    Dell 2209WA - power supply - Fusible Resistor replacement
    by jinu_j
    Hi

    I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.

    1. FR950 - blown fusible resistor - 0.2 Ohm 1W
    2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
    3. R835 - Blown Resistor - 20KOhm SMD resistor
    4. D930 - Shorted Schottkey Diode...

    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...

    Vizio P659-G1 Screen Removal / Backlight Replacement
    by bstewara
    Hi All,
    Has anyone had the experience of replacing backights on the “P” series Vizio tv?
    Model number P659-G1
    This type tv has a very small bezel holding the screen in and I’m not sure how the bezel/screen is assembled. ( I’m hoping the screen is not epoxied to the frame)
    Before I attempt this I thought maybe someone on this forum has performed this backlight replacement procedure.

    Thanks in advance...

    Backlight replacement mess, Vizio V505-G9
    by giddyupngo
    Hello, I would appreciate your expertise on this. I have about 5 years experience with copier repair, so I have done a lot of board and component replacement. This is the first LCD TV I tried to repair, and it really humbled me. The issue was that on power on the TV power light would go on and then fade out seconds later, and there was no image at all, screen stayed black.

    I thought this meant there was a power board problem, not realizing that the power light fading out was by design, probably so the light would not distract the TV watcher. This is not my TV, so I wasn't familiar...
