Re: No Picture Samsung LED TV
I would use a slow blow / time delay type - the very fast acting may blow under normal in-rush currents.

Re: No Picture Samsung LED TV

Re: No Picture Samsung LED TV
Yes - you have probably damaged the T-con and you may well have destroyed the panel, and possibly the main board power circuit for the panel/T-con, or LVDS cable if the current was high.
A fuse is there as a protective device, they don't put it on there so you can just jumper it because it'll be fun to see where the smoke comes out, never, ever jumper a fuse unless you really are absolutely certain there is no fault and even then, don't jumper a fuse because nobody is perfect and a fuse is a safety device.
In future, you can use a lower-rated automotive fuse. For example a 1-2A fuse which may be used in a lighting circuit in a car could be used.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: No Picture Samsung LED TV
Should of wired a conventional fuse in using wires, Not just a wire... The magic smoke has been released nowComment

Re: No Picture Samsung LED TV
whats the next move ? possibly binning the tv now ?Comment

Re: No Picture Samsung LED TV
Try and put the smoke back in - if you capture it all in a jar, you might be able to stuff it in the holes it leaked out of (you'll need a smoke injection kit of course; check on eBay), if not, you'll have to buy replacement Samsung smoke, but they only generally sell it to service techs so you'll have difficulty getting it.
more seriously, the lines on the screen point to a panel fault, so I'd probably scrap the set, but it would be good to check a few things first, try and locate what may have burnt or caused damage.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: No Picture Samsung LED TV
is there anything at all i can do to try and fix this ? would it even be worth replacing T-Con ?Comment

Re: No Picture Samsung LED TV
Replacing the T-con could be a waste of money, as you may well have a damaged panel (especially after jumpering the fuse, lots of current may have gone through the wrong paths.) Very hard to to be sure. That IC could be secondary damage or the primary cause of the fault. It's your money. I wouldn't buy one if I were you.Please do not PM me with questions!

Re: No Picture Samsung LED TV
ok i suppose its my fault... should have done what was instructed rather than jumping ahead.. thanks.
to start on another tv now i think, will be paying more attention on this one.Comment

Re: No Picture Samsung LED TV
So i got a hold of another tv but slightly different model that just happened to have the exact same Tcon board.. i tried it in the tv and im getting full picture however i am getting 4x 1 pixel wide lines down the screen at the right hand side. Can this be repaired ?Comment

Re: No Picture Samsung LED TV
Thanks for the explanation, I also have the same problem. I have a samsung models UA40F5000MA, Sound OK, and Backlight OK, but screen black no image. I suspect that there is damage in the T-Con, but I do not understand the "Test Point", I tried to measure the part of the red circle. And get the result Vin 12.85 Volt and in other parts of 6.5 volts. Can you help me. Thank you very much. Sorry but I am not fluent in English, I use google translate

Re: No Picture Samsung LED TV
Use your multimeter set to ohms and measure resistance across the fuse F100 which should measure 0 ohms. Set power off.Willing to help but I'm no expert.Comment

Re: No Picture Samsung LED TV
if the fuse reads short its good re connect the tcon back up in the tv but leave one of the top ribbon cables disconnected turn the tv what do you see on the screen then put the ribbon cable back in and take the otherside out what do you see on the screenComment

It is impossible to have fuse with 0 Ohms reading and have 12.85VDC on one end and 6.5V on the other end of the fuse. So Basically you have 6.35 DCV drops on 0 Ohm! Got to be measurement error.
What scale are you using in Ohm mode?Last edited by budm; 01-19-2017, 11:43 AM.Never stop learning

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... -
This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode... -
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 all,
This is my first post, but long term lurker on the form learning as much as possible about these TV's. I was given this TV as due to a power outage of constant On/off of power to TV. The TV originally would just click on and off (Typical Reboot Cycle). I opened the back of the TV, and troubleshooted by taking the 96 pin LVDS off one at a time to see if I had a picture on either side. I finally fixed the reboot cycle by finding the error on the left side of the screen off connector CN 1301, and the TV would stay on. Further troubleshooting led me to the driver boards where...
