    I can swap the 2 boards from one panel to the other or mix and match the 4 board in any combination with the 2 panels and there respective ccfl's and the problems follows the inverter boards. So as far as i can tell the bulbs are good in both panels, and the lcds are both good.

    The good news is i just got an email from a free cycler that i can pick up an unknown brand 19"er that just went bad the other day for FREE and its just done the road from home.
    Hello again dmbj
    With what you said in this post I agree with you on the good CCFLs and LCD panels, so it looks like to me with help from Eguevarae that the white panel may be a fault with the 5v rail on that Inverter/P Suppy board,
    and the inverter on that board seems fine because you have B/Light

    The other Inv/PS board seems like its still your Inverter by what you have said

    So i would compare voltage outputs on both boards with M/meter to search for fault in 5v rail by comparing readings

    And search both inverters with continuity and resistance (not powered up obviously) so as to find the fault in the bad Inverter

    ( thats my suspicions ) hope it helps, with the free cycler and patience you may get 3 working monitors, Good Luck

        Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
        by Tynan Dill
        I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

        Upon bringing it home and plugging it up, it showed a standby light.

        I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

        The screen seems to blackout and stay black, but with a flashlight I can see the display.

        With my Playstation 4 connected via HDMI, and running a game I can hear sound.

        Assuming...

        Macbook pro logic board replacement parts quesion
        by boosti45
        i have a 2020 macbook pro 13" A2251 with 820-09149 logic board so i found an issue with chip labeled U6903 according to schem. boardview using flexBV software, so i removed it from the board and the issue im having is that the chip says "07A08FI ELC180​" on top of it but when searching for a replacement chip, i can find tons of identical looking chips that also have "ELC180" printed on them but the first set of digits is never the same so im trying to find out if i need this exact chip with these same numbers as mine and if not which ones are compatible as a replacement?...

        Power Inverter Replacement Circuit Board Question?
        by jdbird613
        So my Ampeak 2000 watt power inverter will receive power from a 12 volt source, and also has a display screen that displays how many volts the inverter is currently using...However, the plug outputs are not producing any power outward...The display screen on the inverter also shows how many volts an item that is plugged in is currently using...Which stays at 0 and no items will power on...I opened the inverter casing and discovered there is some charring and burned areas on one end of the circuit board...What I am trying to figure out is if I can purchase/obtain a new board exactly like the board...

        Philips 65PUS8518/12 distorted image after main board replacement
        by tuner2000i
        hello everyone,

        I don't normally do tv repairs but this is a case with my personal TV which got fried together with many other electronics in my house after a thunderstorm.

        The TV is a Philips 65PUS8518/12 which had no power. I measured and concluded that the main board was probably fried through ethernet or hdmi. I found a board with same number 715GD328-M0F-B00-005Y (I had G) but from a 55PUS8518. The TV starts but the image is doubled, distorted. I need to set the panel code which is 016 according to the sticker on the back but I can not seem to do it.

        ...

        Looking for help with a Viewsonic VP230mb where the backlight comes on only momentarily
        by lostone
        Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

        First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
        When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...
