Re: Sharp LC-70LE650U
That tab driver is burnt up. Only thing you can try is to remove all the tabs on that side. There are plenty of threads here describing how to do it.Comment

Re: Sharp LC-70LE650U
Yes, I agree with you, so the thing left is the other lines on the far right must be a loose connection on the bottom tabComment
-
Re: Sharp LC-70LE650U
the vertical lines could be caused by the side tabs depending on the fault. Before doing any kind of "one way removal", you need to disconnect the small corner cable on the bottom of the set that interconnects the bottom edge boards to the side edge boards. If the vertical lines go away there after, then the problem is with the side tabs / side edge boards BUT if the vertical lines are still there, then the problem is with the bottom tabs / board on that side and is likely not repairable / saveable.Comment

Re: Sharp LC-70LE650U

Hello everyone,
I recently got a model Sharp TV, and I've noticed that the green power LED is flashing without any specific pattern. Additionally, there appears to be no voltage coming from the power board. I haven't observed any leaking or bulging capacitors, although the top of the larger capacitor doesn't seem to be perfectly flush with the jacket—if that makes sense.
Has anyone dealt with this issue before? -
Hello,
I bought Sharp LC-47SB57UT 6 years ago. I had to have a vhf antenna to pick up one local station(koco channel 5 OKC). It has worked great up until a week ago. Sometimes I couldn't get channel 5, now I can't receive it at all. I can hook up a digital convertor box I have from another tv and can receive channel 5.
I think the antenna and cable is ok. I doubt that this would be the tuner board or possibly something else.
Any ideas where I should start?10-24-2024, 03:11 AM -
Hi everyone,
I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.
🛠 Original Issue
The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.
I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.
⚠️ New Problem: One USB-C Port Only Works in One Orientation... -
I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!
We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre... -
I have 2 tp4056 to charge and 2 18650 cell, so i have connected both the charger in parallel with the cell so that it will charge both the cells seperately, i wanna drive an 5v led display with the output from each tp4056 connected in series with a 5v voltage regulator to pull the voltage down. So can i connect the output of both the tp4056 in series.
