Question about Televison & Video
This symptom indicated of drop/missing of output voltages in the power supply section. You must check each output voltages in that section feeding the main board and other board to pinpoint where the fault came from and narrow the job.
Once found some abnormal output voltages you may look the following parts for defect.
1. Open fusible resistor.
2. Shorted transistor.
3. shorted diode
4. Leaky/dried capacitor.
You have said that you've already tested the capacitor in the board. But you have to test it not in the board, meaning you have to pull-out it to avoid reading the resistance parallel to its line. If you are using the ohmmeter, upon testing the good capacitor will charged(will have a reading of low resistance and back to high resistance depends upon the capacitance) and discharged gradually.
While bad capacitor will show the following.
1. will have a slow charging and very slow discharging
2. will not charged at all.
3. will charged and gradually discharged and again will charged but this time will not discharged...
