It should be soldered. Can you still see the solder pads on the board?

Yes, and the piece has two wires coming out of it... Like it wasn't soldered well or at all...Comment

Re: LG 60PX950 No video...
I've had them break off on my boards that I don't store properly. I would suggest you solder it back on. Given the rarity of the board I don't think you can really return it but you might be able to get a discount/part refund.Please do not PM me with questions! Questions via PM will not be answered.

Re: LG 60PX950 No video...
I fixed the cap, and the TV has been working fine until this week. Now it will lock up occasionally and restart on it's own, image freezes and it has to be turned off, or it will start artifacting like crazy.
If I turn it off and back on, sometimes it does what it was doing previously, not display anything on the screen. However if I leave it turned off long enough it will start working again (displaying an image).
Any thoughts at this point? Could it be another component is affecting this main board at this point and causing it to fail? Perhaps bad voltages from the power supply or something else?
Thanks.Comment

Re: LG 60PX950 No video...
If possible, perform the Ext Auto Gen test for a few hours and observe that the TV does not freeze or lock up (just check occasionally.)
Some sellers don't thoroughly check their boards, so this might be a good time to use any warranty they offer before it expires.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: LG 60PX950 No video...
I'm having a similar problem. My 60px950 hdmi inputs stopped working, but the rest of the inputs work such as the USB for the wireless card, the RGA and red white and yellow component cable, but none of the hdmi ports.
Do I have to replace the entire input board or is there a capacitor or something that went bad on the board itself that would knock out the hdmi ports?
I just know enough to get my ass kicked about this stuff, so please go easy on me.Comment

Re: LG 60PX950 No video...
I've had the LG 60PX950 for around 5 years now and for the past 6 months, I've had two issues. The first one that came up was that all digital inputs (hdmi) stopped working and the tv kept displaying the no signal icon on all the hdmi inputs. The second issue that came up afterwards was the screen only working intermittently. The screen would only work for about 5 minutes at a time before it went completely black. In the past week, I managed to find a replacement main board on ebay. Just last night, I swapped out the main board with the one I got on ebay and the hdmi ports began working again, however, I still had an issue with the display only working intermittently. Since my dad always thought heat was the issue, we decided to blow a fan on just the ZSUS board and the display worked without any issues leading us to believe that there was some sort of heat issue with the ZSUS board. I just ordered a ZSUS board online and will install as soon as I get it and hopefully, the $2,000 tv will return back to working condition! If not, I might need some feedback as to what else could possibly be wrong :/Comment

Re: LG 60PX950 No video...
So I've replaced the main board and the ZSUS board and at this point the tv still doesn't want to work like normal. However, the screen starts working again every time I press the small black reset button on the small board to the left of the large main board. Should I replace the board with the small black button on it or the one to the left of that board? And advice would be greatly appreciated!Comment

Re: LG 60PX950 No video...
It's a capacitor and it should be easy enough to solder the two tab legs back onto the pads. Just make sure you have it the correct way round.Willing to help but I'm no expert.Comment

When I select the FM receiver, I find a radio station, the sound is heard on REC OUT(L,R), REC TAPE1(L,R),REC TAPE2(L,R) on high-ohm headphones, the sound regulation does not work.
The output reacts when I connect the record player to PRE OUT FRONT L, the sound is heard in the speaker but the sound regulation does not work. Then it does not matter what I chose on the front selector.
I replaced the capacitor C303/0.047F, nothing changes.
I'm asking for help, what should I do next?
Thanks in advance!... -
I am working on a Samsung un55cu7000d which has backlights and audio. There is no picture. This model does NOT have a separate TCON board. Before I order a main board I would like to try and confirm that the issue is not in the display. The ribbon cable from the main board goes directly to the display and I can then disconnect the left from the right. When I disconnect the right side the display lights up on one side but has no video being displayed. Can you all give me some guidance on how to confirm the main board is the issue. -
Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds
- it keeps rebooting
- without ribbon cable between the two panel boards, it does not reboot but I have no picture
- without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
- when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.
- without cable between mainboard and lcd panel and with a jumpered... -
I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -
Hello everyone,
Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
Anyway I still fully expect that there has been something seriously damaged...
