Tds refund enquiry

can anybody tell me, a return was filed in physical form for AY 2014-15 and had a refund of tax but no tax refund is received so far. Can a revised return u/s 139(5) against the physical return be filed electronically in the AY 2015-16 and tds refund be claimed? If not, then what is supposed to be done to claim previous tds refund in the AY 2015-16?
