Title: HELP! Samsung LN40c550J1FZXA On/Off Issue After Changed capacitors
Post by: zebra100 on July 19, 2012,00:48:40
This set started turned on/off several months ago.  Called Samsung, they said this model is out of the range of those sets.  I cahnged all the capacitors (they didn't look bad), still on and off, updated the firmware via USb, still same.  Found a friend have same set, swith the power board just to test, still same on/off, seemed not a capacitor/borad problem (though his board seemed a little diifferent).  Then just let it switch on and off ( it wil styed on 2-5 seconds then off, then flash red dot and 2-5 second switch on again and repeat this process about half hour then it will turn on permanantly, even you can switch it off then on it will be normal .but if turn off half to hours, it will on off again.

I read Samsung LE model has a eprom corruption problem, is this model also has it after cahnging the capacitors? :03:

This model doesn't even have a power button.  It can only power up/controlled through remote.
