    No not really. You can download the schematics of the board and measure every single component but that takes a lot of time.
    I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!

        Probably shorted Ic then best just to replace the board.

              Requesting Help For GA-970A-DS3 rev. 1.0, No Post code, no RSMRST# signal
              by AstutePauciloquent
              Hi everyone, over the past few months i have taken a deep dive into motherboard diagnostics and I love the challenge. Currently im trying to learn all about the signals that travel around the motherboard, such as frequencies, enable signals High and Low logic states etc. And i have been learning to read and using the Schematics for this board that i requested here on Badcaps forum, from a few months ago, this is such a great place for these.

              I’ve been working on a GA-970A-DS3 (rev. 1.0) that does not post. This motherboard has been my main learning board. I would like share...

              Vizio M65Q7-H1 Red Vertical Strips fixed by tape blocking LC1 signal to half of the panel
              by howardc64
              Failure Symptom



              No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.

              Where is the short?

              Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.



              Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but...

              Sanyo DP55441 - No brightness control
              by karthur
              Recently picked up a Sanyo DP55441. Set has a few issues:
              1. When I turn it on, I always have to select either "Store" or "Home" on the menu (see attachment).
              2. It forgets which input I was using last, so I have to change the input setting everytime.
              3. The controls for Brightness, Contrast, Saturation, Hue and Sharpness are not available from the menu (see attachment).

              Besides these issues the set works good, no other issues that I know of.

              I am thinking all three are related and its probably the main board. I have looked...

              Converting +/- 5v to a Usable Hz Signal
              by JayPoorJay
              Good morning.

              I have posted here before and have gotten AMAZING advise (thank you!). I'm back for more. This BCaps Sub Forum is so well attended I thought I would post here.

              This question is for an automotive application but has to do with what are essentially electrical questions and problem solving... If this is inappropriate I get it. Feel free to delete it or move the question.

              The V 12 Jaguar XJS is notorious for overheating in stop and go traffic in hot weather... Y'all will be potentially helpinh a LOT of people. The solutions and directions...

              What is a normal composite signal range for a C64?
              by Scruit
              Hello all,


              Working on my first C64 / Breadbin / 250407. Purchased as non-working. Getting black screen.


              More detail below, but for those that want to get right to the question.... Here are a few waveforms comparing the Pin15 output on the VIC chip (luma/sync) to the pin 4 on the AV socket (composite signal).

              https://imgur.com/gallery/PpqcqPY


              My question is: Is the composite waveform range of 0.1v-1v too low for a c64?



              More detail:


              Symptoms are that that I get...
