Rt2250 rt2500 speaker static noise hum buzz until fully warmed up

I was given this unit used and have had it for about three years. It has had this problem and seems like it has gotten worse as time goes on. When I turn on the system, it has no regular sound, just buzzing out of the speakers. If I turn it up more, the buzzing gets louder. I can see a green light is on inside the unit towards the back. When the unit warms up fully (about 20-25 minutes) then the music starts to come in choppy until it finally is fully warmed up and it works well. When it starts coming in the light flashes, and then when it is working fully, the light is off. It does not matter

I had the same problem humming when first turned on, replaced the 6800uf capacitors works fine now, sound better than its has for a few years.
It sounds like a capacitor in the power supply is just about to die. With the power disconnected have a look at the large tin can looking gizmos near the power transformer. There could be a couple of them. Leave the unit switched off for a while before going near them they could still pack a splat. Replace them with the same value and make sure they're connected the right way and it should solve your problem. Whilst in there have a good look for any other smaller capacitors which look as if they're getting rounded at the top. Replace them too. Either that or dig deep and buy a new one.
