Hi all, newbie here and as you will quickly gather not very clued up. Please help me with this problem. Just bought a new Sharp LCD (15SH1E ) and am pairing it with a new Pioneer DVR 420H. Problem is this. The dvd has a built in tuner which I have set up and all existing channels transferred to the dvd player no problem.A good quality scart connects AV1 to TV scart.All goes swimmingly until I swtch off dvd then picture breaks up as if antenna has poor connection.Sharp manual not very helpful. (1 )Straight forward antenna connection to tv =brilliant picture (2)Antenna into dvd + Antenna from dvd to tv with dvd switched on =brilliant picture (3) Switch off dvd= lousy picture I hope there is a simple answer.
