Problem with samsung UN55C6500 TV inadvertanly power problem TV unexpectantly changes modes and will power off. the on/off red tv lights is flashing when trying to power back on.

SOURCE: tv won't turn on

Your problem could be the Convergence board is loading down the power supplies and will not let the TV set come on, or the power/deflection board, part number AA94-08574A, or the STR type regulator IC, part number AA13-00105A. If you locate the convergence board, unplug the connectors, and see if the set will come on. if the set does come on, replace both of the STK convergence IC's at once. The part numbers for those IC's are STK392-40. You can get the original replacement IC's from MCM electronics for about 15 to 16 bucks a piece. Do not use the less expensive STK IC's as they are not the same. the replacement IC's should have the name of SANYO printed right on the face of the IC's. Good Luck

If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at www.tvrepairworld.com just leave them a email they respond quickly.

Most likely the set has lost vertical sweep or the feedback from that circuit. This will shut the set down to prevent a horizontal line from burning the face of the CRT. This will have to be looked at by a technician.
