I recently purchased a samsung split a/c as24eta series. whenever the compressor cycles on, it starts making sort of rattling and humming noise and automatically switches off on its own. can you please help?

indicates dirty evaporator fins that are icing up
that will overload the compressor and trip it
the ni oise you hear is the ice breaking up and the splashing is excessive water in the blocked drain that cannot run outside
get in a technician to clean and service the ac
This could be caused by an installation problem. The system could be severly overcharged, causing the compressor to load up and can cause a failure. i would start there. Is your intaller qualified to install these systems? (does he know what he is doing?)
I recommend, checking the refrigerant pressures first. You can also check the Polarity of the high voltage in to the outdoor unit. If the compressor is an Inverter Drive compressor, and the polarity is reversed, the compressor can run backwards causing the noise and eventual failure. To correct a polarity problem, simply remove the 2 high voltage wires that feed power to the outdoor unit from the board or contactor. Then reconnect those 2 wires, in the opposite position. (say you take loose from the unit and the Black wire is on the right side, and the white wire is on the left side. Simply swap sides, reconnect the Black wire on the left side, and the White wire on the right side.
If your fan motor is slowing or stopping mid cycle it will cause the compressor to over pressurize. Many compressors have aan internal mechanism that will kick in with a loud whooshing noise, then the Thermal protector shuts the compressor off, cools then restarts. If this sounds familiar, you will need to replace your fan motor before you burn up your compressor...which to be honest may already be irreparbly damaged(sorry). Hoping 4 the best.
if it’s a banging sound--- I know one of the noises the system 2000 will make is a bang or rattle at the end of the run cycle, which we call "shudder stop". If this is your noise then I have to give you some bad news here. Sorry.......
The only way of repairing this is by having your compressor replaced as it has to do with an internal problem in the compressor itself. There may be a silver lining, though, if you are the original purchaser and you have the receipt. Some of these systems came with a 10 year warranty on the compressor, so you might want to check this out.good luck
If the noise from the compressor sounds like a humming followed by a click, the compressor is "short cycling". Could be either the compressor relay or the compressor itself is bad. Not sure on the hissing noise. Could be just a loose panel that needs to be tightened or adjusted.
Your TV may something arcing inside of it. Maybe a loose connection. Since it is probably under warranty you should get in touch with the dealer where you purchased it. Perhaps you can get the whole TV replaced.
