The issue I have with my tv is similar to the other power down issues. I press the on button and you can hear the relay turn on, tv charges up but no picture and then you can here the relay turn off. The reason the tv is doing this is because it was disrupted by a lightening strike outside the house. I placed the tv into diagnostic mode and it spit out the 2-4 code. I checked the 9 fuses on the two boards and they all passed a continuity test. I then started to check the 3 boards for any visible failure and I think I found the cause! A failure of the PNP 12v switch labeled Q9A20. Here are two pics. Your technical guidance would be appreciated. do you think I can just soilder this again or should the component be replaced? I looked and found radio shack sells a similar component but i am not sure if it is the same. Thank you for your time.
