  • Re: Use DC Power Supply to Test LCD TV???

    I was hoping to first test the standby electronics separately by powering the 5V harnesses, then try the 24V separately in the same fashion, then if both work, borrow a smaller power supply to power both at the same time. Does the 5V rail scavenge off the 24V when the TV us powered on, or is that a dedicated source for the uC's, processors and such?

    Is the 8Amps a power on current caused by the ballasts? Or a full time current? I guess ~200W sounds reasonable... scary. Maybe I can hook it up to a couple of lead acid batteries?...

  • Use DC Power Supply to Test LCD TV???

    Hi all, I'm not sure what the heck is going on with a TV somebody gave to me recently. Everything *looks* fine except a couple of suspect solder joints. I was hoping that I could hook this TV up to my DC power supply to see if the rest of the TV works before wasting time working on the power supply.

    The TV is an Insignia NS32LCD. Uses 5V sleep and 24V powered on.
    The DC is named MPJA 15601 PS. It's capable of 30V and 4A.

    Any idea what this TV might draw current wise? I'm a little worried about the power-on current spike, tho it's probably reasonable.

    OPTIONAL READING: Hi all, this is my first post to this board. I had a NS-32LCD given to me today in no certain condition. It feels like good karma since my 42" Toshiba, tools and all my possessions were recently stolen from my storage unit during some travels.
    Figuring if it didn't work it'd probably be the power board or a fuse and an easy fix, I gladly took it. After doing tons of reading and research on this website and others, I decided to tackle the job.
