Strange colour problem , Ferguson FL15DX5 LCD tv
ProDave:
Thanks for that. I had kind of figured that out but not the exact button sequence.
Now in service mode.
When in Dtv mode, it brings up settings for "YCbCr" so I presume that's how the DTV decoder is connected.
There are settings for R Gain, G Gain, B Gain, R Bias, G Bias and B Bias.
I can get pretty close to a normal picture by cranking up G bias (all bias settings are at zero initially) to something much much higher, and tweaking G gain.
So there might be hope for this set yet.
It still seems to me though, I'm patching up a problem rather than fixing it.
Next problem. How do I get a DTV test card or colour bars? I certainly don't have a DTV pattern generator.
I'll try the same with an RGB scart input where I can more easilly get a test card to play with. When I get more time that is.

You can display the test card on any reasonably new Freeview receiver
using the following steps. Note that some older set top boxes do not
fully conform with the specifications and may be unable to access this
service.
1. Tune to the BBCi channel (currently ch. 105)
2. When the BBCi background appears, press Yellow (within 30 secs)
3. Tune away to a different channel
4. Tune back to the BBCi channel (currently ch. 105)
5. When the BBCi background appears, press Green (within 30 secs)
The word 'Secret' will appear in the top right hand corner
6. Wait until the status page appears
7. Enter 3, 3, 5, 8, 2, Red, Green, Yellow, Blue
(note "33582" spells out the word "DELTA" on a mobile phone keypad)
8. Wait approximately 30 seconds
Test card will appear

ProDave:
Thanks that works. But..
Press Red, Green and Yellow ONLY. Pressing blue brings up a page of "credits" about the designers that you can't then remove.
Anyway, I've now given up on this tv for a number of reasons.
Firstly, while I can vastly improve the picture problems on freeview, I can't get it correct.
Secondly, I have determined this is a really c**p tv, even when working. The freeview tuner keeps dropping channel 5 from it's channel list unless you rescan mux 2, then it comes back but only for a while.
Thirdly, on freeview, the lip sync is abysmal, and the picture shows far too much noticable compression artifacts, something you shouldn't see on such a small screen.
So I'll be selling this one again, and to be fair to buyers it will be described as faulty

Hi,
I've just read this topic-> this is common problem in this TV. In this TV white balance settings for DTV are not the same as analog inputs, you can set it in service mode (all settings are in EEPROM). Do you have EEPROM/FLASH Programmer?
