Re: LE 42LE5400 - no sound/picture
all radio shacks within 50 miles of me shut down several months ago. I don't know of a repair shop that would sell resistors - but I can ask them if they'd make an exception. Thanks for that suggestion

Re: LE 42LE5400 - no sound/picture
As soon as I plugged the TV in (after making the connections as you described, with the resistor), the backlight came on!
(I then used the remote to turn the TV on - just to see if I'd get the boot up animation or the menu - but nothing else worked - the backlight stayed on).
Does this mean that it is the main board that is faulty, and that replacing it should get the TV to work? (with the backlight on, should the TV have been functional?)
ThanksComment

Re: LE 42LE5400 - no sound/picture
That means beside the failed BL-ON command signal you also have other problems as well, if it is just the failed BL-ON then you would have pictures and sound and all other functions of the TV, so you do need new main board.Never stop learning

Re: LE 42LE5400 - no sound/picture
Thanks. I'll look for the main board replacement. shopjimmy doesn't have the board (with low chances of it being in stock) - will need to look at eBay - will try LG directly as well.
I appreciate your help with this.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... -
So here we go with another screen short TCL. For this exercise left and right will be reference looking at the screen.
The person I got this TV from said the color was bad in a vertical fashion about 1/4 of the way over the left side of the screen. Shortly after the symptoms below started.
Power Supply, main and T-CON board are working.
Symptoms: The TV has backlights but no picture with both FFC's attached to the T-CON and does not respond to the remote or buttons, and the TV appears to continuously re-boot.
Unhook FFC from left side... -
Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
Hello Everyone,
This is my first post so I will try to be as precise as possible without making this post too long winded. Unfortunately I don't have pictures of the original problem but I included images of the TV internals.
I have a Sharp 70LE660U. The problem started a few months ago with the bottom row looking out of sync and was dark on the left side and then fading to transparent on the right side. Shortly after, a dark cloud appeared in the center of the screen. The dark cloud started small and shaded but the image was visible. It also affected the menu area....
