Thank you for using just answer i ll be happy to assist you today,first off can i ahve the model # XXXXX the tv set,also do you have a power surge protector between the tv set and the wall outlet,moreover what have you tried if anything to correct the problem thank you.
Ok zobie the 6 blink SOS is possibly a defective board. It's referred to as the SC board Energy recovery trouble mode SOS signal.-Start by removing the SC2 and SC20 connectors from the SC board and power up the TV (unplug the television when disconnecting). If the TV powers on and stays on, replace the SC board.-If not, reconnect SC2 and SC20, then disconnect CN P12 from the P board and SS11, SS34 and SS23 (this may be SS33 in the 50 inch model - it is the sustain data connector) from the SS board. Put the jumper from SS34 between pins 8 and 10 of P12 and power up again (unit won't go into standby w/o this jumpter). If it stays on, replace the SS board.-If not, reconnect CN P12, SS11, SS34, and SS23 (or SS33). Remove the A board block assembly to gain access to the D and C boards. Ground the base of Q302 on the D board and power on. If the power stays on, reseat the ribbon between the C boards and the D and C boards.-If not, check w/ a voltemeter is the P board outputs 15 volts at pin 7 of P7 and Vsus of pin 1 at P2 before the TV shuts down. If not, replace the P board. If so, replace the D board.On the links below you should be able to aquire the service manual for your tv set,this is very important to have since it will help you locate the circuits,hope this helps.
