Probably a 'cold or detatched' solder joint on a component on that perticular circuit board you are 'wedging' with a plastic rod.

check the solder around the area of the vertical IC. solder is either cracked or else cold. Cold solder appears as dull. Resolder anything that isnt shiny.

if the power button is blicking red then most likely ur lamp needs to be replaced. they dont come cheap but its an easy fix ...try ebay for the part ...and make sure u get the correct seze and watt for that specific tv ....on a side note...if u replace the bulb yourself....wear latex gloves and DO NOT touch the bulb. the oils on your skin will magnify the light and can cause that bulb to explode or pop and then u will be right back at squareone
