Narrative:
Earlier that morning we operated aircraft X from ZZZ1-ZZZ. On the landing rollout we had an electrical anomaly that caused several of the primary displays to go blank. Upper EICAS; ca (captain) pfd; mfd; FMS; and first officer (first officer) pfd. This was subsequently followed by a strong electrical burning smell. This was entered into the logbook with a few other discrepancies. We reported later that afternoon to operate aircraft X as different flight number from ZZZ-ZZZ2. Local maintenance said they have been troubleshooting this issue all day and believed it to be a screen overheat caused by a faulty pack valve. The logbook was signed off and we blocked out to taxi for takeoff of runway xx. On takeoff around 400 feet the screens again went blank. We continued flying using the standby instruments. We indicated to tower we needed to return and she handed us off to departure to be vectored for an approach; the weather was OVC008. We notified ATC with departure and was vectored back around for the ILS xy. After landing the fire marshal entered the cockpit and indicated he smelled an electrical burning smell. This was once again entered into the logbook as a repeat item.
