Hi,
Thank you for answering.Short after i wrote D3 and D4 and D11 began to give a greenblue light and the part on which is the number 220 began to get so hot that its isolation lacqer began to stink breathtaking but in spite of this the screen was showing :Black Widow ready.
Because i thought that the two diodes and the coil are not working any more i ordered a new board and am now waiting for its arrival.
