Re: samsung ps42c450b1 no picture but sound
pretty sure that's the model that blows the x-main and there's a firmware update for it.
most opinions are it's best to replace y & x mains together providing the buffer boards are not shorted.
I did all 3 boards on mine because the x-main killed the ymain and I was unsure about the buffers. My buffer was ok, -

Re: samsung ps42c450b1 no picture but sound
yes but the tv powers on because you can here the melody sound as the tv powers up.I do not think you would get the melody with the y and z sus boards connect if their was a short on the y or z boards its like the tv on but no picture and it stays onComment

Re: samsung ps42c450b1 no picture but sound
A short on Vs on these will not cause sound to stop working. AFAIK there is no repair kit yet so you must replace the Y- and X-main.
Can't remember if it applies to these models but the control board LED might blink a 5 sec 2 sec code (5 on 2 off) indicating a DRV RESET fault.Last edited by tom66; 11-14-2013, 08:16 AM.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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 βfading' 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 βnew' 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... -
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...
