They are pretty close, so I am not sure why you are getting different DC voltage measurements.

Re: Samsung PN50B430P2DXZA
What about LED-s on control board. It appears to have 2 of them and one is constantly blinking while TV is on. Is this correct for LED-s?Comment

Re: Samsung PN50B430P2DXZA
The guy who sold me x-main from eBay will ship another one. I will try that first and if 3rd one looks same then will move to something else. This tv has same picture with or without Panel orange cables disconnected from x-buffer. If still problem I will ship to you.Comment

Re: Samsung PN50B430P2DXZA
I'm actually interested in what might be causing this problem because it sure is bizarre. Your X-main appears to be working, your control board appears to be working and the X-buffer is OK. Only missing link is a problem with the panel but what exactly?
That doesn't mean I expect a half-broken 50" Samsung to end up on my doorstep. I've enough projects as it is...Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Please see attached picture of y-main connectors. Y main VSC reads -192 but when I check any pin of orange cable from picture I am getting -12 V. Can anyone check on any plasma what voltage is there supposed to be.Attached FilesComment

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...
