| Sears 509-14370 TV, chassisA67, made by JVC, the board is labeled CKF0822-DU3-1. TV turns on when first plugged in for a couple of seconds then shuts off afterward, only a slight relay click. Repaired bad solder & replaced defective parts D541=RGP10J (shorted) & R341=1.8 ohm,2w (open) located at the T522=FSM-27A001=flyback then IC421=LA7832 exploded. I checked most components around IC421 but no luck. |

| Answering my own question, I replaced C424=100 uf,35v along with C425=470 uf,35v C427=2200 uf,35v and IC421=LA7832 again now the TV runs great. |
