Re: Samsung LNS3241D - No picture, sound and backlight OK
yup, I fixed my LN-S3241D Samsung LCD.....been trying to figure out with lot's of help with the Forums and clue's on youtube, from no picture with sound with vertical lines to the new LCD again I have...answer to mine was the TCON, though I started out with the capacitors which one was slightly buldged...then turned it on and was good for only 10 mins..then went blank with vertical lines again...searched for TCON which was my second obstacle as I learned it from amateur tv techs on youtube..thanks peeps, it was interesting speculating the problem..infact I may make a hobby of it and start fixing other peoples tv problem...thankfully I happened to find/search a former tv repairman whom is retired but still works at home fixing t.v.'s stumbled on him on craigslist here in MN than ordering 75 to 80 dollars on ebay which he sold it to me for 20 bucks...Installed it and was happy to get my LCD back to work infact looked nice! Here's my result within 3 weeks learning from peeps!......Comment

Re: Samsung LNS3241D - No picture, sound and backlight OK
I have a samsung un50h6350af when I turn the tv on the backlight comes on but the screen is black. You can hear the sound. When I took the back off looking at the tcon board if i disconnect the right side ribbon cable going to the led half the screen will work. So I thought it was the tcon board. I went to eBay and bought the same exact one and replaced it. Doing the same thing. Can someone please help me.Comment

by IerwinHello 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... -
by TR103Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds

by MgiffuneI 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... -
by gl4709I 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.

by LaPCon_ITTV has one combo board (VTT55UH160). Symptoms are like this.
When part of the screen is disconnected (white part), it looks like this
