Narrative:
After departure; 15 minutes into flight; we leveled off at 6;000 ft; entered IMC conditions and light to moderate rain. First officer's electronic attitude direction indicator (eadi) and electronic horizontal situation indicator (ehsi) screens went black. Captain's screens also flickered on/off at the same time. The first officer's screens did not come back on right away. Minutes later first officer HSI screen did come back on but ADI did not. Controls were handed over to me immediately and we requested a return back to [departure airport] and out of IMC conditions. Landed with no incident.
