LG L226WTQ-BF goes black after 15-20 seconds

My LG monitor turns on fine but goes black after 15-20 seconds.

I purchased the capacitor repair kit on this site. I installed the following capacitors.
1000uf 16v
1000uf 16v
1000uf 25v
680uf 25v
680uf 25v

Just after replacing the capacitors the monitor seemed to stay on for about a minute the first time I turned it on. Then it went black again and after powering off and back on will stay on for 15-20 seconds each time before going black.

Are there other capacitors I need to replace that would cause this problem? I saw on another post there are a couple other small capacitors that could be replaced, though they don't visually look bad. Would they cause this issue? I think they are 1uf 50v and 47uf 50v

Anyone have a suggestion on this issue?
