    Help to find cheapest 12V/5A power supply

    I have a THOMSON 24" LCD TV that works with an external 12V/5A (in fact 5.2A rated current consumption). The CHINA-made smps I bought with it just literally burned after a few hours of continuous watching. Any cheap do-it-yourself design of such a SMPS?? A 12V car battery is not a good solution.

        Nothing, just scrap an old PC or find an old laptop power supply and put a few 12V regulators across the output of it.

                xbox 360 psu with ps on tied to +5stby.
                tie all yellows together including the thin one.
                thats +12
                tie all blacks together including the thin one.
                thats -
                the thin leads are remote sense.
                tie red and blue together to turn it on.
                overkill but probably free as the consoles are all junk now.mine all have anderson powerpoles on them.
                i run a 100w hf rig with one.

                  Yep, a PC PSU should work perfectly even better than the original just a bit louder but nothing to be worried about
