    PROBLEM WITH AN HP DV2000 SERIES; MOTHERBOARD: 440768-001, SHIBA 05234-4


    PROBLEM: COMPUTER FAILS TO POST TURN ON COMPUTER THERE IS NO SCREEN ILLUMINATION. DO NOT FEEL THIS IS A GRAPHICS PROBLEM (SEE bELOW)
    NO HP SPLASH SCREEN
    NO WINDOWS SCREEN
    FAN RUNS
    POWER LIGHT ON
    ONE QUICK FLASH OF HDD LIGHT OCCATIONALLY

    CORRECTIVE ACTION TAKEN
    THREE REFURBISHED MOTHERBOARDS
    SUBSTITUTED FOUR RAMS
    FLASHED BIOS ON ONE BOARD AND UPDATED
    REPLACED BIOS BATTERY
    RESET CMOS BY BATTERY REMOVAL
    RAN ON POWER ONLY
    RAN ON BATTERY ONLY
    REPLACE HDD
    REPLACED HDD DRIVE TO MOTHERBOARD ADAPTER
    TRIED TO LOAD WIN XP FROM STARTUP
    PRELOADED WIN XP FROM OTHER COMPUTER TO HDD
    CHANGED CPU
    REMOVED ALL PERIFICALS
    RAN MOTHERBOARD OUSIDE OF CASE.
    CHECKED CONNECTION FROM MOTHERBOARD TO SCREEN
    REMOVED HEATSINK/FAN


    SUCESSES
    ONE QUICK FLASH OF HDD LIGHT OCCATIONALLY
    ON TWO OCCATION THE COMPUTER WENT TO HP SPLASH SCREEN AND THEN TO WINDOWS. AT THAT POINT LOADED BIOS ANS DRIVERS. NOT SURE IF DRIVERS ARE IN THE HDD NOW RAN COMPUTER FOR ABOUT 15 MINUTES BUT HAD TO BOOT FOR BIOS AND DRIVERS. THEN NO SCREEN ON START

    ANALYSIS
    DONÂ’T FEEL THIS IS THE TYPICAL GPU PROBLEM BECAUSE OF THE TWO SUCESSES AND SCREEN ACTIVATION
    THERE IS SOMETHING I AM MISSING AND HOPE THAT IT CAN BE IDENTIFIED BY MEMBERS OF THIS FORUM

    almost sounds like a short. have you ever tried running it dismantled with the motherboard on a wooden table and just run power and the LVDS cable to it?

    Have you attepted startup with an external monitor? Perhaps a short in the LCD invertor board?


    (just throwing out a possibility... I'm no "tech")

    Well, it appears the Caps Lock works! :eek:

    Sorry, couldn't help myself...

    Check the cables/connections between the LCD and motherboard. Remove everything you don't need (HD, LAN, all but one stick RAM) to eliminate possibilities.
