    Troubleshooting tube cameras

    I picked up a Panasonic WV-200P "TV Camera" and to my delight within it was a Newvicon tube. In fact, it's the exact same tube I bought as NOS.



    My problem is that I'm getting no video output. Even if I cover the lens the image remains on the screen: white with 10% of the left fading to black.




    I'm pretty sure this isn't the fault of the tube otherwise I would of seen something happen when I covered the pickup and I'm pretty sure this is not the result of me removing the newvicon and putting it out of alignment.
    The rest of the camera consists of two boards and discrete transistor logic.
    Did I also mention that tehre are a BILLION capacitors? It outputs to 79 ohm 1Vp-p which I believe is just composite.
    Find Nedry!


    Check the Vending machines!!

    B&K 707 tube tester. I need help.
    by DCJack
    Hi everyone!

    I managed to get my hands on a rough condition B&K 707 for "the best price" because it was not working. It's my first tube tester and I'm really wanting to get it up and running. I downloaded that manual that has the schematics and tested every resistor and capacitor and replaced the ones that failed. I replaced the missing 83 rectifier tube with a used but tested-good one. I also have a number 80 rectifier tube that I have used in tests before I found the 83 tube.

    Initially I noticed that I was not getting the red on-light to turn on, but it...

    practical courses for troubleshooting pc motherboards
    by blues_spirit
    Hello from France,
    mon2 kindly advised me to post a thread to ask the question(s) I'm concerned about. I'm new to the forum and I'm looking for practical courses for troubleshooting pc motherboards especially laptops in Europe, if possible in France. I have been a computer network system administrator and a corrector of administration modules for automated programs under Unix. But I really miss the practical "ops" side of troubleshooting. So I would like to start from the beginning: 1.8V, 3.3V, 5V and 19V tests for example, etc...
    Do you think this is feasible for me? I...

    ECH81/6AJ8 Vacuum Tube Question
    by Schoenradt
    Recently I acquired an Eico HFT 92 AM/FM radio made back in 1958. The unit has had some decent modifications done such as replacing the rectifier tube with silicon diodes and replacing the main filter capacitor with electrolytic capacitors. When I powered it up FM wouldn't tune past 105Mhz. I checked the FM tuner front end assembly and found a capacitor not soldered to the coil from the Plate B+ to and ground on the other side of the coil. Some calibration was needed on the trimmer capacitor on the tuner. My question is AM is extremely weak. When I tap on the tube I get all kinds of snapping and...

    GV-N2060OC-6GD REV 2.0 GIGABYTE video card troubleshooting assistance needed.
    by gcrezz
    The issue with this video card is the HDMI port. Specifically on pin 19 (Diode checks on all other pins are normal). When i do a diode check on it from the pin on the board itself, I have nothing. There is also no short on the pin. Resistance reads about 200k. Normally on any HDMI pin 19 I would expect some voltage drop anywhere from .5v to 1.2v but here, I have nothing. The card is operational and can be used via the displayPort ports, but not through the HDMI. Attached you will find the pdf schematics for the card on page 22. I have verified that all of the resistors on this line before the...

    Looking for assistance troubleshooting a Panasonic TC-P65ZT60 with 3 LED Fast Blinks
    by CrewmanRedShirt
    Hello all,
    As the title states, I followed the troubleshooting guide located here: https://www.manualslib.com/manual/23...page=53#manual, which concluded the 'A' board needs to be replaced. Looking around the net and eBay, I see that there are repair services for the board (TNPH1043UE? Not sure if it is a 'UE' as the suffix grid does not appear marked). What additional troubleshooting can be performed to ensure 1) this board is the problem and 2) since there are repair services, what are they fixing on the board?) I expected 3.3V not to be available anywhere...
