Check SMPS voltages. Check optical coupler. Check SMPS components. It is difficult unless you follow a circuit diagram.

Sometimes replacing opto isolator may solve!

Caution : Do not switch on T V without opto coupler. ( if you remove for checking ) replace with new one as it is difficult check with service test meter.

Pool heater wont start but when i turn off the pump and start back again the pool heater comes on for 2 seconds and shuts off AGAIN


Heater must have water before it will fire up. There is a delay relay that may be dozing off. Not a bad thing but should be chk'd by a pool sevice.

Could be bad batteries. I suggest rechargable batteries since Samsung usually drains batteries really fast.
