hi friend, you have to measure hoy many volt. run along that line where the filter goes, what's the tv chassis number.
Good evening, if you're referring to the chassis PSW29UTA, which can take as reference the chassis that does have publications of diagrams, the PX20172, the condenser C487 according to the diagram you mentioned, is of 6. 8 ?F but the voltage is cleared, anyway, is hard to find chinese chassis diagrams with a hundred per cent true information. This condenser is not a commercial one, but actually, many of those values that usually come in these devices also do not come, what you do is to connect two electrolytic condensers in such a way that it becomes in non polarized.
