    Prima PH42T7 - No Power

    Hi
    I am looking at at Prima PH42T7 that has no power/sound or LED, although I know it is drawing current. No relay clicks or pops in the audio when the mains are connected. I have not yet found the service manual for this one, but from the test point voltages on the PCB's I get nothing but millivolts in the dc range and around 2.5v AC instead. Anyone seen this or know if it is just the rectifier?Anyone know how to get the error codes to flash(although no LED) Any insight or links to the manuals would be greatly appreciated. Like other posts I have seen about the Prima, the boards are samsung and show no signs of damage or bad components and the TV has never been abused or dropped, just died one day.I could go and trace the entire circuit and look up every part#(looks like a week long job) and figure out a bit of the problem but I am somewhat new to the modern tv's, and am learning fast, any help would be greatly appreciated
    Thanks
    Dave

    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...

    Microsoft Surface Pro (5th gen) model 1796 - no power
    by PantherDave
    Hi all!

    I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

    I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

    Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
    by sam_sam_sam
    I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

    One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...
