Could Top247Y IC Substitute For Top246Y?

By on May 15, 2008


Came in a Samsung 713n 17″ LCD Monitor for repair and the complain was no power. After checking the power primary side found three components that was faulty the power IC top246y, a 15 volt zener diode and a signal diode 1N4148.  Secondary components found to be okay. A search at my spare parts compartment could not locate the TOP246Y power IC thus i just gave it a try on the Top247Y power IC. Guess what? It worked perfectly good and now is under burning in test.

If you are repairing LCD Monitors, please take down this substitution part number, who knows one day you might have need it. Have a good and a happy troubleshooting day!

    Thanks and this is what we call as power of sharing. In fact i wish that more readers participate in sharing out tips and whatsoever that is related to electronic repair. With this sharing, everyone will learn even with just a simple comment! If you have read from the spec it seems like the higher number can be use to substitute for the lower number.

    You see, not everyone is good in locating schematic diagrams, spare parts, datasheet as some of the websites was buried far below the search ranking. If you have bookmarked any and wish to let us know about the websites, i strongly suggest you post a comment in my blog. I'm really happy about it. Thanks again my friend!

    HI Swapnil,

    Try check all components in the primary side and if all tested okay then direct replace the power IC and retest it again.
