Take good photos of this non-working plank so you can see what's on it.

Try to isolate these pins (CKV...) on the cable with tape.Attached FilesComment

Re: Hitachi 58HK6100U LED TV - Sound but No Picture
Here it is necessary to experiment with these contacts, try both 14 and 15, 16, also try to isolate them in turn ...
This microcircuit is responsible for these signals, and you have damaged drivers on the one hand, which must be isolated.Attached FilesLast edited by lotas; 09-03-2022, 03:26 AM.Comment

Take a good quality photo of this chip so that you can read the control points near it.Attached FilesLast edited by lotas; 09-03-2022, 03:27 AM.Comment

First you need to isolate these 9 contacts, these contacts go to the bar, you can check with a multimeter where they go (which pins of the connector.Attached FilesComment

Re: Hitachi 58HK6100U LED TV - Sound but No Picture
Yes, try.
And what contacts do these points go to.Attached FilesComment

Re: Hitachi 58HK6100U LED TV - Sound but No Picture
Until 19, this is a lot you have glued, from 2 to 9 (inclusive) and up to 14 (inclusive) try
1 does not need to be isolated, this is VGH, you need it.
In general, you need to experiment with these contacts, you can achieve a normal picture if you're lucky.Last edited by lotas; 09-03-2022, 07:52 AM.Comment

Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
No picture but you hear the TV static (white noise) playing loud and clear.
The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
But it seems they didn't get too far and just left it.
When I first took a look I was amazed at how pristine the inside looked.
Its as if the TV had been in a time capsule.
Caps looked like they were just pulled off the self.
Copper coils had no sign of corrosion on... -
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... -
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 have a VIZIO E70-E3.
Symptoms: Black screen, no picture, but LED backlights are working.
I probed the power board and voltages are as listed on the board.
Main board appears fine, too.
I believe the problem is either a bad T-CON board, or connection to LCD, or bad LCD.
There are two separate ribbon cables feeding the LCD.
If both are connected, the screen is black.
If only the ribbon cable that feeds the right side of the screen (when viewed from the front) is disconnected, the left side of the screen shows picture and...
