Hi
When there is no datasheet, check this link, use the same integrated one that you want to use, compare with your TV. https://yoreparo.com/tv/televisores/tubo/preguntas/1431277/el-tv-no-enciende
The STRW67XXX cannot be replaced by the STRW65XXX or vice versa, as a replacement for the STRW6735 you can use the STRW6753, STRW6754, STRW6756, STRW6757
Thank you both for such quick responses. For example they are not compatible, in fact, mount it (STR W6553A) and at the time of connecting it begins to activate and dismantle intermittently the relay of the source. The screen never turns on. Which gives me the conclusion that this regulator does not support the consumption of the card. Thanks and happy day!
