Samsung un65fh6001 issues

[Cschares87]

Hi I received the TV and trouble shot it down to the back lights. I replaced the led back lights and everything was good. I turned it on it worked great. After I put the bezel and the case back on and turned it on again all I get is vertical colored lines. I checked all the ribbon cables and everything is fine. There is a picture attached of what I get now. Any ideas on what causing this? Thanks so much!

Sorry I thought I attached it. Here it is

Did you flick up the tabs on the tcon connectors to remove the flat ribbons and then pressed it back down into place after re-inserting the flat ribbons or have you just pulled and pushed the ribbons in/out of the connectors?

Re: Samsung un65fh6001 issues

Yes I reconnected the ribbons on both ends to make sure they were connected properly.

If you pushed the ribbons back in then the gold connections on the end may be damaged.

If you disconnect one ribbon from the Tcon and then power up what do you see on the screen.
Power back down and reconnect the ribbon and disconnect the other ribbon from the Tcon to panel and again see what you get on the screen.

yes but did you do this as suggested or did you pull/push the ribbons into the clamps without releasing them?

further, did you use your glasses when working with the ribbons to ensure they are aligned properly... :-)

Lastly, check the bezel / frame area near the edge boards to ensure there is no metal pieces contacting the boards anywhere. You had the power disconnected when you were putting the bezel back... right?

actually, looking at the picture closer, you lost the leds again. somewhere in your "re-assembly", you caused an issue with the panel connections. since you are familiar with the leds (having replaced them), check the connection going there first to understand why some appear to be gone again. If you are lucky you might find some "localized" issue / connection there. Related to this is how were you manipulating the panel while the frame and bezel were off?

Re: Samsung un65fh6001 issues

I ordered used LED strips from eBay and I'm pretty sure one of the strips wasn't good when I tested it but wanted to make sure everything worked ok. I think when I was lifting the TV up I may have damaged the ribbons because I did it by my self and it puts a decent amount of pressure on the bottom of the TV when you lift it. I'll try the removing one strip than the other here in a few mins.

Re: Samsung un65fh6001 issues

Yes I had everything off when I assembled it. I also pulled the bezel off when I was checking the ribbon. I also reconnected the ribbon multiple times and tried it to make sure it was connected correctly. Thanks for the help guys though I really do appreciate it!

Re: Samsung un65fh6001 issues

Here are the pictures from having one side of the tcom ribbon removed. It looks like that's the issue. But how do I fix it? Thanks.

Re: Samsung un65fh6001 issues

so you need to really really look at the ribbon cable on the "bad side" (ie. vertical lines).... those are indication that no / little signal is getting to the panel through that cable OR thru the edge board that it is connected to. The other possibility is you caused an issue with the edge board... you need to check some of the SMD components in the edge board (capacitors / resistors) to see if they are OK. IF you are lucky, although the board itself can't be replaced, a careful soldering job can replace a given component while the board is still attached to the panel (because it can't be removed).

My guess is you do not have the cable set properly in the clamped connector, either the pins are misaligned or the cable traces are damaged.

Re: Samsung un65fh6001 issues

I tried the ribbon cable 30 different times. I took the ribbon cable from the other side and tried that to make sure it wasn't the cable. Still the same result. I looked at all the components, couldn't find any broken ones or damaged ones. Any other ideas? Thanks!

"looking" at components ain't a good method... it like looking at a woman... you need to check them with a meter.

LMFAO


but on a more serious note. it looks like the panel may of received some damage when you worked on it and i'm doubting that it will be repairable.
seen lots of accidental panel issues doing backlights unfortunately.

Re: Samsung un65fh6001 issues

You've detached part of the leftmost tab bond, you miss now of the vertical informations, there is a very thin possibility of repair it, check youtube on "soldering lcd without bonding machine", something like this..

Wait, what? You check your women with a meter? Does that work? Is this what I've been doing wrong all these years?
