Albert, both failed capacitors were in the power supply. The ez27 has now been operating well for several days. When I started the repair, I ordered replacements for every aluminum electrolytic capacitor. I only replaced the two that showed visible damage, and then I tested. The desoldering is not easy, as lead-free solder is used. Its higher melting temperature makes it somewhat challenging to rework. I felt that it would risking damage to the circuit board to replace all of the capacitors.
