Reset for Samsung ML-1660 ' FixYourOwnPrinter

The set has a power supply circuit board INSIDE that needs to be looked at (not the power cord itself) and if bad replaced.

Same issue with - Panasonic TH-50PX70A , power UP with red standby, then power ON by remote - only Gives GREEN led blinking 35-40 times, followed by solid green led with no no picture no sound.
>> Solution; unplug Plasma from AC 10-15min, then plug in & power on to Red standby led,, At this point - Power ON tv while holding down both -Volume Down and F (function Select) buttons (front panel door) at the same time turns picture ON,all ok.
