    Default Gundam pachislo slot machine Screen not working

    Hello Everyone,
    So I finally come across one of the best looking machines in my opinion and the sceen is not working. I noticed that a lot of these gundam machines screens stop working from what I have seen for sale. Does anyone know how to fix this. I have unplugged all of the plugs and plugged them back in but its still the same thing. I do not think it is the video card becasue the screen lights do not light up so I am thinking it has to be the monitor not the video card. So if you have a screen or a video card for this mahince or an idea on how to fix this machine I would be very thankful.
    Thank you and have a great day.

    Hello Eveyrone

    Have you ever had a machine that you really want to fix but it is kicking your butt all the way. Well Hello GUNDAM Pachislo.
    anyhow so here is my progress so far.
    so it appears that Aliexpress has the screen for sale but does not have the screen for sale. Meaning they are advertising it but do not have the item and can not get it but they did take my money and will not return my emails. Oh why does this gundam machine hate me so much. I also called surplus traders today fingers crossed that they had the item and they can get it but I have to buy a crate of them of 60 units. So that is not going to happen. So does anyone have any more ideas. or any parts you might want to sell. Thank you in advance and I hope everyone is doing well.

    Problem Solved

    Solution: LCD inverter Bad, Repair involves soldering 4 wires to LCD circuit board

    Purchase new Universal CCFL LCD Inverter from Ebay. $2.95 to 5.95 price will vary

    DO THIS REPAIR AT YOUR OWN RISK

    If you are familiar with soldering electronic parts you'll easily be able to do this repair.

    This is the part you will need from eBay.

    Screen will plug into the backlight connector with some modification and the 2 wires get soldered to the power and ground on the inverter board. Then solder those wires to the old LCD board at the power and ground leads that are before the burned out inverter.

    Reassemble and power up, the screen will now be working.

    This repair can be performed on any dark screen on any LCD.

    Hope this helps anyone. My Gundam now works beautifully again!

    Hello, I've purchased the inverter but I'll admit that I'm not very electronic savvy. Is there anyway you can either post or PM me pictures of your set up installed into a machine?

    Here is a simple pic guide to replacing your LCD inverter.

    Before starting test your LCD to make sure it is getting signal. Shine a bright LED flashlight or your cell phone light into the screen to see if there are graphics displayed while the machine is on. Look closely the for image will be dark and hard to see. If there are moving images your graphic card is fine if not replace the graphics board.

    Follow the pics as an example all LCDs and inverters are different but all operate on the same principle. This is a trial and error process so don't get discouraged.

    SHUT MACHINE OFF

    OPEN THE BACK OF THE LCD CASE
    20170303_163020.jpg

    TURN MACHINE BACK ON

    TEST WIRES FOR CONSTANT VOLTAGE AND IDENTIFY THEM
    20170303_200055.jpg

    TURN MACHINE BACK OFF

    CUT WIRES TO LCD BACKLIGHT
    20170303_163247.jpg

    OBTAIN 2 WIRES AND SOLDER TO INVERTER BOARD 1 TO VIN ! TO GROUND
    20170304_001849.jpg

    CONNECT THOSE 2 WIRES TO THE POWER SOURCE WIRES YOU IDENTIFIED
    20170304_001629.jpg

    OBTAIN 2 MORE WIRES AND CONNECT THEM TO THE INVERTER OUTPUT AND THE OTHER END TO THE CUT WIRES FROM THE BACKLIGHT
    20170304_001702.jpg

    TURN MACHINE BACK ON

    OBSERVE LCD IF IT LIGHTS UP

    1- LIGHTS UP, YOUR REPAIR WENT WELL SHUT MACHINE OFF AND REASSEMBLE
    2- DOES NOT LIGHT UP, REVERSE WIRES TO BACKLIGHt. IF IT LIGHTS UP YOUR REPAIR WENT WELL SHUT MACHINE OFF AND REASSEMBLE
    DOES NOT LIGHT UP, REVERSE THE POWER INPUT WIRES. IF IT LIGHTS UP YOUR REPAIR WENT WELL SHUT MACHINE OFF AND REASSEMBLE

    IF IT STILL FAILS TO LIGHT, YOUR CCFL BACKLIGHT TUBE IS BURNED OUT

    If your backlight light is burned out there still is hope for a repair. The CCFL can be replaced inexpensively.
    Here is a link to how it is done. (this is not my video)

    https://www.youtube.com/watch?v=smrMoIpvYTk

    The replacement LED strip can be purchased off ebay. Here's a link to one, just search CCFL LED Replacement Kit. Choose a kit for it contains the power source, led strip and all connector wires.

    http://www.ebay.com/itm/330mm-LED-Ba...QAAOSw2gxYrpTb

    Here is another video on how to do the CCFL replacement. (again not my video)

    Good luck on your repair!
