Finlux 50F8075-T flicker

[sniktaw]

Have a regular flicker across the full panel on any source per the video here: https://youtu.be/dx0vBQTk2VE

Is it likely to be the T-Con, PSU or something else?

Many thanks in advance, Darren.

maybe bad connection in the backlights.

I would say t-con or panel issue

Ah, I didn't look at the video, yes I think you are right Dskall, maybe check the little ceramic caps on the panel driver board, tape cut-off method may work.

something to try whenever you have this double image thing is lighten the load, turn off all the video enhancement crap, ambient light if equipped and all that other crap, turn down the backlights, NOT brightness and see if the display changes any.

Thanks all, plenty to try. Much appreciated ;o)

Re: Finlux 50F8075-T flicker

Great news - fixed! Issue isolated to left side of screen by disconnecting t-con ribbons. Used tape cut-off as suggested by nomoresonys to block clocks and all is good ;o)

Also noticed a bad cap on the PSU so will replace as preventative measure.

Thanks guys.

Glad to hear it, you don't suppose that bad cap was causing the whole problem?

Could be I guess, Caps should be here Saturday so I'll try and report back. Either way I'm a happy fella!

Re: Finlux 50F8075-T flicker

Replacing CAPs had no effect on flicker.

Thinking of replacing t-con board as I can get one for £10. Board is an LG part: LC500DUE-SFR1 per photo.

Are they model specific? Some listings show for 42" TV, 50" TV, etc with usual caveats that part will only work on that TV.

thanks,

Darren.

If blocking lines fixed the problem, then you have a panel problem not a t-con problem.

Re: Finlux 50F8075-T flicker

Ok, thank you. Every day is a school day ;o)

Can I do anything about the panel problem?

If you now have a good picture, you have fixed the problem.
