Jeddy,

Based on your feedback it seems that the BeoVision IS receiving RGB from your STB, the picture will not be viewable because of the lack of sync pulses as others have pointed out, but in your answer you do state that you DO get a picture, albeit rolling etc, so cutting pin 19 & 20 has proved that.

So, we can now be sure that the STB is sending RGB and the BeoVision 3 is processing it and can display it.

However, when CVBS is present it appears to default to that rather than RGB regardless of settings.

So, my conclusion based on the information you have provided to date is that your cabling (subject to you re-soldering pins 19 & 20) and your STB's are fine and the problem relates to the Beovision itself its software or setup.

So, the following questions come to mind:-

1. How old is your BeoVision 3-32 ?
2. What is the software version of your TV, You can either look for a small label on the back of the TV or go into the service menu under "Monitor" ?
3. Has your BeoVision 3 ever worked in RGB mode ?

What are you looking for in the picture to se if it’s RGB or CVBS that’s on ?

If you go  into the service menu, Monitor, Picture adjustment, Colour adjust, it (presumably) tells you what it is using (CVBS 043), I can also flip to the other setting RGB 064 which does change the picture.If you go into e.g. the program guide on the STB (loads of text - thanks for that tip) and look closely, under CVBS all the text looks like it has ghosting - if you flip to RGB this goes away.

This is where it gets slightly embarassing 😳 I had assumed that since every time I went into this option it showed CVBS that is what the picture I was normally getting was. However while writing this and looking closely at the set what seems to happen is that when you go into this option the picture is indeed CVBS, however when I come back out if resorts to RGB so I may be getting RGB all the time.

However all is not well so please bear with me. The reason I ended up here is because I all to often find the picture unwatchable so I ended up trying to change service menu settings (yes, I know the risks and have tried to minimise this by making a note of the original settings, which is fine so long as I can see a picture to restore them to those values) and RGB was one I was hoping would fix my problem.

The problem I'm trying to fix is again particularly noticable with text, but also other things (most noticibly with sharp edges) but only on some programs. Those of you in the UK will no doubt have seen the new weather that one of the channels is doing where they fly over a map of the country which has place names on it - depending on how fast they move you sometimes can barely read the place names because they are so jumpy, and yet when the slow down slightly it is really clear and smooth.I have tried the Movie mode, however this has as many problems as it tries to fix in my mind and I'm sure that without this the text etc. shouldn't be as jumpy as it is. The problem is only ever with things moving left - right or right to left - up and down is fine (you can see this from credits at the end of programs, those going right to left jump between being legible and not - while those going bottom to top are always fine. Sometimes the right to left credits are unreadable and after 5 seconds suddenly become smooth and then go back to jumpy again. If it was just credits I could live with it, but in some programs it is very noticable (e.g. The Apprentice) - it is almost like 10fps instead of 25fps when stuff is moving fast across the screen. Could this be the problem, the set can't cope with so much motion??! Surely not.

 I normally only watch through the STB / Tivo, but it appears that the problem exists on TV from the inbuilt tuner (ok, it appears RGB was a red herring, I wish this had occurred to me before). It is also harder to work out what is going on from here as it's obviously only live so you have to wait for a particular program to have the problem.

Maybe this has been fixed in a later s/w version? Mine has EEPROM ver 043

I do hope someone can shed some light on this problem otherwise this set has been a very expensive mistake which has to go...

Many apologies for the RGB confusion and thanks so far...

Well Jeddy, I am pleased you cleared up the situation with RGB, some of us were pulling our hair out trying to understand the problem.

Your EEPROM 043 is not the software version, but the new issue you have raised could be a software issue.

Perhaps you could answer the following questions to allow us to determine the situation

1. How old is your is your BeoVision 3-32 ?
2. Is it a Mark I (Type 880X) or a Mark II (Type 881X) you can find the type number on the back of the set ?
3. Also on the back of the set should be a very small stick-on label with the software version # on it.

If that fails you can go into the service menu and look under "Monitor" and you will see something like the following except the picture is of a Mark II AVANT. Notice here the system software version is 8.5

thanks guys,

To answer the questions

I'm not sure how old the set is tbh - it's 'pre-owned'.

Its a type 8813

s/w version 13 according to the sticker on the back and the monitor information on the menu.

I take the point about 100Hz, however don't think this should explain the problem - my previous set (a Loewe Acconda until the tube went bang after only 5 yrs) was also 100Hz and much better in this respect. I also don't think it explains why some programs are bad and others fine with similar material. Going back to 50Hz also isn't an option, I'm one of those who find the flickering too bad on those sets. If the problem is the videoprocessor is it just that the one in the Bv3 is poor compared to other makes (I'd hope not, the set may be 'pre-owned' but it still cost a lot more than a new one from a mainstream manufacturer would have cost.

I think I know what you mean by a live teletext picture, but haven't seen this that I can recall on this set. 

I'll see if I can get a picture of how bad it looks, sometimes it really does look like two superimposed pictures on parts of the screen where the movement is.

Jeddy,

Lets start with the age of your BeoVision 3-32 it is actually a Mark III which was introduced in July 2003 and last sold in 2006, so a fairly new TV and your software is quite up to date as well. The latest version is 15.3

You talk about two superimposed pictures on parts of the screen where there is movement and whilst I understand Beobuddy's comments about 100Hz, what you are describing seems something different. I think you are correct we need a picture.
