I mean that your unit is need of resolder or reheating of the solder joint of the parts.Supply section,horizontal section,vertical section and microprocessor IC.Improper distribution of current flow ,due to a loose contact or crack solder, that's your tv automatically signalling by flashing,that is the main cause of flashing . Find a tv technician to do works for you,,in order to avoid high voltage shock....

    cold solder issues - each component is soldered into small holes on
    the printed circuit board which in turn connects said component to the
    other components. Due to time, heat, use, some solder joints would be
    cracked or loose. It is possible that the cold solder is still
    minimally connected (hanging by a thread). When the TV turns on heat
    would be generated which would be sufficient to further loosen up the
    solder joint to the point it no longer provides electrical contact.
    Jarring the unit creates movement inside enough to re establish the
    contact, sometime good enough sometimes not enough.

    Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection,
    solder joints are "connections" except that molten soldering lead is
    used to attach/connect the component to the board, "loose connection"
    in this sense is equal to "cold solder".

    Again on the assumption
    of no defective parts, then seeking a more experienced buddy for the
    soldering might be to your advantage. This is of course in addition to
    the possible electrical hazards when repairing the inside of a TV unit
    for any lay/unexperienced repair person.
