Brendan, do you mind taking pictures of both sides of the power board?

I have modified the power board to use a meanwell, works fine on my other Dragon

Ok, according to the service information, this is what you could try: C. Faulty Colour 1. Adjust RV1 (and RV2 if fitted). 2. Alter value of C7. 3. To obtain full green screen or to cure 'rainbow effect', fit a 2-22 pf capacitor trimmer instead of C7. 4. If colour fault on 22" or 27" SONY sets, then...

Will check, thanks

At work at the moment will do when I get home

Hi,

This is the board

Hi All,

I am trying to repair a Dragon 32 everything works fine but its in black and white. I have tried changing the pots but still the same, I have also resocketed and changed the LM1889 but no difference. Any ideas were to go from here would be appreciated.
