Hi, the DMR E85H and some other similar age Panny's have a problem with the power supply board cause by a failing 5 pin integrated circuit which stands proud of the board like a transistor. This means the machine never powers up properly and goes into a 'self check' loop. The fix is below and a competent electronics repairer should charge around £30 to fix if you source the component which costs around £5 -£10.
