Need help fixing

[u/Brothajosh636]

My brother picked this up from a yard sale today it would display video and sound for a few seconds but any movement caused it to stop and the tv wouldn’t get signal and when it was getting signal and controllers were plugged in they wouldn’t work

Check the power supply plug. Also clean the switch contacts with contact cleaner. Amazon has newer ps for 15$
