47lv5500 No sound No picture
Okay so I have a 47lv5500 TV and it doesn't have any picture it's just a blank screen, I tried the flashlight thing and there is nothing. also there is no sound. the only thing that seems to be working is the on/off button. I've replaced the T-com bored but it did nothing other then get rid of the lines when on the screen.

Re: 47lv5500 No sound No picture
I fixed a few of the LW and LV series. It is either a faulty PSU, faulty mainboard or worst case faulty panel. Any of these can have the same fault symptoms.
Check the fuses, transistors and voltages of PSU. If you find anything abnormal, replace the power supply or buy a repair kit from ebay.
If the PSU is good, then it is most likely the mainboard at fault. Buying a replacement mainboard can be expensive. Fortunately there is an easy way to save your old board. Some people say to use the oven method and bake it. What I did was invested in a hot air gun and blasted hot air at the heatsinks at 250C for about 2-3 minutes. The hot air gun I used was the BOSCH PHG 630 DCE. Works a treat everytime.
There is one last possibility and that is the panel. All you can do is pray its not the panel.
I have never come across faulty T-con before.
Hope this helpsComment

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... -
so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...
