I’m assuming you meant the internal capacitors have been replaced? If so are they of the same capacitance? A higher operating voltage is fine along with lower ESR, high temperature rating.
If they are not the same capacitance then start there. If the capacitors were replaced due to a fault what was it? If the capacitors are the correct value / voltage rating there’s an obvious component fault still present such as a power transistor.
Please indicate the model, serial number of the unit in question with a photo. It should show the entire mother board, front and back of the units housing.
Brain Dead: This procedure will attempt to reset and clear any possible errors in the units processor. Disconnect AC Mains, disconnect the batteries, press and hold the power button.
You may hear a click & beep confirming the process is complete. You may not hear anything so be aware.
Report back if the fault is gone . . .
NOTE: Before attempting the brain dead procedure gather any logs, error codes, and past faults and relay the same here.
