"Pensonic"?? this is a plague.. it remains "Penis-onic"..
My guess is that these type of faults generates by oxydation on a certain part, before i was suspecting tcon circuitry, after some tests i think different , the degraded part is within the panel, (we can talk about this maybe later..), now the important is that circuit has more resistance than factory product, for the ohm's law you have to increase slowly the VGH to get rid of it until the pixels gate triggers to lit and bright colour.. if VGH is not enough maybe also VDD must be increased.. this is probably...Last edited by Davi.p; 02-11-2025, 02:33 PM.

Yes EDiD data are associated to hdmi and stored in some eproms near the connector, sometimes are integrated in other chips, but the LAN input can carry high current spike with arcs to surrounding components..
my curiosity to other users: am i the only one with the obligation of entering a Captcha code every post i put?

tvboy, the problem here is poor solder, this why Samsung put the glue on the most delicate part, the oscilator circuit and feedback circuit, you can start resolder the most important items.. transformer, power diodes/transistors.. this is my guess..

So the test point is connected to the Mountain or valley (lcd panel)

Don't listen to certain stories, VGH VGL are normal supply lines and the output of a normal dc dc converter..
can you show where did you do this "cut"? I see only a missing diode..

are there 8pin eproms near the hdmi connectors? or a small ic for each? them can be faulty..

was the ethernet cable connected usually? It can happen.sometimes the spiike runs through the lan cable and destroys the miniature transformer near LAN.connector..

disconnect everything from hdmi and test.. eventually inspect inside hdmi ports or check their pins with continuity check for shorts

check the power board if it has a microcontroller, it is maybe damaged or planned obsol. inside..

Oh my god... that's incredible..
1) i see what the user shows me, i saw 2 boards on picture, i thought it had only 2 boards also because of the 2 Twins lvds ribbons output, i cannot know every hundreds tv models in the world! User Diah must calm with its words, i have never hamed a tv.
2) It's fool to dismantle Cyclope's tv for the doubt of bad backlight, and i do not see any sign of that, much more safe and easy to do the test i have already said, 2 minutes test!
3) I have never seen in long hobbist career a tv set that enables tcon power but not tcon input data due to bad BL...Last edited by Davi.p; 01-17-2025, 11:40 PM.

basically, if you find a log error, example a file not found, error in file, and partition failed to mount, always same error, then software error and stop, if the errors vaires , then failing BGA...
