The problem with your set is 4 capacitors are bad on the "DM: board in the unit. These capacitors are 1000 microfarad at 16 volts. Unless you are experienced, this repair should be done by a qualified tech due to the complexity of getting to the capacitors

There are four (4) caps on the 'DM' board that need to replaced. Parts: 680ufd 16 volts, orig are rated at 1,000 ufd.

bad capacitors 1000uf on the PWB, FMT and DM boards will cause those symptoms. All capacitors 9 in all need to be replaced

replace C81A2 C81A3 C81B2 C81B3 on the dm module and C8F19 C8F21 C8F22 C8F27 on the fmt pcb all new caps should be 680uf at 16v instead of 1000uf at 16v

There are (4) 1000uf @35V capacitors all together on the DM board that need to be replaced some models have 1000uf @ 16V but they are all right beside each other and all rated at 1000ufs the voltages will be stamped on the capacitor along with the uf ratings.
