32ZP48 Geometry problems..

When i bring up the sky browse menu at the bottom of the screen,the sides are 'zig zagged' and not straight,i reduced the format to 4:3 and noticed that the edges of the screen were 'wonky'.

Whenever straight lines are on a dvd or tv program,i can notice it.

I called sound and vision uk were i got the set and they basically said that its skys broadcast that is causing the menu bar to be wonky and not the set?? However,the toshiba customer services dude said that he has the set and the sky menu bar is perfectly straight?

Am i being fobbed off here? Can someone else who has the set confirm that the sky menu bar should be dead straight?

Sound and vision said if they send out a technician and it turns out to be not a fault of the set then i would have to pay for charges etc

Im at a loss now.....


Heres how it looks:

can you please try reducing the contrast when displaying the menu bar. As this is very bright it may well be a power supply problem. So put the contrast of the sky box on low tv on low and bring the EPG up. Let me know how you get on

Reducing the contrast made no difference at all

I have emailed a fault form to sound and vision,only thing is,if the tech guy says its within the manufacturers guidlines,i will have to cough up £15 adminastration fee for sound and vision..PLUS the callout charge and time of the technician

Im nervous.

If no change with contrast then it is not anything to do with the power supply on the TV. What you described was a classic symptom of in-adequate PS for a CRT based set. I know for certain that on Sony TV's you have an adjustment called top & bottom trapezoid that may help for this type of distortion. Cant remember on a Toshiba

Beware, you can make things worse in the service menu. Write your settings down first before you play.

It's clearly the set. Either get into service menu and try to sort it with DVE as a reference tool or make sure you get an engineer out and accept no tosh(ing) rubbish

Only one thing I can possibly think of before making any drastic adjustments is to make sure you have no magnetic objects like speakers or transformers that can create a magnetic field to near. This is I would make your first port of call before going further.

As previous poster said a copy of DVE will help you a lot. There is a link to get a couple of quid off it somewhere, I used it for mine but that was a couple of months ago. Search the forums for blah dve.

Well i have the DVE dvd and have used it already,my settings and picture quality are great,its just the wonky sides

Service menu doesnt help as the 32" doesnt have geometry options like the 36" does.Adjusting picture settings doesnt change diddly.

Yes but you access the settings in the same way. The settings suggested there are for a picture frame 2 model, and each model will be different. With a test card (there is a built in one) you can adjust the geometry settings.

Well DVE should tell you whether you have straight sides in 14:9 and 4:3 modes.
The 1:33 overscan grid is good for this and adjusting the overscan incorrectly can cause all kinds of wobbly lines.

There must be some settings for side adjustment or the TV would not be vertically straight at all. Whether this is achieved via access to another menu or adjusted the old fashion way via the deflection coils direct from the factory set-up line.

FWIW I saw a ZP48 Tosh instore with a bow outwards at the top right hand side when in 4:3 mode.

The setting available on the 36 only in the feature mode is for a tilt adjustment. The service menu is accessed differently. It is designed for engineers and those confident to make those adjustments.
A crt will never be perfect.

Per-sony-fied,they all seem have geometry issues which with time and effort can be sorted.It does show that Toshiba's qc dept don't seem to care what they send out. Other manufacturers standards for geometry are far better.

You need Chapter 12, Title 17,18,19 and 20 also chapter 15 title 2 and 3 would be useful.
