A lamp that is near failing can still look OK, the higher current draw will shut down the set. The ballast could have a component or components that are breaking down under load. One of the many PC boards, wiring, sensors, or color wheel could have a problem. An experienced servicer could save you time, money, and aggravation.

Picture on my rear projection samsung tv is good but a buzzing sound starts and when you shut it down it slowly stops like a fan or motor

Only seen 2 bad fans on these. Most likely the color wheel (bearings going out). It will get worse to the point the set will no longer turn on. You could replace it yourself but you couldn't align it. Best to call a local shop that you can trust and have them do it. Make sure they're an authorized Samsung repair shop because they'll get better price on the part.

I have just inherited a samsung HLP4663W, It had a color wheel that was making noise. I have replaced the color wheel. Now I am getting a fan speed warning. it will come on but shut off after approximatley...

You have 4 different fans inside of your TV. The biggest challenge - to pinpoint which one is bad. I would recommend just to get 'em all and replace 'em all. They will start fail one after another anyway.

I have fan#1 and Fan#2 message on screen.It won't allow me to get on to service mode.Both fans are working, replaced actuator board, nothing. I noticed power board is sending 205V DC, and actuator board...

Check to make sure that both fans stay turning.If one stops prematurely, replace the one that stops. If they do turn until shutdown then try jumping the Temperature Sensor on the Lamp Housing. If that stops it from shutting down, replace the Sensor. If not , there is a chance you have a Actuator Board or a Digital Board causing the problem.
Hope this helps,

TV on/off

How long is your TV on before it turns off? Check the fans and make sure they are all working. The TV may be shutting off due to overheating if a fan quit working.

If you think the lamp is still good maybe try replacing the lamp ballast.

Sporadic Hum on HLP4663W

I would guess that its the fan for the lamp, as the color wheel will power down as soon as the power is cut. the cooling fans will continue to run
