Sounds like main module failure. We stock it at ÂŁ39.90+vat plus postage of ÂŁ5+vat. Go to our site at www.emwelec.co.uk and put A1635 in the search box or call us on 0115 9652118. If a module does not sort the problem out, you can return it within 14 days for a refund, less our handling charge of ÂŁ9+vat. Tony EMW Electronics
