Question about Samsung HCM4215W 42" Rear Projection Television

1 Answer

TV Turns Off Automatically While Watching

The TV turns off randomly (at various time intervals, sometimes minutes, sometimes hours). After I push the "power on" button like 6-7 times the TV will come back on, but then shut off again shortly there after. I've also recently noticed that right before the TV turns off, it starts this hissing noise and sometimes the screen will pulsate and flash before turning off. Any ideas/suggestions/possible solutions???

Stop trying to turn on the set. You are causing more damage. The hissing sound you are hearing is either a High Voltage Transformer on the SMPS (Switched Mode Power Supply) indicating a short somewhere in the set or some capicitors that have shorted out. Also there can be a CRT that is leaking cooling fluid onto the Main bd or the Power/Deflection bd or both bds. Have a trained Samsung tech troubleshoot the set.

I have the same issue on my Vizio M470NV. I called Vizio and they told me it is a self diagnostic test that is shutting down the TV automatically to protect it. They said they are working on fixing the issue with a firmware update that will be pushed out automatically if you are connected to the internet. No ETA given on when that would happen. I called them on the 3/14/11 and my TV is still shutting down randomly.

Hello, my Marantz BP8002 keeps shutting down intermitantly with different type disks. Does not matter if it's Blu-ray, DVD, or DVD-R. It will sometimes play for 2 minutes and shut down completely....


If it shuts off at different time intervals, there might be a loose connection that needs to be solder. Ask for a repairman to check it.

LG TV Turns itself off


Sounds like it could be a poor connection in the power plug or a ' dry joint ' on the power board, if it's the latter, it will respond to light thumping at the side of the tv. If that's the case it needs resoldering by a technician..
good luck !
