I have a TC-P42X5 when I connect power and press the power button the red led on the front comes on but no blinking no relay clicking no picture and no sound. I have tried powering it on with everything unplugged from the board and no change. I do have steady standby power. Any suggestions where to go next?

Re: panasonic TC-P42X5 red led no picture no sound
Does the light on set blink when you're using the remote...?
If not, check remote and check wiring etc of the remote sensor on the set.TELEFIX

Re: panasonic TC-P42X5 red led no picture no sound
It will turn on with the remote or rather the red light will turn on when I turn the set on with the remote but no blinks after thatComment

No relay. I'd suspect A board, maybe wait for tw2005 to chime in as he's got some experience with this model I think?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: panasonic TC-P42X5 red led no picture no sound
Except for some possibly very early Panasonic models, on the US versions they don't go green ever. they don't even have a green LED. Not sure why! Red light is lit in standby AND when running.. with no clear distinction between states...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 ‘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... -
Hi, I'm new here and looking for some advice on how to diagnose an issue i have with 2 samsung TVs.
I have a UE32J5500AK and a UE48H6400AK both with the same issue of red light but nothing happening on the screen, the red light responds to remote or button press by flashing once but stays red. I have searched forums but most turn up a blinking red light.
I have tried replaceing the power board on the UE32J5500AK last year but this resulted in the same outcome.
The UE48H6400AK recently developed some small bright areas on the screen, then last week would not power...
