Can I turn on the TV with the Ribbon cables disconnected from the display panel. Just the Y Buffer connected to Y Main and the rest of the Circuit. This is on a Samsung.

Re: Y Buffer Question
Usually Yes you can, unless it's a newer model.
I have a Samsung pn60e550 that has a fault detection on Y main.
If everything is not hooked up and working it will shut down and not make VA volts. -
Re: Y Buffer Question
I see, now that I think about it, it does shut down. Thanks for the info.Comment

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
Hi everyone,
Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.
Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.
I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue.... -
Hoping someone here could possibly help. I have a few questions in regards to compatibility with main boards. But I'll give a quick short run down on what's going on first;
I have Samsung Smart TV UA65MU6100WXXY version DA01
Now years ago it started intermittently playing up after a lighting strike. Lighting hit the block of units i was living in at the time. Ever since that night the TV started having a mind of its own, It would randomly turn itself off or on, and all inputs stopped responding like HDMI, aerial, but USB still worked. Anyway, over the next few months... -
Hello!
I just got a Samsung TV model HG75EJ690UB 75" and 4K
. It is a hotel TV, with a slightly different version of the Tizen operating system than the TVs at home.
Being a hotel, it is covered in many functions. With the service menu I can unlock some, but not others. For example, I can't install apps like Netflix etc...
The fact is that it seems that I can replace the main by a, say, "normal". I think the one that corresponds is NU7105, ref BN94-02635. At work, which is a convention center and a hotel, I have many TVs from 55" to 85" that...
