This tv has a good backlight and sound. Has stand by light and will power on and off. My first thouhgt was a bad T-Con, but for the price of the t-con i could pay 30.00 and get all 3 boards. So i replaced all 3 boards new from shop jimmys. Still have the same problem. Is there anyone that can shine some light on how to fix it??

Re: Samsung Un50h5203f Backlight and sound no Picture
Both sides?Comment

Re: Samsung Un50h5203f Backlight and sound no Picture
Check BOTH sides of that fuse to see if you have 12 volt like Hamie and Budm asked.
If you do,disconnect one ribbon from the t-con and try,then reconnect and disconnect the other one,see if you get halve a pic.Proud owner of dozens of broken TV's and many,many,many boards.

Re: Samsung Un50h5203f Backlight and sound no Picture
Good catch. You might want to put alot more tape over it before you screw it all back together, just to be safe.Comment

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, 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... -
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. -
TV has one combo board (VTT55UH160). Symptoms are like this.
When part of the screen is disconnected (white part), it looks like this
Resistance and voltages (I don't know if they are good or not). The inductor with 0ohm/0V seems to be connected to GND.
I haven't noticed any shorts on rails listed below:
VGH - 30V
VGL- -9V
VAA - 14V
VCOM - 5.6V
STV - 11.95V
LC1, LC2 - +30/-12V
All CKV lines (no shorts between them) looks the same:
