Good afternoon sirs I need to recycle a TV power supply with an output of 19v 2.65a, pass it to 12v 5a, I was told that with some components I could, but although I have manual skills I do not have much knowledge of electronics. Recycle a 32 "lg screen from a Grundig and I bought an Aliexpress controller card passing the features to the manufacturer, I bought an iverter compatible with that plate and I want to use the original TV source to feed everything since it has power to the inverter and 19v 2.65a I want to convert. For the inverter to work I know that you have to connect to the main that I bought to activate it when the card is turned on. The subject is that with a source of 12v 2ª I have the probe and everything works, but the backlight flashes a bit and as I was told it could be due to the lack of power given by the source I am using. Many thanks for your advice The source I have to recycle is a ZGN194-03 from a grundig that fed a main VKT190R-4, the latter burned and did not compensate me to buy replacement. source.jpg [301.24kb] aHR0cDovL2Nkbi55b3JlcGFyby5jb20vdXBsb2Fkcy9kZWZhdWx0LzAwMDEvMTcvcHJpbWFyaW8tNDM3MDcuanBn] ​​ primario.jpg [338.65kb] [url=/ver-adjunto/aHR0cDovL2Nkbi55b3JlcGFyby5jb20vdXBsb2Fkcy9kZWZhdWx0LzAwMDEvMTcvc2VjdW5kYXJpby00NjQzMi5qcGc=] secundario.jpg [308.60kb] I already found how to upload them. a greeting

What he pretends is not viable for the simple reason that he violates the laws of thermodynamics. You can not take more Watts out of a device than you initially have. 19V X 2.65A = 50.35W 12V X 5A = 60W In these two equations we see clearly. If we could pull 60W from a source that has 50W we would have the greatest invention of the entire millennium. The most comfortable option is to find a PC power supply and use it for 12 volts.
