Re: Another Samsung HP-T5064, Good Sound, No Picture
Well Vscan (Vsc) is measured across this blue capacitor.

Re: Another Samsung HP-T5064, Good Sound, No Picture
Measuring across that cap overloads my meter.

Re: Another Samsung HP-T5064, Good Sound, No Picture
Set your multimeter to manual range (400V) and see if it can read the voltage. If not, time to get a new multimeter.

Re: Another Samsung HP-T5064, Good Sound, No Picture
If the output is pulsing that will happen, the autoranger on the meter is too sensitive.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Another Samsung HP-T5064, Good Sound, No Picture
Set your meter to a high DC range (400V/600V/1000V) using the range button. It'll stay locked in that range. Right now it is struggling to autorange as it receives the pulses from the power supply.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Another Samsung HP-T5064, Good Sound, No Picture
Looks like I need to return this meter. I can turn off auto-range and set the meter to 000.0V and as soon as I touch the probes to the blue cap, "AUTO" pops back on and the meter goes crazy again. If I probe Vs at the connector, it stays locked.Comment

Sounds like a bad design to me. While it might not be faulty, it's probably a bug in the controller, and it's not your problem to get fixed.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Got the Y-Main repaired and the set works. Now to try to find a base for this thing that doesn't cost more than the repair to the board.Comment

I bought a refurbished one via eBay. I'll get $50 when I send my old one in. Without being able to really identify the problem, I figured this was my best bet.Comment

Yes, a few of the MOSFET's were replaced. Looks like a very good job.Comment

Re: Another Samsung HP-T5064, Good Sound, No Picture
shorted mosfets will be the common issue with these.
A stand has been hard to find for these. I don`t know why.
I normally just weld up two legs that bolt to the back of the tv and paint it black.
I leave room under the tv for a cable box and / or dvd player.Comment

Re: Another Samsung HP-T5064, Good Sound, No Picture
It's like you're in my head. I've been looking ALL DAY for a stand. I've discovered that the stand from about 10 different models will work. I'm hoping to find one nearby with a broken screen for cheap. Maybe I can get the base and remote that I need and sell off the parts to get my $$$ back.Comment

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... -
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... -
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... -
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...
