It worked for my 28N03B set.

No, that didnt work either, any other ideas?

Well ive noticed on the Tube it has a Thomson sticker, with a load of numbers on,

Does this mean i would need a service menu code for a Thomson TV? Also is there a Pot on the main board anywhere that would adjust the Vertical screen size of the TV?

Cant you get a qualified engineer to look at it.Sometimes you can do more harm than good.

No, The TV manufactured by another company for Toshiba uses a Thomson crt.

No...it's all done by software.
If the symptoms are excessive height you may have a fault.
Any other symptoms?

Theres no fault with the TV, i shall be using it to go into my Arcade Cabinet that im building. The TV shall be connected to my PC via a home made scart cable. The problem im having is when used with the PC, there is a slight overscan, and just wanted to adjust the picture hight, to sort out the overscan

Well sent toshiba a email asking them if they would tell me the service code, and they replied saying that they could not tell me over a email or phone call, and i would have to have an service guy come out to input the code! Yeah like im going to pay a call out charge just for some guy to come and input a code for 5 seconds. So there is defently a code for this model then, i dont know why they just couldnt of told me the code in the email?

They wont tell you because you are to be qualified before you attempt to make adjustments.It could be a fault and if you start messing with adjustments then take it to a QUALIFIED ENGINEER he has to sort out your mess first.I have had it too many times but the problem being they dont even bother to tell me that they have been tampering which makes my job harder.
I went to college for 5 years to learn this stuff.......So you are paying for his expertise not to mess things up

Well seeings as i shall only be changing one value on the service menu, i dont think i shall be messing anything up, as i have done this a few times before, and i know not to mess around with anything else as it shall end in tears

I've got a Tosh 32" which had/has geometry issues. The engineer did as described but it took many attempts before it went into service mode. Maybe it's worth trying over again in case it's designed to not work every time, just to put unqualified people off?
The engineer did show me how to change settings though, but he did show me some which must not be altered.

So he pressed mute on the controller then released, then pressed and held while press the menu button the TV?

He seemed to keep pressing both randomly, and most of the time it went to the normal user menu screen. Then it did eventually go to the engineer's menu, which is just a small box in the top left corner with the TV picture showing through. I used R1 Terminator 2 with the THX test patterns on it. It showed the failings of CRT TV, and he did improve geometry, but it is still not perfect. I'll probably have to go plasma/LCD for perfect geometry.

I also have the Toshiba 28N03B connected to Pace Sky+ via RGB scart, but the picture looks very grainy and washed out. What are the ideal settings for brightness and contrast? I've got brightness set to 50 and contrast to 80.

Thanx in advance

It’s down to personal taste. I prefer s-video on mine as the rgb on my set is a touch pale (not grainy though). Also you can increase/decrease the the colour with s-video.

For rgb, try lowering the brightness to between 40-45 or which ever suits your eyes.

It shouldn't look "grainy"...are you sure you are watching it via AV scart?

sajan · 05-06-2006, 7:21 AM

Thanx for your suggestions guys. I've got my Sky+ connected to AV1 on the Tosh via a IXOS XHV601 RGB scart lead and it's definitely RGB because I can clearly see the difference in picture quality when I switch between PAL & RGB in the Sky+ picture settings. Turning down the brightness from 50 makes the picture too dark. I might try connecting Sky+ using s-video to see if that improves the picture.
