Re: Toshiba LcD TV 40L1333b sound no picture
registered to say thanks for the info, my toshiba backlight died and it was the connector between the 2 bottom led strips! Weird thing though - when i reassembled it, the backlight came on but no image, nothing. Left it overnight as I couldnt be arsed to open it up again, and next day its fine! whats that all about? Some error state that the logic board went into when the led power failed, didnt clear, but did after a certain time??Comment

Re: Toshiba LcD TV 40L1333b sound no picture
yeah loose cable is what i was expecting to have to look for today. This is the first tv ive tried to fix but ive dealt with quite a few laptop screens and its not much different. can the connector seat itself somehow? i noticed the connectors had no tape holding them in, which laptop connectors always do.Comment

Re: Toshiba LcD TV 40L1333b sound no picture
Not normally no they have little secure snaps to hold em down. I have never seen any fail with that type of connector and repairs over 200 vestels. You might just not have seated it properly.Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only. Anyone Doing So Will Be Banned Instantly !

Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds

- 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... -
Hi Everyone,
I'm working on a Toshiba 37AV500A Regza TV.
The issue:
TV was working picture and sound went out. Green stand by light stayed on, It will respond to the power button being pressed (goes in and out of standby)
The TV will very intermittently work for around 40 mins then stop. This doesn't seem to matter if its hot/cold unplugged for a while etc.
I checked the PSU voltages and everything looked good.
No bulging caps or signs of heat.
24v aud = 24.41v
12v = 11.98v
5v = 5.062

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...
