Question about Samsung HCM4215W 42" Rear Projection Television
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.
