2L25 Bay 1 and bay 4 not going to HV. Found two damaged (burned) din 120 VAC distribution blocks and no 120VAC powering Bay 4. Repair when we locate new blocks. Bay 1 has a DSP low battery fault on the battery backed RAM and lost all loaded values. Spare Display control board to go into bay 1 tomorrow after 120VAC repaired. The loss of 120 in bay 1 may also affect the memory loss in bay 1. Techs: Chris, Sam, Xavier,Gunner,Trey, Alex.
