TV wouldn't start, when you turn it on, it just stayed on standby | TV went into protection. I thought it was a regulator with a 9v start, but it was fine. Removed the protection and nothing. | Until we decided to measure the 1000/16v c 826, it had very low capacitance, it supplies power to the 9v regulator, it supplies 10.5v, with the TV replaced. | <small> |
