    Default Dreambox DM500s Low audio problem

    Hello everyone,

    I have two units which are from different manufacture's and there both have a low audio output problem via RCA and SCART outputs.
    Can someone point me to which cap's or components might be causing the issue.
    I have tried multiple Gemini images and PLi but no difference and I do have a working unit which has a normal volume level, so it isn’t my TV.

    I bought both units from overseas via eBay so I don't have warranty.

    Here ya go.

    have a play with R121,122,123 and R124,125,126

    You may need to cut pins 6,7 and 1,2 of U11 and wack in a couple of resistors to give it gain as it seems to be in unity gain mode.

    R110 and R111 are worth toying with as well (near output jacks)

    I'm surprised Avtech hasn't got on to this.
