Re: Samsung PS51E450 screen issue
One area looks like it's been getting really hot. I would check the components on the underside and all the solder joints in that area.
Have you tried running just the test pattern check.Attached FilesLast edited by dick_barton; 07-04-2020, 04:45 AM.Willing to help but I'm no expert.Comment

Re: Samsung PS51E450 screen issue
How do I get the test pattern check on?

Re: Samsung PS51E450 screen issue
Do a search on this forum to get the right info.
For many sets it's disconnect the mainboard ribbon to the logic board and jumper the Auto-Gen pins on the logic board then power up.Willing to help but I'm no expert.Comment

Re: Samsung PS51E450 screen issue
It seems to suggest that it's 1 & 2 shorted together and also 3 & 4 shorted together for PAL but I'm not 100% sure.Attached FilesWilling to help but I'm no expert.Comment

Re: Samsung PS51E450 screen issue
well, won't know unless someone tries it, so here goes.
So put the jumpers across and with the main (cn2023) ribbon cable disconnected power up, yes?Last edited by notallbad; 07-04-2020, 08:02 AM.Comment

Re: Samsung PS51E450 screen issue
Well, just a black screen with the sparkles (discharge) still.
But what I do notice now is 2 thin blue lines down the middle of the screen. Not looking good.
With the jumpers back off and main disconnected its just a black screen. Just for info.Attached FilesLast edited by notallbad; 07-04-2020, 08:30 AM.Comment

Re: Samsung PS51E450 screen issue
Try with just 1 & 2 shorted and CN2024 (if that goes to mainboard ) disconnected.
Edit
Is Ve back to 78V . If not this would need to be resolved. Previous posts on this model suggests a plasma screen fault, but you never know.Last edited by dick_barton; 07-04-2020, 08:50 AM.Willing to help but I'm no expert.Comment

Re: Samsung PS51E450 screen issue
Yh, that done it.
1 and 2 jumpered and main disconnected.
Screen white. blue. red, green etc ..
Would agree now, screen damage!
I believe this was caused by liquid damage, attempt to clean the screen possibly.
VE still jumping around like crazy!Attached FilesLast edited by notallbad; 07-04-2020, 09:02 AM.Comment

Hi all,
Because of two bright spots and a couple of dark spots I decided to replace the backlights in my Samsung UE48JU7000. See attached photos:
I thought all went well, but after full assembly and testing it out it turns out not all is fine. The backlights are completely fine but I have some weird issues on the right half of the screen. Since I didn't really touch the T-CON board (apart from taking out the ribbons of the display and reconnecting them on assembly) it would be weird that the issue is with the T-CON board... But based on the behavior of the service... -
Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same... -
Hi , I've recently replaced the screen in my Samsung galaxy ao2s, at first it wouldn't even turn on, it had the charging symbol on the screen when plugged in but the green circle wasn't going around to show it charging....
Ive eventually managed to get it on and working but it's very temperamental...
The battery icon always reads as 50% , when the phone goes into lock screen mode i sometimes can't get the screen back on unless I plug the charger in to get it to light up, also it keeps putting the camera app on.. u think it could be something to do with the side buttons. ...05-26-2024, 12:05 AM -

HI guys!
I've got a Samsung LH82QENELGC/EN with a problem and need some advice and I hope this is the forum to use?
I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. 😊
the TV is powering up, working as normally and picture is all good, except a 1.5-inch-wide vertical line of snow/static across the screen.
This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when...
