I am attempting to repair a power supply for an LCD display. It failed to power on and there were 6 bulging caps that I feel confident are the problem.
4 of the 6 were in a row close together. I removed them all, without realizing that they were different values. Now I am not sure which values go into which place on the PCB. 2 were 470 uf / 25v and 2 were 1000 uf/ 10v. They all four appear identical, other than the markings.
I am trying to figure out my best plan. I cant find any info online about this particular PCB (TDK- model XAD819AR). I have no problem with experimenting with different combinations, but I dont know enough about how they work to know what to avoid. I understand I should never subsitute a lower voltage cap for a higher voltage one, but that the reverse is not true. How about the uf rating though? Could I safely install 1000uf 25 V caps in all four slots without (likely) destroying something else? Would the higher uf rating cause other problems either immediately or later on?
Is there another approach someone could suggest?
Thank you for any guidance.
