Hi Gang Samsung Plasma S42SD-YDO1 shuts down. It makes some noise before its shuts down. Like shorted component. Customer compains that tv was shutting down and sometimes coming on and work then shuts down again. I took the back off. Unplugged the all the bords from them main power supply board. And turned on the problem still there. Looks like the power supply board is the problem area.I look for any shorted component on the board but so far no luck. I have no service manual and also no tips for this set. I am hoping that some of you worked on the similar model and have service manual or any tips for it. Thanks in Advance. email to: alltv@xxxxxxxxxxxxx ************************************** All TV Appliance Service * Ken Dinckan * * 2747-B Roosevelt Street * Carlsbad CA, 92008 * (760) 434-1131 * *********************************** ----------------------------------------------------------------------------- This Email List is accessible to the general public through search engines.
