    Zenith SR2049DT CRT Inputs Not Working

    I tried to add analog RGB inputs to my CRT so I could use my European Amiga and my Atari ST on the same television. I thought I had everything mapped out and just right but when I plugged in the set I heard a crackling and popping sound. Then I smelled burnt components. On the jack board 4 resistors were blown and one cap looked suspicious so I replaced all of those and totally removed the modifications I had made.

    Sound input works on the white audio jack but I get nothing through my coaxial antenna input or my composite video input. My OSD still works though and I do get snow over the tuner.

    I don't see any other obviously damaged components so I was hoping to get some direction on what may need to be replaced.

    I have included the service manual in pdf format.

    Thank you in advance.

    [Troubleshooting] Dell T7610, computer won't post after turning on memory mapped IO >
    by elzorroazul777
    I have a Dell Precision T7610, 2 Xeon 2650 v2, 128Gb of ram, MB NK70N. Bought off of ebay in December and shipped with 1 processor and 64 gb of ram. I recently filled the other side of the board with processor #2 and 64 more Gb of ram. There are two gpu's, Nvidia K420 for video and Nvidia P40 for accelerated graphics. I have shelled out my entire budget on electronics tools and building this β€˜homelab' computer. I do not have the money to buy another motherboard at this time, otherwise I would!

    The motherboard that shipped with the computer needed replacement as socket #2 wasn't...

    Zenith Z50PJ240 - White Screen with 'Power Only' displayed
    by cmonkey
    Turned on my lovely plasma and after about 30 seconds the screen below showed up. None of the inputs are responsive, just the red light flashes when I push it. Remote doesn't work either. To turn it off I need to unplug it and when I plug it in again it turns back on to this screen.

    I only found one reference to this issue with a different model but it didn't look super reliable. Only mentioned a 'main board fault'. The main board for this one is on ebay for $34 so might need to go with that.

    Anyone seen this before?

    Thinking about it some more, it happened...

    Inputs & Outputs to MJM2068MD-TE1
    by DAVEMAC02
    I'm trouble shooting a bad channel in a portable pa system. I suspect a dual OP amp is bad in one section. I want to signal trace the output of the B amp with an old Radio Shack audio signal tracer but don't know if this is feasible and won't cause damage. Thanks

    Why are there two inputs mosfets?
    by mikay786
    Just trying to fix this old Alienware m14x laptop.

    found a shorted capacitor and a shorted mosfet on the input mosfet pair.

    im i newish to this and was wondering why you almost always have a pair of identical mosfets on in the input? They both do the same thing so what the point?

    also on a side note i am eager to test laptop since no short now, is there a way to bypass the 2nd mosfet for a temporary solution until replacement arrives?...
