I have a problem - Last September I had my DSP (large Amp) & radio (small silver box) unit revamped which when refitted allowed the Radio, Satnav, TV, speakers all to work great. Last week my display went off whilst the radio was still working. Couple of days later my speakers went off and I lost my Satnav plus my display went from an orange back ground to blue, my computer display section is showing as is my radio section section. I removed the large Amp to find that one of my pins on the large plug has nearly rotter thro but dont know if that is the reason for the display change - all help welcomed, many thanks.
