when tv is "cold"make the samsung startup noise, then screen screwy
EDIT: media added. Didn't catch the sound glitch, but caught several variations of the video glitches and restarts.
I have the same model
I got the tv because originally it was clicking and not starting up. I replaced the necessary capacitors to fix that issue. It worked for a few months and now I am having this new issue on startup.
Seems to be when tv is "cold" it will make the samsung startup noise, then screen will look screwy. Usually darker, mostly black or green, and the speakers emit a horrible max volume screeching noise. During this time you cannot power off tv or anything...it will do this for 10 seconds or so then shut itself off. It will then restart itself. It usually takes 2-3 restarts then it will startup without the noise, normal color and no weird lines and all is well.
I'm open to and capable or working on it again, just need to know where to start.
What specifically do you need from me to post to help zero in on the problem?
