by Jovica123Hello,
i have here Samsung UE55AU8072U no standby light.
Panel model : CY-SA055HGXY1V
Motheboard model : bn41-02844A bn94-16868V
When i press the power button,standby light turn on,after i release it immediately turns off.
Unplugged main board from power supply - BACKLIGHTS COME ON.
I think the motheboard is problem.
I fixed two TV with same mistake,but they were 6000-series,there was a problem with the contents of the w25q40 chip.

by JSin21Hoping 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...4 Photos11-27-2023, 04:54 AM -
by huzoI noticed in manny cases the following : You press the power button and laptop starts turning on and then goes off again, but if you press any key on the keyboard and hold it, the laptop stays on and works fine! The power button works, any other button works , but one button must always be on!
Has anyone else notice that? I was meaning to write about this topic a few times already , but never got to it, and today i got Aspire A315-42 with i5 10th gen. and it has the same issue and i got mad and now i am writing about it!

by Leone22Hello community. I need your help to resolve the problem with my HP envy 15 notebook mod.15-k111nl. The problem is the following: inserting de connector of the notebook, the LED on the connector lights on but if I pressed the power button it doesn't happen Nothing.
I did some tests to verify where the fault could be and I noticed there are 3v but the 5v does not arrive.Furthermore I have a series of mosfets that seem to be in short circuit but desoldering them and testing them on the bench they are good. These are the signals that I found:

Hi Guys,
Got a weird one here. I have a HP OMEN 16-WF0032TX that's in my shop for no power. If I disconnect the battery, and the AC adapter and hold the power-on button on the keyboard, when I connect the adapter the laptop powers on. If I shutdown and close the lid, once I re-open the lid and press the power button, no power. If I shutdown and keep the lid open, when I press the button the laptop powers on.
I have checked around the display connector if I can see anything that doesn't look right, its like an issue with the lid sensor. Has anyone seen this before?...Yesterday, 12:32 PM -
Have a Pioneer VSX-1021 that goes to MCACC flashing as soon as it is plugged in.
If I enter release mode, it powers on, the screen display is correct, but then it shuts down and goes back to MCACC after a few seconds. I can shut it down to standby (w/o flashing MCACC if I hit the power button as soon as release mode finishes the boot sequence).
Entering reset mode and executing a reset doesn't change this.
I am unable to enter service mode to see the error counts - Enter + Power button doesn't do anything, whether from normal standby or from MCACC flashing....-

by MaanuDear Badcaps, i got a HP PRO X2 612 G1 with a BIOS password. Im pretty new to the whole BIOS flashing game but i was able to flash a HP Probook 2 weeks ago with help of this forum.
Now with the HP PRO X2 612 G1 i have the problem that im not 100% sure if i got the right IC and if i am doing everything right in terms of reading it.
I use the CH341A to read the BIOS. The Chip i try to flash got "771AW G GBA 609B" writen on it. I tried with the 25xxx and the 24xxx slot but i dont get a read from AsProgrammer :/
I solderd it out and put it on the 25xxx frame that...2 Photos12-09-2023, 11:14 AM -

by mitsu2kHello folks, this is a last ditch effort. I thought I would seek your expertise before giving up.. I have been working on this thing for over 2 months and have gotten nowhere. Here is the issue:
Inverter powers on and immediately red GFI light comes on and inverter will not complete the initialization process.
There is no error code on the screen. I have removed most of the Y capacitors and tested to no avail.
All relays are good.
I replaced the current transducer- same problem. Checked most of the transistors and diodes and all appear good. I wish I could get my hands...11-13-2023, 07:19 PM

by PontyPCsHi people.
I have been trying to get my head round these issues with the eMMC putting the TV in to a boot loop condition, or completely dead, when a dump of the Boot 1, Boot 2 and USERDATA partitions have been made, the MLC lifetime counter has been reset, using the original eMMC with the RPMB partition intact and the eMMC is flashed with the original dump, Netflix and a few other Apps don't work. i assume all the DHCP keys and factory programmed RPMB access Key will be contained within the original dump, and as we are re-flashing the original eMMC i would expect every thing to work....Yesterday, 10:43 AM -
by Ancient1Hi
Photos tell it all really.
The bulge in the area before the panel Matrix .
To me it looks like a local short that heated inside.
Should I waste my time in flipping the panel , as if this issue can be repaired ?
The distribution board at this end looks ok , though I did not measure anything
What are your thoughts ?
Cheers5 PhotosYesterday, 11:30 AM -
by ozguvenWhen the power is turned on, a snapshot appears on the screen and it turns off. 2 red LEDs are flashing.
I disconnected the power module cable going to the main board. I threw a power on jumper with 3.3 v from outside. The relay is working and there is 12v and other voltages in the power socket.
Where else should I look? All fuses appear to be intact.Yesterday, 02:26 AM -

by x_orange90_xI picked up a 55" TCL 55S451 last week that is not displaying any picture. When it powers on the screen lights up but there is absolutely no picture on it. I can move around the Roku menu with the remote and I can hear it moving around and selecting things. I tried the RESET button on the main board dozens of times as well as the remote bottom combo to reset the tv.
I ordered a replacement main board and power supply from eBay and put them in last night but STILL no picture. I get exactly the same results. The main board in my tv is 30800-000559 40-MR17T4 and the board I received...10-27-2023, 05:28 AM -
