking at menus on DVDs. I know that some sets have geomagnetic correction but this one doesn't. Can in be sorted by altering the set geometry or should I stand my ground and insist on an engineer visit?

Regarding the second fault, I haven't had the opportunity to move the set (it weighs 71kg) but can't believe that a radiator on one side of the set can cause distortion on the opposite side of the screen too. Does it sound feasible or am I being fobbed off?

Any advice would be most welcome.

Every decent quality set of 32" or larger that I've seen has adjustable picture rotation. If not, the only option may be to manually adjust the scan coils, assuming they aren't bonded to the tube.

Large tubes are indeed more susceptable to purity errors than smaller tubes. I've seen several radiators that have been the cause of purity errors. One was even in the house next door. They can be demagnetised by the same degaussing coil than engineers usually use to degauss a tube after replacing it. This isn't always a permanent cure though as the Earth's magnetic field can induce very slight magnetism again.

Your TV does not have adjustable picture rotation, the engineer will manually adjust scan coils, as GaryB said.
On this model it requires a light tap with a hammer, some engineers are reluctant to do this, insist on a replacement if so.
The rotation varies, next TV may be a better sample ( or worse ).

How long have you had the tv for?

If you have only just got it, then I would ask for a refund as the 36ZP18 had a notorious reputation for problems, some of which were inherent in it's design and were impossible to rectify.


Thanks for the replies everyone, you 've confirmed my suspicions.
I'm concerned about the problems fatbob mentioned, though. Anything I should look out for in particular?
