HT-Z410 ~ 2 years old "chk fan" message 2 min after startup; then shuts down. Home repair? How to find new fan?

More that likely the fan is going out. Check the fan exhaust to see how much air it is moving if any. A laptop cooling pad will probably help out and possible prolong failure. If its under a year old, the maufacturer may fix it for you. You'll just have to contact HP and see if they will, or if they can get you a new fan to replace yourself if they wont do it for you.

It means the fan(s) aren't doing their job. Clean out the dust bunnies and see if that helps.

The processor sense problem on your fan then shuts down the unit to avoid further damage to your output IC from overheating..
It can be DIY by cleaning the fan,sometimes it is full of dust thats why its stuck or might be faulty already. If the fan is defective then replaced it with a new one.

After that if the symptom is still there then you might have a problem on the board.
This is quite technical and need to send to repair shop.

Good luck.

Pls rate my help.

I've advice you to check your exhaust fan if working properly.
The processor shuts down the unit because it sense that you have a problem on the fan.
This is happen to avoid further damaged to your output I.C. which is quite expensive.
If the fan is not working then try to clean it, sometimes it is full of dust that caused to stop from functioning. If you confirmed that the fan is already defective then replaced it with a new one.
After replacing and the symptom is still there then I've advice you to look for a qualified technician because there might be sometime wrong on the board (faulty parts).

Got that exact same problem and do not know what to do. Help !!

Did u ever find a solution? The room I use the home theater in gets quite hot. I use an air conditioner but I think prolonged use in the heat has ruined the fan(s). The speakers will power up, and sound can be heard but after a minute or two the CHK FAN will come across the display, and ultimately, shut the system off. Is this what happens to you? T?hanks for any and all responses!,

it means the home theater is over heating and the unit will shut down to prevent any damage. This can happen if the unit is stacked along with other electronic devices or the unit is in an enclosed area that prevents the unit from cooling properly. To decrease the chance of overheating, relocate your home theater to a more open area.

If the home theater display reads PROTECTION every time you turn it on, no matter where or how the unit is placed, it needs service. To set up service call Samsung Customer Care at 1-800-SAMSUNG (1-800-726-7864). Have your model number and serial number on hand to set up service.

protection error message means that your unit's fan is not working

it is a feature to keep your unit from overheating

check if there is anything blocking the fan of your unit from rotating

if problem still persist replace the fan

The fan is going bad and if you have replaced it try to open the case and remove the cover over all the capaciters and what not and replace that fan in the back then cut a hole in the top of the metal case directly about the cap's that warm up and install a aditional fan to act as a chimney a little noisy but i did this and the player had been runing in aux and radio mode for a few days stright now no problems at all it's alot of work and skill but for 2 5-15 dolar fans sure beats the 160 for repair or buying a new recever! make sure u turn on the recever for 10 min if the fan is not turning by then its still not good

Looks like it is to do with the rear wireless speaker. Now, my problem is over. Its gone. I first turned the reciever on and then turned on the rear speaker wirel less on. No rear chk in problem now. Hope this helps. R.
