Hello everyone,
Before getting to the problem, I am not an electrical engineer by any means but I really want to learn component level testing/trouble shooting and I do my best to pick things up quickly, that being said...
I have a Magnavox 50ME314V/F7 (the Model of the boards are "BA4GU5G0201 2". The power board beeps when it is plugged in and when the CPU board ribbon cable is plugged in.
I have replaced the 2 components with the red stars in the attached photo "PB TOP - Full". But it still beeps when powered and connected to the CPU board.
I am not sure which diode is emitting the beeping sound (I assume the beep happens when a diode gets stuck open or there is a short). I also can not find any schematic or service manual for this model tv. I do have a DMM and would be happy to post any test results that you guys think would be helpful to help me diagnose this issue.
I am attaching photos of the Power board (PB) and the CPU Board (CPU).
Thank you all for any help or insights you can provide, I really appreciate the help and the ability to learn something I have been interested in for a while.
