Re: Vizio VO42L FHDTV10A No Power
1) Why? You are doing a great job. 
2) BTW, now you understand why we always INSIST on good quality pictures of the OP's board and not some stock photo or reusing other people's photos. Without the OP's board photos, you would have never spotted all those burned out components.
3) I would also check BD1, the bridge rectifier, for shorts. Number the pins 1, 2, 3, and 4. Measure the resistance between pins 1-2, 1-3, 1-4, 2-3, 2-4, and 3-4. Any reading under 30 ohms suggests a short and must be desoldered and retested out of circuit.
4) I would also suggest recapping this entire power board. Since you got this TV for free, recapping the entire power board will probably be less than $15 USD. Poor quality caps will allow too much ripple into the components.
What are the original cap brand and series?
