hey all, i have a sharp LC32D44U that will not stay on, sometimes it will come back on by itself then turn back on. I can hear the relay clicking when it does this, and it's flashing a error code 2x power flash and 7x OPC. I found a service manual for the tv at https://www.scribd.com/doc/142227777/Sharp-Lc-32d44u and it says the reason for this flashing is a main failure, and describes Main microprocessor detection error (FAN error, 1bitAMPerror, etc.)The details are displayed in “ERROR STANDBY CAUSE” onpage 1 of process A mode for the main microprocessor. I cant seem to find where in the service manual it goes in depth on that error code issue or what to test. i will post pictures tomorrow since it's dark here right now and pictures are blurry, was hoping someone was familiar with this issue. thanks everyone

Re: Sharp LC32D44U
Just wanted to post back on this tv, I didn't get around to posting pictures of the boards due to vehicle issues that required immediate attention.
The issue with this tv was a bad bulb. I realize there were threads started on this model that the flashes indeed indicated the bulb was an issue, however the service manual didn't pinpoint this being the issue for me given the amount of blinks I had. From further investigation, this particular TV seems to be notorious for blown bulbs, and I fear only replacing one means the other may soon follow behind and go out too, but with limited money I will be replacing the one that is blown, and moving the new one to the top or bottom since the blown one is in the middle. I assume the new bulb may or may not be brighter than the others which is my reasoning for moving an old one to the middle and placing the new one elsewhere. Thank you everyone for all the help you provide others. -

Hi Folks
I am searching for a Sharp 32BC2K0 Service Manual
Sharp 32BC2K0 << Could be an "O" as in Orange or a Zero
Fault - Coloured "Bars" very thin all across the screen.
I would like tho get the values for the 2 Resistors and I believe a Missing Capacitor.
I would Like a Service Manual, that has the component values, and locations, as the PCB isnt that clear as for designations
Is there such thing as a Boardview for this TV?
I will Post the Photos in a second
Thanks
Stay Safe !... -
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...
