Re: LN52C530 sound, picture, no backlights/volts from power supply
UPDATE:
Today I received the capacitor and some fuses and installed them in to the TV. Here's some pictures of the solder job and the tv WORKING!
I know it's been a while since I posted this but as I fix the TV's I've been asking about I will post the results for each one as I get them fixed.
Here's a big THANK YOU to EVERYONE who helped with troubleshooting on this one. I appreciate it!Attached FilesThey call me......."threadkiller"

Well, I just subbed to this website. A friend was getting rid of his Samsung LN52C530 TV because it was exhibiting exactly what's described here: sound but no image. Even if I'm no TV repairman, I decided to attempt fixing it. Started surfing the web for leads. Yesterday while watching Trump win the presidency (poor MSM still won't proclaim his victory!), I red this thread and found that failed polypropylene cap in the power board. Ordered the replacement cap from Amazon because I wanted it FAST. I will receive it today and will post back very soon.Comment

Well so much for Amazon's "so called Prime" membership. It was said that I would receive the cap the next day. That was yesterday. The cap came in this evening around 6:30 P.M. 🙄
It's now 9 P.M. and I've been watching the TV for at least 1 hour now. laughing my a** on a Jeff Dunham's Controlled Chaos monologue of 2011.. That bad cap was it. Unbelievable! budm, thanks for the fix man. May you be someway rewarded for your competence! And of course, thanks DXseekerMO for starting this thread.​Comment

When I turn tv on, the backlights come on but there is no sound or picture. I have read that these tv's have problems with the panels going bad but the "no sound" has me questioning if the main board is bad. Is there a way to troubleshoot the main board to determine if that is the problem? -
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... -
Hi all
I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.
Symptom:
No picture no sound.
When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
No sound at all.
What I tried:
1. I tried unplugging the left or right ribbon...
