Set will not power up. Has 162V on primary of switching transformer. Nothing on secondary. No shorts evident in secondary. Need Schematic.

Thank you all.

change out the buffer q 507 i belive and the zenor d 507 and the opto look for puffed caps in the deflection board , what happens is the buffer leaks and sends the b + up to 200 plus, on a 127 line caops don;t like that.

Unfortunately can not locate Q507 or D507.

Thanks.

Sorry about that in this model it is ic1702 q 1705 and d1703

Hi David! Thanks a lot. Your information is very helpful. Can you provide part numbers for IC1705, Q1705 and D1703? Thanks.
